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.
Cloud seeding is when tiny particles are added to clouds to help them produce more precipitation. Clouds form from tiny, light water droplets or ice crystals. As they bump into each other, they merge to form larger drops. The water droplets fall as rain when they are too heavy to be supported by upward moving…
Today’s new STEM challenges celebrate all things spring! Here at Science Sparks, we are looking forward to better weather and all the new growth, colour and life that spring brings. Try these easy spring STEM Challenges to get the new season off to a great start. What is Spring? Spring is the season between winter…
Have you ever seen someone flick a tablecloth out from under plates that stay in place? The plates stay in place because of a concept called inertia. A slightly easier way to demonstrate inertia is by dropping an Easter egg ( or other object ) into a container. We usually do this science demonstration with…
Have you ever wondered how far Jupiter is from Mars or Venus from Earth? Our handy calculator makes it easy to find out! All distances are average and approximate, as it’s difficult to be accurate with such large distances. Planets are also at different distances from each other depending on where they are in orbit…
This activity uses Skittles to demonstrate radioactive decay. The rate of decay depends on the isotope of the element and is referred to as the half-life. Radioactive decay is a random process. To understand the concept of a half-life, we’re going to pretend Skittles are radioactive atoms. Skittles that land with the S upwards are…
I can’t believe it’s time for British Science Week again. It seems like two minutes since we planned our space-themed experiments last year. If, like me, time has run away from you and you need some easy ideas for British Science Week, we’ve got some suggestions that might help. Change and Adapt Activities Birds, Beaks and Charles Darwin Learn…
A singing balloon experiment is a great way to learn how sound works. If you put a small coin inside a balloon and spin it, the coin spins around the balloon, making the balloon vibrate very quickly. Objects that vibrate quickly make a high pitched sound. As the coin slows down, the pitch of the…
I usually do this viscosity experiment using different liquids such as water, oil, ketchup and treacle. This version is a special syrup filled investigation for pancake day! The idea is that you record how long it takes different delicious pancake syrups to flow down a ramp. Thicker ( more viscous ) liquids will flow more…
Good science kits can be hard to find, but you’ll never be disappointed with MEL Science. Each kit contains everything you need to carry out a hands-on science activity or experiment safely at home. The instructions are easy to follow and presented in a fun and engaging way and extra videos and associated app are…
