Today, we did our second lab of the week. We played with dried ice, and the purpose of the experiment was to  observe the process of sublimation, which is when a solid turns directly into a gas. Andrew spent the beginning of class showing us how to manage and safely play with the ice, then gave us a few minutes to look over the lab hand out, and the rest of the class time was spent playing with the ice.

  • Work on Unit 2 assignments. If you would like the list of assignments, worksheets, and the criteria for labs, go to the Class Blog on Andrew's DP. You should be able to find Lab 2 on the January 29 post and Lab 1 on the January 28 post (there are two January 28 posts so look through both of them. One post has all the information regarding the lab experiment and the other post has the rest of the assignments).
