WHAT IS A MINERAL?

A naturally

occurring solid,

made up of

elements

WHAT IS THE DIFFERENCE BETWEEN AN ELEMENT AND A

MINERAL?

WOULD THE PHYSICAL PROPERTIES OF MINERALS BE DIFFERENT THAN THE PHYSICAL PROPERTIES WE USED TO

STUDY THE ELEMENTS?

PHYS ICAL PROPERT IES OF MINERALS

Each person will be assigned a paragraph to

read in their group.

Read & Write Down the most important

information on the handout.

With your tablemates create a T-Chart to list all

important information for each topic.
