What would happen if the Earth’s gravity suddenly disappeared?
This was a recent question from my 10-year-old son… it certainly got some interesting discussions going around the kitchen table. When I opened up the question
We are used to seeing them at some stage of their life cycle, most of us remember watching them grow as tadpoles in our classrooms, and they are a common part of our ecosystem; but how much do you really know about these diverse and amazing creatures
Toxin, venom and poison… are they just different words for the same thing? The answer is… sometimes yes, and sometimes no.
You see a venom can be a toxin, which can be a poison but not
Even with the extra day the month has flown by. The year is off to a flying start … here are some of the big stories from the world of science that surfaced this month:
Have you spotted Jupiter in our lovely clear skies this week? It is very bright and visible to the naked eye. We got the kids out of bed at nine O’ clock last night just to have a look (they may have been more interested in running around in
I am very excited to share this latest project with you; this is an idea I have had for a while so I am delighted to have finally finished and published. I really hope you like it and that your junior scientists get plenty of entertainment from this
I can’t believe that January is over already, 2016 is well underway. Here are just a few stories that made the science headlines this month:
- Planet Nine is a hot topic this month… NASA remains cautious and sceptical but others are very excited and on high alert. Some are even predicting if we could live there.

- And for some really BIG news, the biggest dinosaur fossil ever found, a Titanosaur, was unveiled at the American Museum of National History. For many of us not lucky enough to be able to attend in person, we got to see this spectacular species through our tv screens, documented by the wonderful Sir David Attenborough.
- For the first time in 11 years, five planets have aligned in the morning skies: Mercury, Venus, Mars, Jupiter and Saturn; Visible to the naked eye under the right conditions.
- The preying mantis got some funky 3D glasses and its own cinema, all in the name of science.
- British astronaut, Tim Peake made history as he became the first UK representative to perform a space walk. He even tweeted a space walk selfie.
I wonder what stories will unfold in February. Do you have any favourite science
Dr. Simple is back answering some more great questions; this one came in from five-year-old Cathal, who can sometimes be found over at the lovely blog Bumbles of Rice.
Cathal wants to know…
Why do we burp?
And here is what Dr. Simple has to say
We have had a lot of fun with this little Christmas science experiment. It is so simple, it is definitely worth a try if you have a few minutes to spare and want to give the kids a good laugh.
Here is what you will need:
- A small jar, or similar, decorated as a snowman. We covered ours in modeling clay and painted it but you could get the kids to paint a jar or decorate it as they wish. (The jar I used here is 100ml volume but you can alter the size.)
- Some water (I used 40mls)
- Washing up liquid (I added about a tablespoon)
- Baking soda (also know as bread soda or sodium bicarbonate, but NOT baking powder… they are quite different)
- A teaspoon.
- Something to stir with
- White malt vinegar (I used 40mls)
Here is what you do:
- First add the water and then the washing up liquid.
- Next add a heaped teaspoon of baking soda.
- Give it a good stir.
- Add all the vinegar, quickly, stand back and watch’s the poor snowman’s brains explode… that’s got to hurt!
- And once your poor snowman has recovered, you can give him a quick rinse and do it all over again!
The Science bit:
I don’t know what meal times are like in other homes, but in ours they tend to be chaotic and unpredictable. Take a simple breakfast last week as an example. Nothing too fancy… there was literally only cereal on offer. But cereal boxes can be great
