This site is for teacher education. It features streaming video presentations on research lab techniques, inquiry science, and assessment. The Slide Library is a great resource where teachers will find hundreds of searchable slides that can be downloaded and used to customize their own lesson plans and activities. Each slide includes talking points and references. The Teacher Resources area includes ready-to-go lessons and instructional materials such as the grade 4-8 activity guides: sleep and daily rhythms, muscles and bones, and food and fitness. There is also a separate section for K-5 educators that includes presentations, slide sets, teacher resources, and professional development.
