First, you will need to download the Rockin’ Good Time lab manual, which can be found here:

Minerals, igneous, metamorphous, and sedimentary. What do these words have in common? They all make up the basis of what we know as rocks!

Rocks provide the foundation for this planet we call home! We see them everyday in our lives. We may even eat them! Okay, we don’t eat rocks. But we do eat some of the minerals that make up these rocks.

We can differentiate between types of rocks based on their physical properties. Explore the different types of rocks and their properties with us in this episode as we create edible rock models.

What is the most abundant mineral on Earth? Well, that would depend on how deep you want to go! Bridgmanite is composed of magnesium, iron, and silicon-dioxide and is said to be the most abundant mineral according to Forbes. We will never see bridgmanite on the Earths surface, however. This stuff helps construct the Earth’s mantle, which is present below the crust we walk upon. In total, bridgmanite makes up roughly 38% of the Earths total volume! That’s a whole lot of bridgmanite…
