Creating a Crystal Forest

Creating a Crystal Forest

This demonstration reinforces the concept that minerals can form even at low temperatures, meaning that these processes can occur at or near Earth's surface. Using 'water glass' (sodium silicate nanahydrate) and any of a variety of metal salts, the teacher can grow crystals of silicate at room temperature in a container as the students watch and record their observations. A student worksheet and discussion questions are provided.
