Nice digital addition to several math and science lessons.

I watched the water cycle and photosynthesis videos and was very impressed at how intricate systems like these were broken down into easily understood ideas. Both started off with a question as to what the system was, reinforcing the idea of inquiry/curiosity paving the way to learning something. I've never heard photosynthesis equated to following a recipe, and all the cooking metaphors worked so smoothly with the processes explained. The graphics were colorful, editing features like zooming in to show detail were effective, and having important vocabulary in capitalized white letters was great visual reinforcement for the information conveyed auditorily. I agree with others that the subjects should expand beyond science and math because the content already here is incredible!

This is a good kick off lesson, wrap up lesson, or review activity. Students can work independently or you can use it as a whole group or small group lesson. Students have always been very engaged as they do the activities and therefore is a great motivation to help them to learn!

I think it is a useful, user-friendly, FREE website that helps supplemental topics in math and science. It can help our digital natives gain more understanding on a topic and even practice independently or with a group. For the performers, several topics offer karaoke as a supplemental component. I wish the site would add Language Arts and Social Studies topics as well.
