This is the United States Geological Survey website. It contains resources for primary, secondary, and undergraduate education. The resources are lessons, data, and maps.
This resource shows how the rock cycle works. It plays an interactive video step by step. You can click on each step for further information about each step.
This website has a lot of fun easy science experiments. I found this website because my cooperating teacher uses it in her study hall classroom. The experiments relate to many different types of science. Most of them require minimal materials!
This resource is also used in the classroom I am in. It has an everyday news video about what is going on in the world that would interest middle school aged students. I am also quite interested in the videos when they are shown in class.
