Mystery Science
Mystery Science organizes elementary science around questions meant to open discussion and hands-on work.
Lessons are arranged by school grade and cover animal needs, weather, forces, fossils, ecosystems and Earth and space. Each is framed by a question, such as why stars come out at night or what makes a bridge strong. Mini lessons are short, while full lessons pair a video with an activity. The structure is closer to a guided lesson than to browsing clips.
