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.
Birds can fly because they have wings, a streamlined body, strong muscles and very light, hollow bones. Birds’ bones are very strong and perfectly adapted for flight. They have a dense, strong exterior and an interior strengthened with criss-crossing ridges and webbing. The hollow interior isn’t just to reduce the weight of the bone. Bird…
A convection current is the movement of a fluid ( such as air or water ) caused by differences in temperature. When part of a liquid or gas is heated, it expands and becomes less dense. The warmer, less dense fluid rises upwards, and the cooler fluid falls to take its place. This cycle of…
It sounds completely counterintuitive, but whether hot water freezes faster than cold water has been debated for centuries. The Mpemba Effect The Mpemba effect is the term used for hot water freezing faster than cold water after a Tanzanian student named Erasto Mpemba found that his mixture of hot milk and sugar froze faster than…
A stacked ball drop demonstration is a brilliant way to demonstrate momentum transfer between objects. The compression of the bigger two balls bounces the smallest ball much higher than it would normally bounce. You’ll need A basketball A tennis ball or small basketball/football Table tennis ball or golf ball Stacked Three Ball Drop Instructions Hold…
If you were to drop a table tennis ball and a basketball, which do you think would hit the ground first? This sporty science activity is an eye-opening demonstration with lots of opportunities for learning and exploration. Sporty Science Ball Drop Investigation You’ll need 4 different balls – for example, table tennis ball, golf ball,…
Wimbledon has started, and tennis fans in the UK have been very excited, so I thought I’d take the opportunity to share some lovely tennis science investigation ideas. These easy activities are brilliant for outdoor learning and work well in a home or school environment. Easy Tennis Themed Science Experiments Tennis Ball Catapult First up…
The colour of an object is the colour it reflects, while other colours are absorbed. White reflects all the colours of the spectrum, while black absorbs all the colours, reflecting very little back. Visible white light from the sun consists of seven colours: red, orange, yellow, green, blue, indigo and violet. When white light hits…
Have you ever wondered why balls bounce? This activity uses differently shaped balls to investigate how and why balls bounce differently. I’ve included FREE instructions for a science investigation to find the bounciest ball with a handy table for recording results. Balls to use: Look at the differently shaped balls and try bouncing them on…
Did you know you can separate salt and pepper with static electricity? It works because pepper is lighter than salt, so while both salt and pepper are attracted to an object charged with static electricity, only the lighter pepper jumps up. Static electricity is the build-up of electrical charge on the surface of an object….
Salt is a brilliant, versatile and inexpensive ingredient for science at home. It can be used to cool a drink or make ice cream quickly, for a lava lamp, and to make coloured salt crystals. Salt is an interesting substance as it lowers the freezing point of water, leading to lots of exciting science experiments!…
