Physical Science
8th Graders, be the leaders I know you can be!
Physical Science is broken into 3 main units: Astronomy, Chemistry and Physics. The best advice I can give to you is to budget your time properly, don't wait until the last minute (the night before) to get your work done. Coordinate all your classes and the homework required. It will be easy to fall behind and difficult to catch up. Work hard, stay on top of your assignments.
