    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!

    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.
