We find lots of lovely flora and fauna on our little adventure in the bog yesterday, this was one of them and the children thought it would make a good Mystery Creature…. can you name it?
Science, Curiosity and Life
Science Wows is all about sparking children’s natural interests in Science!
It is learning while having fun!Whatever the event, whatever the venue it is Hands-on Science for children. Party entertainment, school visits, fun days, corporate events …. there are even local science camps during school holidays.

That is (apparently) one of Einstein’s many quotes. It took me a while to realise just how true these words are, but once I did I was able to marry a love of writing with a love of science. I discovered that once I broke things down to their most simple components

We spent the last day of the Easter Holidays enjoying the great outdoors right on our doorstep.
We are lucky enough to have a lovely two mile long lane into the bog right beside our house, so we decided to take advantage of it and headed for a family adventure in the lovely sunshine.
We drove to the end of the lane and then walked along by the stream in search of a little waterfall we hear was nearby.
Of course there was a picnic (as all true adventurers need food). Plenty of sandwiches and a left over Easter egg for that extra treat!
We didn’t find the waterfall but we did find lots of other treasures.
Why go around the muddy puddles when you can go through them… especially when wearing sandals?
It is a long way back to the car, especially when you are only four and a half.
Do you like
green eggs and ham
I do not like them,
Sam-I-am.
I do not like
green eggs and ham.
I am sure this would suffice as an add on to the coloured egg experiment post but we had so much fun with this I felt it deserved a post all to itself!
We repeated the experiment but this time on two eggs, one of which we coloured red as before and the other one we coloured green… because the children (especially the BIG ones) couldn’t let it go without trying to make “green eggs” and ham!
The first day we dissolved the shell away in vinegar and then yesterday we transferred the eggs a cup of coloured water and left them overnight. We had the fun of checking them out when we got up this morning… and they didn’t disappoint!
The colouring step definitely worked, but we still wanted to cook a coloured egg.
We snipped the membrane of the green egg and scrambled it, and finally we had our “green eggs and ham“!
Doesn’t look too appetizing, does it? But I persuaded the Science Wows team to try it out…
And how does it taste?…
I would not eat green eggs and ham.
I do not like them, Sam-I-am.
This egg experiment is a new take on an old favourite. We have made bouncy eggs before, we even made them fluorescent! This year we decided to add more colour.
This is a really simple experiment, you probably have everything you need already in your kitchen and it is guaranteed to entertain both the young and the young at heart!
Clear malt vinegar, a glass or cup, a whole raw egg, food colouring
Place the raw egg in the glass and cover with vinegar, making sure the egg is completely covered.
Leave overnight or up to 48 hours if necessary.
After this time, remove the egg carefully and rinse it in a bowl of water.
The vinegar will have dissolved all the shell of the egg, leaving just the egg membrane keeping the structure together. The “naked” egg will be soft and bouncy and a little delicate so do be carefully when washing any remaining shell off.
Next place the egg into an empty glass and cover with water, add at least two teaspoons of your chosen food colouring (we used red here) and leave overnight again.
The next day carefully remove the egg from the coloured water, rinse and pat dry (you may find your fingers will get a little stained from the food colouring but it will wash off).
Now you have a coloured, bouncy egg, but be carefully when you bouncy it…
When the egg is in the vinegar you will notice some bubbles forming and eventually a foam will appear at the surface of the vinegar. The eggshell is made up of calcium carbonate. The vinegar (an acid) reacts with the calcium carbonate (a base) producing a salt and a gas called carbon dioxide (these are the bubbles you see). The vinegar will keep reacting with the calcium carbonate until it is all gone, leaving the egg contained in just the cell membrane.
A delicate, but bouncy egg.
When the egg is then placed in coloured water the water will travel into the egg by a process called osmosis. The egg will swell a little with the extra water.
It is International Earth Day today.
I have been thinking of the Earth a lot lately, even more than usual.
Global warming, endangered species, renewable energy have all been in the news lately, and well they should be.
But that’s not what I am thinking about.
I am thinking about plastic!
In fact I am thinking about plastic so much I am trying to think about anything else!
But I can’t!
My ten year old daughter did a project on plastic for school recently.
Here are just some of the facts she shared with her class…
Plastic takes 500 to 1000 years to degrade.
It has been estimated that over ONE TRILLION plastic bags are used worldwide EACH YEAR and only 0.5% to 3% of all these bags are recycled.
In 2006, the United Nations found that each square mile of the ocean has 46,000 pieces of plastic in it.
Over 100,000 mammals are suspected of dying due to plastic pollution every year, on both land and in our oceans.
Marine trash, mainly plastic, is also killing more than a million seabirds each year.
But it is not so bad, right? We can recycle the plastic we use!
Unfortunately not!
My obsession has run to reading all the fine print and checking the recycle symbols of the packaging we use everyday.
Supermarket shopping has become a major stress… it is not enough that it is Irish, locally grown or organic… the plastic it comes in cannot go in my recycle bin!
The more I look, the more I see…. and I wish I didn’t! I wish I could go back to a previous state of ignorance, but I can’t!
It is driving me mad.
So what will I do? Little old me, what can I change… and what difference will it make?
I am not sure what difference it will make, but I have to do something. I may rant and rave here from time to time but I am not a big activist.
So I am going to start off small.
One piece of plastic at a time!
I am going to bring a cloth bag for my vegetable.
I will change to choosing loose vegetable whenever possible and they will go into my cloth bag, not a little plastic one that is on offer for such purposes!
I will choose more farmers markets, where loose produce are more readily available.
I will join a local scheme that delivers a selection of in-season fruit and vegetable to my door each week. It may cost a little more but if I cook wisely I can make these go further.
I can grow more vegetables in my own garden.
Small changes I know, but often small things can lead to BIG changes… so I will keep reminding myself of the Butterfly Effect theory, every time I eliminate one plastic bag from the shopping trolley!
We are spending a lovely few days away as we visit Grandparents and the children get to catch up with cousins. After a long chocolate and fun filled day, some very happy children went to bed declaring “That was the best Easter Egg Hunt ever” …
We chose seven hiding places around the garden and prepared seven rhyming clues for the children to work out where each stash was hidden.
And the best bit of all was the personalised mini mug by Colorines Wonderful for each child! A real treasure!
The lawn mowers are out, leaves are appearing on trees and all things green are starting to emerge…. including the nettles; but don’t despair, when you look at them change your thoughts from annoying, stinging weed to… nettle pesto!
Young nettles are great as a diuretic, a natural anti-inflammatory (used for allergies, asthma, rheumatism) and to treat high blood pressure… to name but a few benefits!
Last year we decided to put all this natural goodness to some use and tested some nettle pesto recipes, tweaking the ingredients to what we had to hand, and what flavours we preferred. Here I revisit an old blog and share our preferred recipe.
First up…. harvest your nettles, even better if you can recruit a helper or two, this was my “helper” for the task – gloves, hat and all!
Wearing our nettle protecting gloves we headed out into the back garden and collected a large basin full of lovely nettles (harvesting the top two to three bracts)…
Next I removed the leaves and washed them, ending up with a colander full!
Next step was to blanch the nettle leaves, so they were added to a large pot of boiling water for two minutes then removed with a slotted spoon and added to iced water.
Then I placed all the nettles into a clean tea towel and squeeze out the water until the nettles were fairly dry
This left me with 100 g nettles, I was ready to make my pesto!
My ingredients…
100 g preped nettles
50 g pinenuts
Juice and zest of one lemon
150 mls olive oil
30 g parmesan cheese
1 clove of garlic
Sea salt to taste
Pepper to taste
All that remained was to add all the ingredients together and blend, blitz or pound them to the preferred consistency.
I got about 250 g of pesto from this, nicely filling four 150 ml bottles…
This pesto goes really well with plain old pasta, or just spread on nice crusty bread. It makes a lovely homemade gift too… just be sure to keep a jar for yourself!

Last week’s Mystery Creature was the Potoo, in this case the Common Potoo (Nyctibius griseus). Here are some interesting facts about this very unusual bird:
Potoos can be found in Central and South America, although fossil finds dating back to the Oligocene and Eocene suggest ancestors of these birds were once also found in France and Germany.
Potoos make some very unusual sounds. As thy need to communicate through a vast habitat they need a noise that can travel. Each species makes a unique call: The common Potoo, for example makes a series of mournful whistle type noises that deepen with each call. Legend has it that this sound is a mournful lament for a lost love – the moon.
Potoos are nocturnal animals. As they spend their days perched on trees and branch stumps they need some effective camouflage. Their elaborate plumage helps them blend in with their arboreal surroundings. Once the Potoo is perched it is very hard to spot as blends into the bark of the tree or takes on the appearance of a branch stump.
Potoos usually mate for life.
Potoos do not build nests; instead they will lay a single, spotted egg in the stump of a branch or appropriate nook on a tree.
Both parents will guard the egg and tend to the hatchling.
Potoos have small beaks but very broad mouths, helpful for catching insects such as moths and beetles while in flight.
An interesting feature of the Potoo is that it can still see even when it closes its eyes… a useful feature when relying on camouflage for protection. Their eye lids have little kinks to allow them a discrete peep-hole view of their surroundings.
In this short video clip Sir David Attenborough gets up close with one of these elusive birds.
Are your children just starting their mid term break? Looking for some exciting activities to entertain them over the next two weeks? How about some Eggsellent Eggsperiments to keep everyone happy?
Here are five of our favourite experiments for Easter… or any other time of the year.
Take this one step further….
We mentioned in the video that you can take this experiment a step further.
Float the egg in the salty water as before.
Add a few drops of food colouring to a jug of unsalted water.
Carefully pour this coloured water down the side of the glass so that it sits on top of the salty water.
The egg will sit between the two layers… can you see it in this picture?
The junior science team were a little enthusiastic
with their salt levels in this video
but you can get this to work with A LOT less salt.
Not only did we make a bouncy egg, but we also made a fluorescent one…. check out these experiments here.
There will be plenty of great Easter blog posts by fellow Irish Parenting Bloggers over the next week or two…. here are a few already posted and if you check back I will keep this list updated as new posts are available.

My four year old decided to join me in the room this morning, while I dressed.
Immediately my ego was on high alert! This guy doesn’t hold back with his critiques.
“What are you doing Mammy?”
“Getting dressed”
“Are you going to wear THAT dress?”
“Yes! Yes I am!” (starting to get very tense now)
“Can I jump on the bed?” (He is already in full flight, don’t know why he bothered to ask!)
“No”
“This isn’t really jumping you know?” … gives a good demo of dive bombing across the bed!
“Are they some kind of trousers?”
“No, they’re tights”… No one should ever have an audience when putting on tights!
“Can you walk in those?”
“Yes, funnily enough, I can!”
“Mum?…”
“Yeees???” Steeling myself for what follows….you have a WOBBLY tummy, your bum is VERY big... or maybe…
I think you are getting FAT!
Eventually… and with much reluctance, I meet his gaze…
His face breaks into an unexpected smile.
“….I love you” he says simply.
My heart melts.
With those three little words I know….it is going to be a VERY good day!
