Mystery Science is a relatively new service that is offering nice science lessons for elementary school students. The lessons on Mystery Science feature a series of videos and images arranged around a science subject. After each video there are questions that students can answer on their own or work through with your guidance. The lessons don't stop there. After the initial videos and questions you can extend the lessons by leading students in hands-on activities that reinforce the concepts shown in the videos. Mystery Science provides materials lists and detailed directions for each hands-on activity.
Applications for Education
Mystery Science lessons are arranged in thematic sets. For example, there is a set of lessons titled Plant Adventures. In Plant Adventures you will find eight lessons tackling questions like do plants eat dirt? You can use the lessons in the sequence in which they're presented or simply pick the ones that best fit your needs.
