This database integrates field-based research, teaching, and learning and is intended to make geoscience field guide literature more accessible and useful to users. Features include background information for educators...
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...
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...
