Today in class we were told there is a chance for extra credit. We can complete a TLC packet that review everything that we have been through step by step. Mr.Paek also introduced us to ChemThink. ChemThink is a website that gives us notes and quizzes us on material we go over in class. We learned about atoms and how they are different in different substances.

ChemThink goes over atoms and molecules. Also it goes over what the atoms and molecules look like in a solid, liquid, and gas.

Solid: Vibrating atoms that stay in their basic position.

Liquid: Atoms that are floating as if they were in water.

Gas: Atoms that are bouncing and flying everywhere under no control.
