Help Teaching: Online Self-Pace Science Lesssons

The collection of science lessons is designed to cover key concepts and skills in the areas of astronomy, biology, chemistry, physics, earth science, and scientific practices.  Many of the lessons contain a short introduction, followed by an embedded video created by Help Teaching team or obtained with permission from sources, such as Khan Academy,, and Bozeman Science and links to other free online resources to help students understand the topic. Lessons without a video source noted are text and image-based, similar to what students would find in a textbook. All lessons also include practice questions to use for pre-assessment and practice, as well as links to longer, more formal tests and worksheets to assess what students have learned.
