Week One Summer 2010 Shortcourse : Math in Science Context: Assignment Questions Post Answers: "Questions for Wed: These are some questions regarding density that could go on the blog. 1. Did the true value for density fall within the ..."
After wondering what the heck we did and if we had the correct metal we found out we were given zinc. Our density average was 7. Our confidence level fell within the proper range since Zinc's density is 7.14.
Our interval changes slightly as the percent increases. The 90% was 7.3 or -6.7 and the 95% was 7.4 or -6.6. I think this would be difficult to explain to my level of students.
As for graphical approach I think that it would be much easier for students to understand the image infront of them rather than a data table. The errors would be more visible in a graphical representation.
As stated earlier I thought a constant light of a movie projector or laser light would possibly not give an inverse square drop off. We found our bulb to 3.44 lumens.
I use wikis, excel, and animoto with my students. I am thinking about using a blog with my students this year but I don't think they will follow it very well, but they might surprise me. I allow students to use different forms of technology so they can express or explain themselves in a 21st century form
