    Making your own play dough is one of the simplest science experiments out there. It’s all about chemical reactions! The ingredients come together create a mixture, where they’re physically combined but no reaction has happened. When the water and food colouring are added though, the mix forms a solution. Then the solution is heaped together and kneaded, which then forms a whole new substance because chemical reactions have taken place. How exciting!

    A volcanic eruption

    This classic experiment will have your kids erupt with excitement, whilst teaching them all about the fascinating world of volcanoes.

Just be sure that children are supervised and standing a safe distance away when the action happens.

    Dip-dying fabric is a great way to learn all about molecules and bones, as the dye bonds with the cotton on your fabric and actually becomes – or “bonds with” – the material. It will also teach your little one exactly why getting permanent pen marks out of ANYTHING is so difficult.
