Is that a diamond or cubic zirconia on your finger? After Tim and Moby introduce you to the world of mineral identification, you’ll never be fooled again! In this BrainPOP movie, you’ll learn how to use the physical properties of minerals to tell them apart. Discover why it’s important to look not just at color and hardness but also other properties like luster, streak and even something called cleavage! You’ll learn about the different scales used to measure mineral properties, and why the only mineral that can mark up a diamond is another diamond. Soon you’ll be ready to start that rock collection (just don’t leave them in the living room)!
