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.
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…
Have you ever had a static shock from a shopping trolley or an escalator? The shock is because of static electricity, which can cause materials to attract or repel each other. How does static electricity work? Static electricity is what makes your hair stand on end when you rub a balloon on it. Static electricity…
Here at Science Sparks we love a bit of science magic and this leak proof bag is one of the best. My daughter used this for a school talent show when she was just 5 and the rest of the class loved it! How to make a leak proof bag Materials Sharp pencils Plastic sealable…
These super simple investigations are great for demonstrating the surface tension of water. What is surface tension? Surface tension is a force which causes a layer of liquid to behave like an elastic sheet or skin. Water molecules are more attracted to each other than other molecules, as water is a polar molecule. The positive hydrogen end of…
