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.
It’s hard to imagine a life without Wi-Fi and all the benefits it brings, but who invented it? Hedy Lamarr and George Antheil Hedy Lamarr (1914-2000 ) and George Antheil (1900 – 1959 ) invented a system which allowed radio waves to jump onto different frequencies. The idea was originally to stop the US Navy’s…

Today’s science investigation is a fun one! We’re going to waterproof a boot – not a real one, as hopefully your boots are already quite waterproof, but a paper one! The idea is to print off the sheet, colour it in, cover it with different materials and then spray it with water to find out…
You might think butterflies’ brightly coloured wings make them stand out to other animals, but the colours are often a defence mechanism to deter predators! The coloured leaves of butterflies are an adaptation that has evolved over millions of years. Why are butterflies brightly coloured? A warning Bright colours act as a warning to other…
Hooke’s law states that the amount of force applied to an elastic object is proportional to how far it stretches. However, if the object is overstretched it will not spring back. Hooke’s Law only applies if an elastic object is not overstretched. Objects are made from lots of molecules with bonds between them, if too…
The food available to animals varies depending on where they live. In habitats where food is limited, animals with features or adaptations that allow them to access food more easily are likely to survive more successfully than those without the advantage. Animals with adaptations that allow them to live longer are more likely to produce…
This simple investigation is great for learning about stretchy materials. The challenge is to find a material that stretches easily and also returns to its original size. Don’t forget to check out my other ideas for learning about materials and their properties too, including sorting objects from Ariel’s cave, creating a superhero cape and saving…
Sublimation is when a solid becomes a gas without turning into a liquid first. There are three states of matter. Adding or removing energy from a substance can change the state it is in. For example water is a solid below 0oC ( freezing point ), a liquid above 0oC ( melting point ) and…
Toothpick structures are a fantastic, low-cost, and easy STEM challenge that keeps kids busy for hours. We used cocktail sticks, but you could also use straws or spaghetti. I set the children a challenge to build a structure that would hold a chocolate egg off the ground. Toothpick Tower STEM Challenge Toothpick structure materials How…
Transpiration is the loss of water from a plant. Transpiration mainly occurs from the leaves. Water vapour diffuses out of the stomata ( tiny pores mostly found on leaves ). Loss of water from the leaves creates a pull on the water in the xylem cells, drawing water up the plant. This movement of water…
