A year of blogging – a look at some favourites!

While looking to the future of my blog I thought it would be good to take a quick look back at my favourite posts over my first blogging year so here they are…

My most poplar blog of the year was also one of my personal favourites, I took a quick look at What’s in a hug and ended up having the whole family counting to 20 ever hug we gave ;0)
Counting to 20 and sharing the love!
I got to ramble on about one of my favourite plants… Lavender … what is not to love about this wonder plant? I shared some things I like to make with it and even got to try out a delicious cocktail…. the things I do for blogging! We have since tried out a few more recipes and ideas so there will be a Part 2 coming up shortly.
Looking back I notice that wild plants and hedgerow herbs featured a good bit in these posts, my two favourites being The passing of time and A fistful of Love;
A fistful of love
I did a guest post earlier in the year on the wonderful Science Calling blog where I got to to talk about Science through the eyes of a child!
Myself and my Junior Science team had great fun each weeking preparing experiments to share on the Fun Friday posts, our three favourites would be Making Butter, Anything that glows and Exploring Density.
My wonderful Junior Science Team
I really enjoyed running an interview series on my blog and getting to find out more about four people who have really inspired me in their various fields of Science and/or Nature and how they share and communicate their areas of expertise with such diversity and passion: 
I spoke with….  

                     Jason Tammemagi about how he creates and produces children’s animation
                            Michael Bell of Nature Learn on Wildlife education in Ireland
                   Dee Sewell of Greenside Up on Community Gardens and Growing your own
                 Una Halpin of Wildways Adventure Centre on getting families back into Nature

I got to chat about my wonderful Dad on Father’s Day and explore the science behind the bond that is often overlooked.
These blogs are often inspired by questions asked by my children so I thought this round up should include one of these posts; Hard to choose a favourite but this one has particular sentiment for me as it reminds me of a lovely family holiday and it was one of my first blogs of the year.
A great boost for me on a personal and blogging level came in September when I joined the Irish Parenting Blogger Group*… the support, advice and encouragement from these wonderful bloggers has been invaluable to me ever since.  I was delighted to be part of an IBPG blog march during National Breast Feeding Week in October, when I got to share some of my own experiences.

So that is my round up for the year of 2013, thank you all for reading and I hope you stick around to read more in 2014

*Many of my fellow IPBers are doing their own blog round up, check out the IBP Facebook page for links to their blogs.

A glance back and a look forward!

I have been reading lots of “end of year” reflective blogs and I am loving them, but feeling reluctant to write my own. I set myself the challenge at the start of 2013 to write a blog for the year. I had given up making the typical New Years Resolutions a long time ago as they had always fizzled out before January was over. However, when I really set my mind to something I am a bit like a terrier, I just don’t let go. So my resolution at the start of 2013 was a little different… I set myself a year of blogging… a start and a potential end point if I chose it at the end of the year. I also decided to start in the middle of January, not the very first day as I knew that to be the first stumbling block for success for many.

One year on and I have done it. I have toyed with different writing styles (did you notice??), I have changed design a few times (once completely by accident when I deleted my entire layout!!… I learned how to back up after that one!). I started with the very long, more scientific posts (which I do still love to do from time to time) and moved on to some shorter, more general ones. I started blogging once a week and then increased that. I introduced things like the Mystery Creature spot at the start of the week and the Just a thought posts which have become some of my favourites!

I started in that pig headed and totally naive manner that seems to be burnt into the core of my character (just ask my hubby… I think he finds this trait both totally frustrating and admirable all at the same time!). I wrote, I clicked “publish” and then I sat back and waited. Maybe I just expected an automatic audience to come flooding to my words in an “if you build it they will come” kind of way – as I said Naive with a capital N! Turns out it doesn’t work like that… who knew? I have learned a lot about social media through this blogging adventure and in so doing I have met some wonderful people and have been helped, supported and inspired by many. This in itself has made the years adventure so worthwhile.

The only disadvantage to my resolute and finite plan to blog for the year is what do I do when the year is up? Now I understand my own reluctance to write this post. I have come to the end and I need to decide the next step.

So what to do next?… well I have really enjoyed the writing and have found that I have learned so much on so many different levels. In fact I have enjoyed it so much I am not ready to stop. I feel this blog is still an infant and has a lot of growing to do. It is time to make some changes though… firstly, structural ones… so watch this space as things will get shaken up a little and we will see what the blog looks like when the dust settles. In the mean time if you have any suggestions as to what you might like to see more of on this blog, or less of, just let me know in the comments below. Your feedback would really make a great end to my blogging year and a helpful start to my next blogging phase… so go on… don’t be shy!

All that remains now as the year closes in is to say a BIG thank you to all who supported me in my blogging adventure so far. A special thanks to my hubby who has patiently supported me while the dinner got delayed, the laundry (and kids) stayed unwashed and the conversation paused, all until a post was finished. To family and friends who edited, proofed, suggested and cajoled the blog along with me, especially in the early days – my heartfelt gratitude; and to all those who I have met along the way and have offered me such invaluable help, support and advice, thank you all, it is very much appreciated and has not gone unnoticed!

So my last words of the year are to wish you all a wonderful New Year, may your 2014 be full of health, fun, laughter and happiness…. and keep watching this space because it seems I still have lots more writing in me xxx

An unexpected Christmas guest

We like to get a real tree for Christmas every year, the lovely smell of the pine really adds to the festive feeling! Sometimes we get more than we expected… a few years ago we found a beautiful nest in the tree; this year we found an unexpected visitor… a cute little ladybird.

It is likely that most of our Christmas trees are hiding a multitude of insects in various stages of life cycle and hibernation. In fact a recent article suggests up to 25,000 creatures may be found on one tree alone. These can include mites, aphids, beetles and spiders.  Many, like our little ladybird, may awaken from their hibernation once they are brought into the warmth of the house.  Some in the egg stage of development may hatch but most will just stay resting on the tree and will be none the wiser of their new surroundings, being removed from the house when the tree goes out after Christmas. Even if they do wander from the tree most of these insects pose very little threat to the house or its inhabitants and will often die due to heat and lack of food.
This little guy obviously did waken and decided to take a little walk around his new surroundings. We were glad to see him as we had noticed a real reduction in our sighting of ladybirds this Summer, a casualty of our late and hot weather meant a reduction in aphids and therefore a drop in their food supply. 
Who doesn’t like the ladybirds? Let’s hope the weather is more favourable for these little gardeners friends in 2014.

Here are ten facts about the ladybird that you may not have known…

  • There are about 5000 different species of ladybird in the world
  • Considered a great friend to the farmer and gardener because it eats crop harming aphids, a ladybird can eat up to 5000 insects in its lifetime (an adult may consume 50 aphids a day)
  • The name ladybird makes reference to “Our Lady” as European farmers in the Middle Ages thought they were sent by The Virgin Mary in response to their prayers to eradicate an infestation of aphids that were consuming their crops
  • Ladybirds can be found in many colours, not just red and orange and they can have stripes or other patterns rather than just spots
  • A ladybird’s bright colouring warns potential predators that it may be toxic; as a defense tactic they can secrete a foul tasting yellow oil from joints in their legs
  • A ladybird stays in flight by beating its wings 80 to 90 times a second
  • A female will lay at least 2000 eggs in their lifetime – the larvae hatch within days and start eating immediately
  • Females lay unfertilised eggs as well, these are thought to act as a back up food source for the larvae if normal food supplies are unavailable 
  • Geckos are not the only ones with super hairs on their bodies that allow their gravity defying feats, scientists have recently investigated the molecular structure of ladybird hairs in the hope of one day reproducing their amazing abilities for human purpose 
  • The Harlequin ladybird has invaded Ireland and is a big threat to our 15 native species. Bigger, hungrier and a potential predator this species could really impact the number of ladybirds in this Country. 

Fun Friday – How to make crystal decorations for Christmas

This is definitely one of my favourite experiments…. a little bit of science and a little bit of craft… resulting in some beautiful crystal decorations.

It has become a bit of a Christmas tradition in our house at this stage. Each year we make a new set of decorations to add to last years set, plus they make a lovely homemade gift for family and friends.

Adults and children alike… I highly recommend you try this one! 

So here is what you will need:

Gather all your ingredients

  • Borax powder*
  • Hot water
  • A jug
  • A stirrer
  • A plastic cup or glass
  • Some pipe cleaners
  • Scissors
  • Thread or string
  • A pencil or lollipop stick
  • food colouring (optional)
  • Glitter (optional)

*A little note on Borax powder; you should be able to get this powder in any chemist in Ireland. It will cost anywhere between €2 and €3.50 for this 100 g quantity (which is unfortunately the only size available these days).

Borax is classified as non-toxic by the FDA and is a common ingredient in some washing powder and many skin creams.

It is therefore considered safe to use with children, if the solution splashes on their skin it will do no harm; although it is classified as non-toxic, I would obviously not suggest that anyone actually eat it!

What to do:

Firstly boil the kettle and pour the boiled water into your jug to cool a little (about 10 minutes is good); this bit is definitely for an adult to do!

While you are waiting for the water to cool make your decoration out of the pipe cleaners, it needs to be small enough to fit into your plastic cup without touching off the sides. We are going through a phase of making star shapes at the moment, quite appropriate to the season I think , but feel free to be a little more creative!

Shape your decoration from pipe cleaners… we love star shapes at the moment!

Tie some thread to your shape and tie the other end to the lollipop stick, place the stick across the top of the cup so the pipe cleaner shape dangles in the cup. You may need to adjust the length of the thread until you get it just right. You want to be sure that the shape dangles in mid air and does not touch off the sides or bottom of the cup.

All ready for the Borax solution

Now it is time to prepare the borax solution… you need to add the borax powder to the hot water and stir it in until no more will dissolve in the water. You will know that you have added enough when some of the powder stays at the bottom of the jug, no matter how much you mix. You will need at least two tablespoons of borax powder in 250 ml of hot water, but I would advise adding more if the powder is still dissolving.

When you are happy that no more powder will dissolve in the hot water then pour this borax solution into the cup making sure you cover the pipe cleaner shape completely. If you wish you can add a few drops of food colouring at this point and mix it into the borax solution. You may also want to add some glitter, just sprinkle a little into the cup. I like to use a fine glitter if doing this step as you don’t want bit pieces of glitter dropping to the bottom of the cup in case the crystals form on them instead of the decoration. If I am adding glitter I sprinkle a small amount onto the surface of the solution in the cup them I lift the stick up and down so the glitter sticks to the decoration. I repeat this step a few times until I am happy that the decoration is covered in enough glitter!

And that’s it… all you need now is to leave your cup somewhere safe overnight and wait with patience!

Check it the next day and you will see your decoration is covered in lots of lovely crystals! Remove the decoration from the cup and place on a piece of kitchen paper to dry.

Enjoy!!

The science bit:

This experiment teaches us about making saturated and super saturated solutions and about how certain minerals will form crystals.

If we dissolve the Borax powder in water until no more will dissolve we have created a saturated solution. The water cannot hold any more of the powder. However if we heat the water it will be able to dissolve a little more powder and this is what we do when we add the Borax to the heated water. When we heat a solution to be able to dissolve more material it is called a super saturated solution! However as the water cools it cannot hold all that extra powder any more and the Borax comes out of solution. This time it comes out as a crystal and not a powder and these crystals will form if they have a structure to form on, in this case the pipe cleaner structure.

A crystal is a solid structure made of an ordered 3-D pattern of atoms and molecules. Once they are given enough time and space to grow most minerals dissolved in water will form crystals.

Here is our little Christmas Decoration Making 2013 Album, hope you have as much fun!

We hope you enjoy this experiment and if you do get to try it out let us know how it goes for you, or even better… share photos of your own decorations with us!

Why is snot green?

We have had a recent bout of coughs and colds in this house. You know how it is once you become parents… there is suddenly no subject too gory or vile for conversation. Serious discussions about nappy content, vomit content and the like are par for the course in rearing these little organic beings. Hubby and I had one of these conversation in bed the other night…. yes, 13 years together and romance is obviously still very strong between us!

The chat started out about what level of a cold each child had and ended with himself asking…

“So, why is snot green then!”

Under normal, healthy circumstances we produce mucus in the lining of our nose, sinuses, mouth, airways, lungs and digestive tract.  This mucus is deliberately made by the body and acts to lubricate the airways and also to trap any invading viruses or bacteria, or any dust or other particles. Mucus is made by the cells lining the airways. Our bodies typically make about one to one and a half litres of mucus a day.

Most of the time the mucus in our airways is fairly clear and stringy. However, when the airways come under attack by infection the body sends in its army which includes cells called nutrophils. These nutrophils attack the infecting bacteria or viruses, killing them with their chemical warfare.  They secrete an enzyme that contains iron and it is the iron that gives the mucus its wonderful array of colours from yellow, orange brown and the most common… green!

Here is a hint… they are appropriately named for the season that is in it ;0)

Interview Series – Science Wows talks to Una Halpin of Wildways Adventure Centre

This post is the fourth in a the interview series looking at Science and Nature communication through different media in Ireland

This week I talk with Una Halpin, of Wildways Adventures, to find all about her business and her passion to get families outdoors!

Una Halpin is the owner of Wildways Adventures, a company that introduces children and families to nature, heritage and the outdoors in a fun and relaxed way.  Una has a BSc in Geology from Univesity College Cork and an MSc in Environmental Engineering from Queens University Belfast and has worked in the Environmental Education Field since 2004 including three years as a field instructor in the Killarney National Park Education Centre and five years as Education Officer in Castlecomer Discovery Park.  Una has developed and delivered science education programmes to primary, and secondary school students as well as adult groups but her greatest passion is in getting families outdoors exploring nature and the outdoors together.

Hi Una and thank you so much for agreeing to take part in this interview series.
Firstly I would like to find out a little about yourself and how you got into a career in Environmental Education:

 

Is this something you always wanted to do?


When I was younger, I never had any clear idea of what career path I wanted to follow.  I was interested in wildlife and the outdoors from a young age and I suppose I had a vague idea that I’d like to do something in that line but that was about it.
What path did you take to this career? What training was required?


I suppose I took a long route to the career I’m in now but each of the steps taught me something new and I like to think I’m combining all of my previous experience in my current role.
When it came to decision time in school and I had to start looking at possible study options and the CAO, I chose Earth Science in UCC.   I had decided I wanted to do something in the environmental field, but in the end I chose Earth Science because I loved physical Geography and I was fascinated by rocks and the formation of the landscape.  I loved my college course, and graduated in 1997 with a BSc in Geology.  I then spent a year working in the Groundwater section of the Geological Survey of Ireland before completing an MSc in Environmental Engineering in Queens University Belfast.
After my masters, I worked for two and a half years in an environmental consultancy in Dublin working mainly in the area of soil and groundwater pollution before leaving to spend 6 months travelling in India and Sri Lanka.


It was after my return that I became interested in the whole area of Environmental Education.  Shortly after my return home, I did my first work camp with Groundwork conservation volunteers, clearing Rhododendron from the oak woods of Killarney National Park and was determined to return.  I’m still involved with Groundwork and even met my husband through the work camps.  The following spring I got the chance to return to Killarney National Park to work in the Education Centre.  For the first year, I worked on a casual basis, whenever an extra instructor was needed and volunteered with the park rangers on the other days.  I lived in Killarney for 3 years overall.  I spent the summer of 2005 co-ordinating the Groundwork work camps and then took part time work in the cinema while continuing to work in the Education Centre until I eventually got taken on as a full time member of staff.
In early 2007, I took on some contract work for Castlecomer Discovery Park who were about to open a new visitor centre and coal mining exhibition and wanted to register as a Discover Centre with the Discover Primary Science and Maths Programme.  I put together their education programme, workbooks and teacher notes and started writing content for the website and was then taken on as Education Officer in March 2007.


I spent five years in Castlecomer.  I started with the Primary school workshops and school tours and over the next few years went on to develop a number of secondary schools programmes and also family events and activities.
If you look back to your childhood, is it obvious to you now that this career was a likely path for you?


Yes I suppose it was.  We were always an outdoor family.  Sunday afternoons were quite often spent walking in the woods or climbing mountains.  I was carried up my first mountain in a sling at six months old.  At the age of 7, I joined the Brownies and went on to Guides and remained involved with the Irish Girl Guides for over 24 years.  Even though I’m no longer actively involved I still consider it a huge part of my life and I believe that many of important life skills I’ve acquired come from my time with the guides. 


For me, the connection with the outdoor world and nature defines who I am and always has.  All of my happiest childhood memories involve being outdoors: walking in the mountains; at the beach; swimming in the river; picnicking in the woods or just playing in the back garden.   I remember one family holiday in Connemara when I was about 12 or so.  We rented a house in the middle of a stretch of bog with the mountains behind us and a stream running past the front gate.  I spent most evenings very happily sitting alone beside the stream watching the water flow by.  I feel at home when I walk through the woods, I love watching bats swoop around me at dusk or learning the name of a new wildflower or bumble bee and nothing compares to the feeling of stepping out of a tent in the early morning when the dew is fresh on the grass, the sun is just coming up, the birds are singing and everyone else is still asleep.
You now run your own business Wildways Adventures…..
Can you tell us a little about it?

I set up Wildways Adventures in July 2012.  My tagline is “Come Explore the Real World” and my mission is to get children and families to engage more with the world around them and explore nature and heritage in a fun and relaxed way.  There is so much emphasis on the virtual world and digital technology today that people can often lose sight of what’s around them.  Many children will be able to tell you all about endangered polar bears from watching wildlife documentaries but very few will be able to identify native Irish animals.

I do this through running schools workshops, family nature trails, bug hunts and outdoor treasure hunts and through working with other tourism businesses, youth and community groups and local tourism bodies.

At present, it’s just me but I can call on family and friends, especially my husband, to help out when needed and I eventually hope to employ a small number of like-minded people to assist with planning and running events and activities.
Why did you decide to set up this business and when? What inspired you?

I had been considering it for about a year before finally taking the plunge.  I was inspired by my own connection with the outdoor world and my desire to introduce others to the outdoors.  Having my own child also had a lot to do with it.  I wanted to have more flexibility in my working life to be able to spend more time with him and also to build something that he can be involved with.

 

I do a lot of work with schools and I love introducing children to nature and seeing how much enjoyment they get from it.  Even in my indoor classroom visits, talking about rocks and fossils I love seeing how much they enjoy touching the rock samples and asking questions about them.  I like to think that I inspire some of them to look more closely at the world around them when they go outside and understand a bit more about the landscape and the forces that shaped it.

Working with children is very rewarding but I think there’s a niche for more family activities.  There is no end of choice when it comes to children’s activities but not so many things that the whole family can get involved in.  Also if you want to get children interested in nature and the outdoors, you need to get their parents involved too.

So much emphasis nowadays is placed on keeping our children safe, that we are unintentionally placing huge restrictions on their freedom.  There’s also a trend towards more high-tech toys and more new and exciting forms of entertainment but in most cases, the activities children will enjoy most and remember for longest are the simpler ones.  Taking them outdoors and letting them explore opens up new possibilities for them.  By its unpredictability, nature encourages observation, imagination and problem solving skills.  I believe that any child who is encouraged to love nature and spend time outdoors will sleep better, be healthier in mind and body and will rarely be bored.  By getting outdoors with your kids, you can let them have the freedom to explore while at the same time keeping an eye on them.
Your work has you working with children, families and the local community in a number of different ways;
Can you tell us a little about each aspect of your business?

I’m involved with a number of schools programmes.  I run energy workshops for primary and secondary schools on behalf of the Sustainable Energy Authority of Ireland (SEAI), I train primary teachers in science activities as part of the Discover Primary Science and Maths programme and I go around to schools with my own workshops on Rocks, Minerals and Fossils or various nature and biodiversity topics as part of the Heritage in Schools scheme.

I run family activities such as nature trails, bug hunts and themed treasure hunt style trails in County Carlow.  My most recent event was an afternoon of Halloween themed family fun and was run in conjunction with The Tea Rooms at Duckett’s Grove in Carlow.

I also work with other businesses and community groups to organise and run family activities or to put together education packages or family activity programmes.  I have run activities and led walks for Carlow Tourism and organised activities for local summer camps in Carlow and for community Gathering events.  Last year, I put together the new Discover Primary Science and Maths programme for Birr Castle and have done some work with Huntington Castle.
What are your favourite aspects of each side of your business?

With the schools I love it when the children ask questions that really show that they’re taking an interest in what I’m saying.  I’ve been asked some great questions by children that have made me think and that have encouraged me to learn more myself.

With families, I love it when the parents get interested and tell me that they’ve learned something new and have enjoyed it.

With other businesses and community groups, I love being presented with a new challenge and working on new projects.  I love being able to help showcase nature and heritage and design activities that will make them more accessible to families.
Do you see an increase in awareness and interest in Nature and the environment in Ireland?

I think there is more of an interest lately in nature and the environment but it’s a slow process.  Some families are starting to get out more and go for walks and are beginning to realise the benefits but there is also a huge rise in amount of time children spend indoors watching TV and playing computer games.  During the boom years, families were more likely to spend their Sunday afternoons in a shopping centre than out in the woods and many children didn’t even own a pair of wellies or a proper raincoat.  I think that this is starting to change now and that parents are spending more time outdoors with their children and taking more of an interest in what’s around them.
What is a typical day like for you…. Or is there such a thing?

There’s really no such thing as a typical day for me.  Over the next month for example I’ll be running energy workshops for primary and secondary school students in Dublin, training primary teachers all over Carlow and running workshops with a school in Kildare who want to study habitats in the school grounds for their Biodiversity flag.  When I’m not out and about, I work mostly from home during the morning when my son is in pre-school and in the evenings after he goes to bed.
I notice you have also started blogging, I really enjoy reading your posts;
How are you enjoying communicating your thoughts and ideas through this medium?

I’ve been meaning to start a blog for ages but only just started a few weeks ago.  I love this kind of writing.  I started an online blogging course with Lorna Sixsmith of We Teach Social and it’s been great.  I’m picking up lots of tips and ideas although I must admit I’m falling a bit behind on my homework lately.  It’s a challenge coming up with ideas and then trying to get them down in a way that hopefully will be of interest to other people but is also fun for me to write but I’m enjoying it so far.  I also enjoy reading other blogs.  I love yours especially and Dee from Greenside Up is always an inspiration.
And the final world….
What is the best thing about what you do?

I love coming up with new ways to introduce people to science and nature and making it relevant to them.  I also love that I can go out for a walk, take photographs and look around and call it work.
What advice would you give to anyone thinking of starting a career in your field?
I think I’m still trying to define what my field is.  Environmental Education is still quite a small area and I certainly never fit well into any of the boxes I’m supposed to tick.  I suppose my advice to others would be to believe in yourself and your message and don’t focus on the things you don’t know but concentrate on what you can teach others and how you can inspire them. 
And what are you hopes for the future of Wildways Adventures?

I’d like to expand my family activities and get more people interested in exploring the outdoors and discovering nature and heritage.  At the moment, many of the families who come to my activities are those who are already going for walks and bringing their children outdoors so I’d like to attract a wider range of families.  I’d also like to work with more community groups, local tourism bodies, accommodation providers and tourist attractions who are interested in promoting family friendly outdoor activities.

Sound waves help the special effects team on Jurassic Park Movie

photo credit: Scott Kinmartin via photopin cc

Most of us have seen the Jurassic park Movies; Do you remember the scene in the first film when the dinosaurs are introduced for the first time? It is a very powerful scene… they are in the jeep and sudden the rear view mirror starts to shake and the water in some drinking cups, sitting in cup holders, starts to vibrate and form circular wave patterns.  I think it is an excellent scene… building up the idea of something big approaching using very simple visual effects. These effects were not simple to achieve however, it seems the special effects department were baffled as to just how to get the exact ripple patterns in the water that they required.

Eventually inspiration struck as Michael Lantieri (special effects department) sat at home strumming a guitar and suddenly noticed the effect the sound was having on a glass of water… it was his Eureka moment.  Next day he took the idea to work and finally they nailed it! They got the water patterns they desired by placing guitar strings under the dashboard and getting someone to pluck the correct string!

Check out the story in this YouTube clip.

This is a really easy experiment to try at home or in your school… all you need is a guitar, a plastic cup and some water.  Place the guitar on a flat surface, half fill the plastic cup with water and sit it on the body of the guitar (i.e. the wider flat part at the base, not directly on the strings) and start plucking away.  With a little bit of experimentation you see ripple patterns form in the water as you pluck the strings.

Move the cup around a little to see if you can get different effects, or try with more or less water in the cup.  Do you find lower or higher sounds give a better result? Does plucking of one particular string work best or how does it compare to plucking them all together?

Have fun with this one and remember to let me know if you try it out at home or in your school.

The Science of Sound

It is National Science Week this week and I am bringing my “Science of Sound” workshop around schools in county Galway for the next two weeks as part of the Galway Science and Technology Festival.  The fun kicked off today in Gaelscoil Mhic Amhlaigh where we learned about sound, had great fun making, feeling and even seeing sound and its effect on some different materials.

You can expect plenty of “sound” posts on the blog for the next few weeks, as I will be sharing lots of experiments, facts and information… but today I thought I would share five fun facts about Sound!

Did you know

photo credit: jvverde via photopin cc
  • … sound waves travel in water at a speed of nearly one mile a second, which is more than four times faster than sound travels through air?
  • … a bat can detect an object as small as a human hair using echolocation?
  • … thunder is the sound made by lightning? Sound travels in air at a speed of almost one mile in five seconds.  If you count the seconds between seeing the lightning and hearing the thunder you can work out the distance from the source of the thunder! For example, if you count ten seconds between the lightning and the thunder then you can tell the storm is about two miles away!
  • … the loud noise created by a cracking whip is due to the fact that the tip of the whip is moving so fast that it breaks the speed of sound?
  • … the scientific study of sound is called acoustics?

More glowing fun…

I told you we were a little “glow crazy” in our house this Halloween season and I promised you one more glowing blog post, so here it is… we decided to give an old favourite… “rainbow explosions” a new twist and made them glow in the dark. This one was so much fun!

You will need:

Small plastic pots or cups
Vinegar
Bread soda
A number of different fluorescent paints (or glow in the dark paints*)
A plate or tray to contain the experiment
A UV light*

What to do:

This is just like the original Rainbow explosion experiment except we used fluorescent paint instead of food colouring and we added the vinegar to the bread soda instead of the other way around!

  • Line up your plastic cups on your tray or plate… one cup for each colour you have.
  • Add half a teaspoon of bread soda to each cup.
  • Add half a teaspoon of your flourescent paint to each cup, a different colour per cup, and mix into the breadsoda.
  • Turn on the UV light, and turn off your main light, and add vinegar to each pot.
  • Watch the “explosion” of glowing rainbows!

*If you do not have a UV light you can try this experiment in daylight as the fluorescent paints will still give a great colour explosion, or you can use different colours of glow in the dark paint and turn off the lights!!

My three Junior Scientists really enjoyed this one!

We loved how all the colours mixed together!

Have fun and HAPPY HALLOWEEN everyone!
