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...
This activity introduces students to the idea that crystals 'grow' (crystallize or precipitate) and that minerals or rocks also form this way, providing a very general idea of the nature of magma (molten material that...
In this activity, students will learn the properties of cleavage and fracture (how minerals break when struck with a hammer), and will use these properties as a diagnostic test for identifying minerals. Working in small...
In this activity, students will be introduced to the concept of mineral stoichiometrics (ratios of atoms in a compound) by performing a chemical reaction between copper and sulfur, which can result in either covellite...
In this activity, students construct a magnetometer from a magnet and a spring balance and use it to locate buried objects in a tray. The activity will reinforce the idea that local fluctuations in Earth's magnetic...
