  • Scuba diver

    A Cartesian diver

    An old favourite experiment, the Cartesian diver is easy for students to complete. Explore important ideas that build a foundation of knowledge. 

  • Sea salt crystals

    Chemistry and electricity

    Create coloured writing from acids, alkali, and salt solution, all activated through electrolysis.

  • Spilt ink

    Disappearing ink

    Explore the reaction between acids and bases as students create disappearing ink, in this favourite classroom practical.

  • Lightbulbs

    Electricity from chemicals

    Use various metals, in pairs, and n electrolyte to form a cell. Then observe the formation of ions around the reactive metal, and compare the speed with which they form around the less reactive metal. Includes kit list and safety instructions. 

  • Molecule model

    Experiments with particles

    Predict what will happen to the volume of materials when they are added together… then observe
