Activities are brief but have simple support tools.
How I Use It
I would use it to introduce a topic, allow students to engage in the videos, and direct them to the activities that will allow them to do simple, yet informative asks to understand the concepts. It could be used with laptops or tablets that can access Flash and YouTube. I wouldn't use it for advanced learners unless you are introducing the concept. For special education students and ELL students the videos are a good way to access the information in a very simple, direct way.
It was easy to navigate and had some nice topics. Some of the topics had simple activities that would need to be paired with further investigations. The activities also had videos that had to be accessed through YouTube. The Educator Page is still a work in progress but the bottom of the page had related links to connect to other topics. This would be decent to use as an introduction to a topic and a place to go to find information. It would be a tool that I could use to supplement a unit in Science.
