From the Centre for Science Education, and with support from Shell Education services, these materials help children to grow large crystals using salt solution. The crystals take about a week to grow. This activity gives children the opportunity to consider processes such as: * changing materials and that changes occur when materials are mixed, heated or cooled * crystallisation * reversible changes including dissolving and evaporating Teacher guidance gives information on the materials required, scientific context and an outline of the activity.
