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.
If you eat or drink too quickly, you might find you burp! Burping is how extra gas is expelled from the body. The gas is forced out of the stomach up the oesophagus and out of the mouth! These burping balloons are very easy to set up and great fun to watch. The balloons will…
Human teeth allow us to tear, grind, and crush food into smaller pieces, which we then swallow and digest for energy. Did you know the way your teeth are aligned in your mouth is unique to you? A bit like a fingerprint. Parts of a Tooth Enamel Enamel is the outer layer of the tooth…
This lovely, colourful science experiment is super easy to set up and carry out, but looks amazing! As well as being fun to watch, it’s also great for learning about density ( the oil layer floats on top of the water ) and diffusion ( as the food colouring spreads out through the water layer)….
This very simple science activity is a fun take on a magic opening flowers investigation. It’s also part of my Halloween paper science experiment pack containing five easy paper based activities for Halloween. The idea is to fold the paper ghosts up and watch as they open in the water. This happens because the paper…
Physics is key to understanding the world around us. While some aspects may seem tricky to understand, many fundamental physics concepts can be broken down into simple concepts, some of which can be demonstrated using basic equipment at home. This list of 5 physics experiments you can try at home is a great starting point…

This DIY slingshot is very easy to make and only requires a couple of cardboard tubes, elastic bands and a pencil! When the pom poms are fired out of the launcher they don’t fall straight to the ground, but instead follow a curved path. This is because there are two forces acting on them. Gravity…
The Coriolis Effect refers to how the objects moving on the surface of the Earth appear to follow a curved path due to the rotation of the Earth. It is named after Gaspard Gustave de Coriolis who first described the effect. The Coriolis Effect influences the movement of wind. Wind is moving air caused by…
A Halloween Candy Grabber is a great STEM challenge for Halloween. Children can investigate by making the grabber shorter and longer or adding extra pieces like easy to hold handles or extra grippy bits on the claw part. I added some teeth and an eye to make my grabber look more Halloween like, but you…
Calcium is a mineral needed for strong bones and teeth. Calcium also plays a role in blood clotting, the normal functioning of the heart and is used by nerves and muscles to help us move. This activity using eggs is a very visual way to demonstrate what happens if you don’t have enough calcium in…
