Week 6 Geology Warm ups

Monday Oct 8

1. What are the four characteristics of minerals ( 2.1)

2. What is the most common group of minerals? What percentage of Earth’s crust do they make up?

Today’s agenda:

•Chapter 2/3 pretest

•“Investigating crystal shape”

Objectives:

To understand the minerals are the basic building

blocks of Earth

Investigate Crystal Shape

1. Read CRYSTAL STRUCTURE and Investigate Crystal Shape from page 46. Look at the procedure, materials and the questions at the end. I will be doing this lab as a demonstration.

2. Write a hypothesis for the experiment (remember the 3 words!)

3. Identify the manipulated and responding variables.
