DWU #2- Define the following: Element, atom, molecule, compound, mixture, pure substance, solution.
We went over homework, then took a homework quiz. I gave about 25 minutes to finish collecting data for the lab and begin calculations. We finished the period with a brief discussion of Physical/Chemical changes and some demonstrations. The last 20 minutes of the period was spent classifying substances as elements, compounds and mixtures.
HW: Finish All Mixed Up and E/C/M
