Apologia Chemistry 3rd Edition - Note 1

This year I'm leading Chemistry at our co-op. We chose Exploring Creation through Chemistry 3rd Edition.

I have 100 minutes with my students once a week. The goal is to work on a module for two weeks together in class.

This week is our 5th meeting which means we are on week one of module 3.

(I lead Chemistry at our co-op two years ago. We used the 2nd Edition that year and we only had 50 minutes together.)

The students take tests at home, they grade at home and their parents assign the grades. I am helping to facilitate some lecture and provide a time to do the experiments together.

For the first test, most of the students did very poorly on the test including my very mathy child. The material wasn't that hard, but you definitely had to pay attention to the details. Those significant digit rules were followed to a T and probably even a little too far in my opinion. https://www.apologia.com/faqs/content/10/186/en-us/on-chemistry-module-1-test-problem-17-why-is-the-answer-rounded-to-the-tens-place.html 

As I was preparing my lecture notes for module three, I had the test open as well. I'm going to ask the publisher about question 12 on the module 13 test. The answer isn't directly stated in the text as simplistically as the question is asked.
