Rocks
This video is a very visual look at the different types and formation of the three groups of rocks.
Minerals
The video introduces mineral properties using common fruit and vegetables as analogies for these five descriptive criteria. The video also demonstrates the orderly crystalline structure of halite (NaCl) using a model made of food (marshmallows and grapes). Comparisons between common substances such as ice and glass versus the mineral definition are made to illustrate the specific nature of the mineral definition.
