We went over the questions from the activity about solids.
Students then took a quiz over sections 3 and 4. The read about gases when they were finished.
We then discussed the molecular motion of gases using two demonstrations:
1) balloon and balance (teacher-led)
2) soap bubble (group in lab)
We finished by going over the goals and explaining what we saw about them:
Based on observations of demonstrations and their own experimentation, students will be able to describe gas as matter.
Students will also be able to describe, on the molecular level, the effect of heating and cooling on the motion of molecules of a gas.
Test will be next Wednesday.
