Earth Science
Current Unit - Welcome to Junior High!!
Remember to be successful in Junior High, you must be able to budget your time!! 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. Make sure you watch the video tutorials for these units, they seem to help.
