Science Sparks is full of easy and fun science experiments for kids to do at home. Our fun science investigations include engineering, coding, biology, chemistry and physics experiments.
Learn more about the wonderful world of science by trying our exciting science experiments, cool facts, free printables, photos and videos. We’ve also got a great collection of STEM projects, STEM Challenges and science fair projects.
Our science experiments include removing the shell from an egg, launching bottle rockets, create edible life cycles, making lava lamps and lots more science experiments for kids of all ages.
I remember the first time I saw a centrifuge in a lab and thinking how clever it was. Centrifuges can be used to separate mixtures, by spinning them at very high speeds. Liquids that are more dense settle at the bottom of a test tube after spinning. A washing machine spinning is also an example…
Marie Daly was an American biochemist and the first African-American woman to receive a Chemistry PhD in the United States. Marie’s groundbreaking work led to a new understanding of how diet affects the human circulatory system. Marie was fascinated by the human body. After her PhD, she worked on a seven-year research program on how…
Welcome to the first post in a new series about inspirational women scientists. Throughout history, women have made huge contributions to science, technology, engineering, and maths but have often been overlooked. I’m going to highlight just a few of these pioneering women and share some simple science ideas related to their work. The first scientist…
Baking soda experiments or activities are a great, safe and easy way to introduce the concept of a chemical reaction to children. Baking soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide ( a gas ) and water. The fizz produced is brilliant fun for children to watch, especially if you combine it…
This activity is a bit tricky and possibly very messy, but also a fun way to learn about density. Adding salt to water increases its density, so the less dense plain water sits on top. The two don’t mix. What you need Salt Water Density Trick Instructions Why doesn’t the water mix? The salty water…
Magicubes are brilliant magnetic cubes that can be used for free play or in the case of this set, learning to read and recognise words. The cubes feel like great quality and although my 3 year old is not at the stage of reading words yet, he has very much enjoyed free building with the…
We’ve looked at how objects absorb water before using sponges, underpants and even the good old walking water experiment. Today, we’re conducting an absorbing experiment with a twist, aiming to halt the process and investigate which materials absorb water and which don’t. Sugar cubes work well as they absorb water quickly, and if you add…
The summer holidays are a great time to get outdoors and try some science experiments and investigations. I’ve chosen some of my favourite summer science experiments to keep the kids busy all summer long! Science experiments are great for improving critical thinking, teamwork, communication and stimulating creativity. Science experiments in summer can be used to…
We’ve had a Makey Makey for years now and never really moved beyond the banana piano ( which is very cool) so I thought lockdown would be a great time to try something a little more adventurous. Our giant Operation game was great fun and a brilliant second project to try. Makey Makey Operation Game…
When you stretch an elastic band with your fingers it uses energy. That energy isn’t lost, it is stored in the elastic band. When you release the pressure on the elastic band the energy is released and the band shrinks back to its original size. Cotton reel cars are a great example of using this…
