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.
Freezing point depression occurs when a substance lowers the freezing point of another substance. One example is adding salt to water. A solution of salt and water has a lower freezing point than water alone. Melting and freezing: a recap Melting is when a solid turns into a liquid. The temperature at which a solid…
This science experiment using ice and salt is a fantastic demonstration of why salt is used to de-ice roads. It’s also a fun science magic trick! When salt is spread on the road in winter, it dissolves in water on the surface and lowers the freezing point of the water. This means the outside temperature…
A magnet is an object that produces an invisible magnetic field. A magnetic field is an area where magnetic materials experience a force. Objects attracted to a magnet are either a magnet themselves or are made from a magnetic material. The magnetic force in a magnet flows from the north to the south pole, which…
This fantastic and easy demonstration of gravity and magnetism will impress kids of all ages. The paperclip doesn’t fall because it is attracted to the magnet and doesn’t jump up to the magnet as it is held in place by string, making it look like it is defying gravity and floating in the air!! If…
A steady hand game is a brilliant mini electricity or design project and great for working on hand-eye coordination too! I made a reindeer themed game just before Christmas, but you can twist the copper wire into any shape you want. If this isn’t quite what you’re looking for I have lots more simple electricity…
This easy magic milk science investigation is fantastic fun for kids of all ages. All you need is whole milk, food colouring and a little dish soap to create crazy colour explosions. Older children can use this activity to learn about emulsions. The reaction that gives the colourful display is between the fat molecules in the…
Creating a 3D neurone ( or neuron ) model is a great way to learn about the central nervous system and how messages are transmitted around the body. 3D neurone models are also a fantastic addition to a school science fair project about the nervous system. What are neurones? Neurones ( often called nerve cells…
Do you know how to make a lava lamp? DIY lava lamps are one of our favourite science experiments as they are super simple to make, can be used over and over again, and you can be as creative as you like with them. We’ve made Minions, reindeer and even snowmen lava lamps! Lava lamps…
Do you know you can make a pH indicator with the red leaves from a poinsettia plant? Red poinsettia leaves contain anthocyanins which change colour in the presence of acids or alkalis. Acids have a low pH ( below 7 ), and alkalis have a high pH ( over 7 ). If it’s not the…
Mexico is the next country in our trip around the World in 50 experiments. Mexico is located in North America and shares a border with the United States. It’s the 14th largest country in the World. Mexico is very hot, with deserts in the north, mountains and canyons in the centre and rainforests in the…
