How I Use It
I use it at the start of the topic and at the end of the topic. Sometimes I will use this website for quizzes. I will have the students watch the video on the subject and give the a worksheet quiz on the video to see how well they were paying attention to the video. I recommend this site for second grade and up.
I found that this a great tool to introduce a brand new topic in science but also great for reviewing a topic. The website provides additional games and activities on the topic which my students love.
