Students should have a log book for their experiment. Use this to record everything: what you do, think, observe, measure, etc. Be sure to date every entry in your log book.
I have suggested that students use the music composition book for this purpose or another spiral notebook.
A summary of week one is due on Tuesday, 1/18. This needs to be one paragraph describing what you did this week. You may also include a drawing to help me understand what you did.
On the grading rubric page, there is also a space for a parent signature. Be sure that this is signed before you turn it in!
