Welcome Scientists!Today:

OOPS: Please turn in your Data and Graph Types practice (yellow half sheet)

DQ: Look at the diagram. Label each letter with the correct name for the state of matter or the process occurring.

States of Matter Simulation

• You have 18 minutes to COMPLETE the simulation.

• (Work hard!)

Mind-Maps• A way to organize ideas and concepts

using images, arrows and words• Shows connections between concepts• Usually organized around a central idea
