Chemical garden
The chemical garden is a well‐established experiment from the chemistry of salts, solubility, diffusion, and solutions. The nice thing is that if metal salts are put in sodium water glass solution, it can lead to an effect reminiscent of plants growing. This growing process can be observed and analysed. In the end, the experiment looks like a wild garden. Students can investigate behaviours of various salts or factors influencing the growth of the crystals such as temperature.
