The lesson on adaptation and evolution included here is a bit difficult to navigate using the teacher notes, but if you start with the handout, there are directions to guide you through the lesson. The link to the scrapbook within the document is broken, but is included here under additional materials. Once in the scrapbook, click on an animal, then click the video button below the slide show pictures to access the videos referred to in the handout. Depending on how many of the videos the kids watch, the duration of the activity could vary greatly.
