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…
Do you know how to find out how old a tree is? Can you tell if one tree is older than another tree, just by looking at it? Older trees tend to be taller with a wider trunk. How to find out the age of a tree. Try one of these easy methods to find…
Did you know arm span ( also known as wingspan or reach ) is approximately equal to height? How to calculate arm span We tested this against a wall using chalk to mark our reach and then standing next to the wall to see if it matched our height. You should measure from fingertip to…
Today’s activity was unplanned, just something we observed whilst playing with water balloons. We were playing with water balloons, filling them up and getting ready to soak each other and I asked the kids while they were holding them if they thought they would float or sink.

The weather has finally warmed up, and our garden is blooming. As part of our challenge with Actimel, we are trying to grow a whole meal in the garden, learning along the way. Z has been learning about plants at school, so he was very keen to tell his sisters and me about the purpose…
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…
This experiment is a super easy air pressure activity to demonstrate the Bernoulli Principle. What is Bernoulli’s principle? Bernoulli’s principle states that the pressure of a fluid decreases as its velocity increases. Bernoulli Principle Demonstration What you need: A large empty water bottle bottle A rolled-up ball of paper, small enough to sit inside the mouth…
Earthworms are pretty amazing creatures. To celebrate all things earthworm I’ve put together a list of fun earthworm facts and earthworm activities for kids! Earthworm facts How do earthworms move? If you look at an earthworm, you can see its body is made up of many segments. Underneath the segments are muscles that contract and…
Welcome to a new feature on Science Sparks, in collaboration with Inspiration Laboratories and The Imagination Tree. Each month we’ll set a challenge for you to try and then share the results with us! First, we explored how the shape of a building is important for strength. These brittle egg shells are actually quite strong…
Z has been learning about units of weight and measurements in school and has been keen to put what he has learned into practice at home with the girls with this fun weighing and measuring activity. I gave them the kitchen scales and various things to weigh, and Z designed his own table to record the…
