I use this lesson when integrating Science into my picture books that have an elephant as the subject of the book. Examples include: Elmer, Horton Hatches the Egg, Horton Hears a Who!, etc. As students fill in the chart with their prior knowledge staff then click on the elephant image to reveal factual information (in regards to the topic). There is also a video linked in for each category. ***Some of the videos are longer (no video is longer than 3 minutes)and I do not show the whole video. In some videos 30 seconds is enough.
