Classification of Matter
Objectives: Students will...
... classify different types of matter within our world using element, compounds, mixtures, atoms, and pure substances
... investigate and discern different examples of matter with peer review and collaboration

What is matter? What are some different ways we might be able to classify matter? You may draw a picture if you like.

BEFORE YOU GET STARTED... Introduce yourselves to your new group!  Share your name and your favorite holiday.
Then, find your new:
Reader - Reads text out loud
Manager - Ensures everyone in the group is on the same question (is also timekeeper in groups of three)
Spokesperson - Shares screen if need be, is ready to share answers with the whole class
Timekeeper - Makes sure you all get back to the main group on time

Focus Question: How do atoms combine to make different types of matter?

Why?
Look at the things in the room. They are all matter. Matter may be a pure substance or it may be a mixture. Can you tell by looking at it? What if you looked under a microscope? Then could you tell? Something that looks pure may not really be pure. It depends on what type of particles an object or substance is mde of. In this activity we will explore how the smallest chemical units of matter determine whether something is classified as an element, a compound, or a mixture.

As a group, examine Model 1 below. 

Use the diagrams in Model 1 to answer questions 2-13.

Using your answers for 4-5, come up with your own definition for the word "particle."
