My Take
This website has a plethora of information for students (and teachers) to learn key concepts. It is a little dry in its delivery but it does a good job explaining key ideas and concepts. If the kids are genuinely interested in the topic, this will do a good job at taking them further. They are able to watch and re-watch any ideas or concepts they are struggling to understand using this website.
How I Use It
I have used this website in the science classroom during a rotation style or stations based learning centers where student will discover key ideas as they relate to science ideas. It would be beneficial to include discussion points for student groups to analyze after watching the video. This will hold them accountable for the information presented. Another use for this website is to give students who missed a particular day in the classroom a way to obtain the material. I have seen teachers use this for a flipped classroom setting.
