What We Did Today
We continued our work on drawing models of molecular motion. We started class by discussing how a thermometer works by using what we learned yesterday. Check out the animation if you were absent. http://www.middleschoolchemistry.com/multimedia/chapter1/lesson3#heating_and_cooling_a_thermometer
Our focus today was on molecular motion of solids. We did completed "Moving Molecules in a Solid". If you were absent, you can get the lab sheet from science files and click on the following link to complete the activity at home. http://www.middleschoolchemistry.com/multimedia/chapter1/lesson4
Homework
Make sure you have answered all of the questions in our last two labs. Ask your parents if they could think of things in your home that require expansion joints.
