  Lesson Plan: Chemistry Basics Unit Plan Mark as Favorite (39 Favorites)

  The AACT High School Classroom Resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We searched through our resource library and constructed a unit plan for introducing the basic chemistry concepts to students: Laboratory Safety, Equipment, and Reports, Periodic Table Basics, Physical and Chemical Properties and Changes, Endothermic and Exothermic Changes, and Classification of Matter. These topics are very important for your students to master before they dig into other chemistry concepts. This unit is designed to be used at beginning of the school year.
