Scientific Method Comments

I think this is a really good introduction to scientific methods. The section about caluculating errors shows students that science doesn't have all the answers, but that we can know how confident we should be in our results. This is also shown in the section where students have to measure the diameter of galaxies. There are clearly a few different ways to do this. But which is "the best"? This lab focuses on giving students the tools to deal with scientific issues, but also asks several application and analysis questions which aren't simply correct/false answers.
