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.
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…
Nitrogen is an essential element for living organisms as it’s needed to make proteins for growth and repair and other biological functions. Nitrogen moves through the air, soil and living organisms ( plants, animals and bacteria ) in a process called the Nitrogen Cycle. Where is nitrogen found? In the air as a gas. About…
The Archimedes’ Principle is a scientific law which explains why some objects sink and some objects float. Archimedes was one of the world’s greatest scientists. He was a mathematician, inventor, engineer and astronomer, but is arguably most famous for his Eureka moment which led to the development of the Archimedes’ Principle. Buoyancy and Archimedes Objects…
I’ve lost count of the number of water science experiments we’ve done over the years. Water is pretty amazing. Did you know it is the only natural substance to exist in three physical states at temperatures naturally occurring on Earth? Facts about Water Water has lots of properties that make it just brilliant for simple…
Fresh ice feels sticky because when you touch it, the ice immediately freezes the moisture in your skin, which makes the ice feel sticky to touch! A great way to learn about the properties of ice is to try some ice experiments! When using ice with small children always leave it to melt a little…
Have you ever looked up at the moon and wondered about its pockmarked landscape? Craters are fascinating geological features that give a small insight into the history of our solar system. This is a great ( and very easy ) activity for discovering how craters are made. Did you know the moon’s surface has millions…
Today I have lots of ideas for preschool science experiments to share. Science isn’t just complex experiments for older children. Science is all around us and can be enjoyed and explored by children of all ages. Even just simply encouraging children to touch objects with different textures or observe the world around them is introducing…
