Do you remember our lolly stick races? They are a great way to explore surface tension, but this activity demonstrating surface tension with toothpicks is even easier! The toothpicks start off in a triangle shape and then fly apart when a little washing-up liquid is added. Surface tension activity with toothpicks You’ll need Instructions Why…
On a rainy day, my children can often be found skidding down our hallway. We have wooden floors, so they are slippy enough to be fun, but not so slippy it’s dangerous. We have found that skidding is a lot more fun when wearing socks, but why is this? The answer is Friction. Friction is…
How do you make a lolly stick race across water? Would you believe me if I told you all you needed was a drop of washing-up liquid ( dish soap ) and some water to do a fun surface tension experiment? Racing lolly sticks – surface tension experiment You’ll need Water A large container –…
Do you know you can easily make a homemade wormery? It’s probably not as tricky as you might think, either! A wormery is a great way to observe over time and learn about earthworms, which are very useful animals. What you need to make a wormery How to make a homemade wormery Top tips for…
This was my first attempt at making a cotton reel car, and it didn’t work quite as well as I hoped and definitely didn’t look as good as I wanted, but a cotton reel car is a great little engineering project with lots of possibilities. How to Make a Cotton Reel Car I tied the elastic…
Today, I am very excited and honoured to have the lovely Maggy Woodley guest posting for us. Maggy blogs at Red Ted Art and has a great sound science experiment to show us. Hello! Lovely to be visiting Science Sparks again. I think Science Sparks is doing AMAZING things in getting families and bloggers into…
Z and I have been cycling near our house trying to see how far we could get on our bikes without peddling. We start at the top of a hill and just roll down. Z was curious as to whether we would get further on a steeper hill, so I set us the challenge of…
What do you think the nose is used for? Why do we have a nose? To smell – did you know that the olfactory organ helps us smell odours? To breathe – did you know that 15,000 litres of air are filtered daily? To speak – the nose forms a resonating cavity for the voice…
Today the lovely Maggy is visiting from Red Ted Art with a great activity to introduce the idea of aerodynamics and trajectory to your children. How wonderful to be visiting from Red Ted Art today! It is no secret that I LOVE Science Sparks and all that these wonderful ladies have to offer us. I loved…
The water cycle is an amazing process that we started to talk about when discussing evaporation a couple of weeks ago. In this simple science activity, children make a model of the water cycle to show the process in action. What is the water cycle? Water on Earth is recycled over and over again; it’s…
