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.
Your skin is a barrier from harmful things in the environment. When skin becomes damaged blood quickly clots ( thanks to platelets in the blood ) around the damaged area to form a dry crust, called a scab. This protects your body from any nasties which could take advantage of the new opening in your…
I can’t take the credit for this one as my 9 year old made it in school last year, but it’s just too good not to have on Science Sparks. I love that it’s more than just a circuit. One of my daughters made a long torch and the other a head torch. Both are…
Respiration is a chemical reaction that is fundamental to all living things. It happens in every cell of every plant and animal. Respiration is the reaction between glucose (from food) and oxygen in the air you breathe. It produces carbon dioxide and water (waste products) and ENERGY! Energy is needed for movement, growth and repair…
Weight and Mass can be very confusing and people often use them interchangeably without really thinking about which is correct, but very simply: Mass is a measure of how much matter an object is made up of. Mass remains constant. The mass of an object on the moon ( or anywhere in the universe )…

From the bright full moon to the tiny sliver of a crescent in the night sky, lunar phases have fascinated humanity for millennia. This activity unravels the science behind the phases of the moon with some simple moon phase cupcakes. Cupcakes are a wonderfully visual representation of how the shape of the moon changes in…
Now summer seems to finally be here, we thought we’d get the sand table out and start playing. We tried to make sandcastles with the dry sand, which didn’t work at all. They just collapsed. Can you think why this is? What could you add to make the sand more ‘sticky’? We added a little…
Today we are looking at filtering and how it can be used to clean dirty water. This water filter science project is very simplified but gives kids a great overview of how water purification is carried out to give us lovely clean drinking water. Do not drink the water in the activity Water Filter Science…
Our Moon is the largest moon in the Solar System relative to its parent planet. It’s thought to have been created about 4.5 billion years ago when an object a similar size to Mars called Theia crashed into Earth. The impact melted part of the Earth’s rocky mantle, which together with debris from Theia was…
Greenhouse gases are gases in the Earth’s atmosphere which trap heat. An increase in greenhouse gases caused by human activity is responsible for the greenhouse effect and global warming. Think how it feels when you enter a greenhouse or when you sit in a room with lots of windows on a hot day. It feels…
