The iodine clock reaction investigates how mixtures at different temperatures and concentrations influence the rate at which two components combine.
A very easy experiment to create hard shapes simply by curdling milk with ethanoic acid.
An edible sweet science experiment! The idea is to grow your own sugar crystals by dissolving sugar in warm water and leaving it to cool.
Some chemical reactions give out heat energy, others need extra to work. Observe changes in temperature that happen with experiments and learn about exothermic and endothermic reactions.
A simple activity illustrating the breaking down of colours by bleach by turning coloured solutions into colourless ones.
