So far, we have focused on matters relationship with energy and other substances in the universe. This unit will focus on: What is matter? This unit will focus on: What is matter?

What is matter made up of? This unit will focus on: What is matter? What is matter made up of? How do we categorize matter? This unit will focus on: What is matter?

What is matter made up of? How do we categorize matter? How do different types of matter differ? This unit will focus on: What is matter? What is matter made up of? How do we categorize matter? How do different types of matter differ?

How do different types of matter interact? Etc. What do you remember about matter from grade 8? Review Matter is defined as anything with mass and volume
