Lesson Plan - Get It!
This is a mineral known as magnetite. Do notice anything strange — or even crazy — about it? Tiny magnetic filings are sticking to the rock! Do you see them? How and why to they do that?
As you learned in the previous Related Lesson, found in the right-hand sidebar, minerals can be either very hard, very soft, or somewhere in-between.
It is important to know how hard or soft a mineral is when using it in an object or tool because it will affect how the object is used and how it works. So far in this Minerals series, you have seen that you can identify different types of minerals by conducting a streak test to find the color of a mineral's streaks, or a hardness test to see how hard or soft the minerals are. In this lesson, you will be conducting a magnetism test to see which minerals are magnetic!
There are many things in the world that are magnetic, such as a screw, a paperclip, a mailbox, and even a fire hydrant.
- But did you ever think that rocks — more specifically, minerals — could be magnetic, too?
By performing a magnetism test, you will see that minerals can indeed be magnetic. It's time to check in with Flo to see what she has to say about magnetic minerals:
