In Module three, the math about wave lengths and frequency has us working with dividing scientific notation. I wanted to make sure that I had my math facts correct for that. I thought this video helped sum up the refresher that I needed.

I have been following along on the tests as I've prepared for class to make sure that the material is covered appropriately. For this test, I felt that one of the questions about the Rutherford experiment was not as clear in the text as it could have been. Rutherford discovered protons - this is mentioned in the text prior to his experiment being discussed. The discussion on the experiment focused around protons being in a nucleus. The test question asked about the experiment but didn't mention nucleus only that he discovered protons.
I did contact the publisher and they gave me links to back up that Rutherford discovered protons. I'm not disputing that, I just don't like the wording of the question based on the text that was presented. I will make sure I emphasize in class today that Rutherford's EXPERIMENT is how he discovered protons.

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/
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.
