These super simple investigations are great for demonstrating the surface tension of water. What is surface tension? Surface tension is a force which causes a layer of liquid to behave like an elastic sheet or skin. Water molecules are more attracted to each other than other molecules, as water is a polar molecule. The positive hydrogen end of…
Charles Darwin is known as the father of evolution. He sailed around South America for more than 3 years, before heading to the Galapagos Islands, where the data collected in just five weeks formed a fundamental part of Darwin’s theory of evolution and natural selection. If you’re looking for a great book to use when…

Years and years ago I posted three easy recipes for fake snow. They are still great, but since then we’ve discovered the rather amazing Insta Snow Powder. Insta Snow powder is a super absorbent powder very similar to what is found in babies nappies! Insta Snow powder is slightly different to that in nappies though…

I can’t really take the credit for these awesome animal cell models as it was my son’s science homework earlier in the year, but he did such a good job I wanted to share on here. His first thought was to make a spherical cake model, which I thought sounded a bit tricky, so we…
We first tried painting on a sheet of ice many years ago, but as my littlest loves to paint I set it up last weekend to try with him. I made it slightly different this time by adding string to the top so we could hang our beautiful ice pictures up afterwards and watch what…
This blubber experiment is a simple, easy way to demonstrate how animals ( not just polar bears ) stay warm in cold temperatures. There are some fun polar bear facts at the bottom of the page, too. How many do you already know? The same experiment works for talking about how penguins stay warm in…
