Students got back their week #3 news articles from yesterday. We reviewed the conclusion questions from the metric measurements lab. We discussed section 1-3 notes on density. I used a "poly-density tube" as a visual demonstration of density, and I showed students some helpful links on the Moodle site. Before beginning the new lab on page 1-13 & 1-14, I gave students a replacement copy of the lab. The lab calls for students to measure the mass & volume of three unknown liquids (colored blue, green & red) in order to calculate their densities. They then had to compare their calculated densities to a supplied list of known densities of common liquids.
No homework was assigned, and the Chapter 1 test is one week from tomorrow, on September 28th.
