If you think you are going to be in my class next year, I would encourage you to go to the online resource page on this site and to visit the Khan Academy where you'll find lots of videos on all of the topics you'll study in the fall. Try the videos on chemistry, physics (forces and motion), astronomy, and density. Once you watch one or two tell me what you think of what you watched. See you in the fall!
Here's where you'll find homework and more!
