This is a presentation I developed for use with my department when introducing the idea of writing scientific explanations. It focuses on Joseph Krajcik's framework which uses the "evidence-claim-reasoning" approach to developing a well-written scientific explanation. Good for use in professional development with science staff. Note: the experiment mentioned in the presentation was one I used as an example with my teachers during the workshop. This presentation is meant to be used with my E-C-R foldable, also listed on here on TPT.
