What is a rock?
(Color/luster) is the property used to tell how shiny or dull a rock is.
What is luster?
A natural material that forms from nonliving matter is a (mineral/soil).
What is mineral?

What is true?
True or False: There are 5 layers of soil.
What is false?
There are 3 layers: topsoil, subsoil, and bedrock.
You can tell rocks apart by looking at their (physical properties/size).
What are physical properties?
This rock is crushed and ground to be used as salt for our food.
What is halite?
True or False: We should not eat minerals.
What is false?
Minerals provide good things for our body!
The mineral (calcium/halite) helps our body to form strong bones.
What is calcium?

What are color, texture, and the minerals it is made of?
(Sedimentary rock/Metamporphic rock) forms when a rock is changed over time by lots of heat and pressure.
What is metamorphic rock?
The mineral (calcium/iron) helps our blood by carrying oxygen to all parts of our body.
