I selected force and motion as my content are of investigation. The first noteworthy site I encountered on my search was Motion and Forces for grades 5-8. This site offers 18 interactive activities on this subject matter. Topics range from simple machines to two dimensional collisions. Teach Junkie is a collaborative effort of teachers sharing ideas and activities. This particular blog post offers ideas, resources and activities for teaching forces of motion to children in primary grades. Amy Hinz has used Pinterest to create a board with 144 activities that can be duplicated at home and in the classroom. Steve Spangler also offers an extensive collection of activities for a variety of grade levels. Motion and Forces is the site that impressed me the most. The ability to digitally construct experiments gives students an opportunity to use technology to engage in problem solving. The site also offers correlations to NSES standards.
