Demonstrate diffusion, density and the particle model to your 14–16 learners in this easy experiment
When teaching 14–16 year-old learners the particle model, experiments can demonstrate the arrangement and motion of particles in solids, liquids and gases, for example, adding food colouring to water. However, this can take time that isn’t available in packed timetables. Thankfully, there are simple alternatives. In this Exhibition chemistry demonstration, chemistry teacher Declan Fleming shows how coloured sweets can provide easy and speedy experiments to help learners grasp the particle model, diffusion and density.
