1.) color

2.) size

3.) shape

4.) texture

5.) flexibility

6.) luster

What is luster?What is luster?

Luster is how an object shines in the light. A gold ring has luster. A

piece of notebook paper does not.

These pearls have luster.

What is volume?What is volume?

Volume is how much space an object takes up.

Remember: Mass is how much matter is in an object.
