- A Visual Overview: Show the slideshow of photos to your class. Each has a descriptive caption and kid-friendly copy for your students to read. (Please note that there is also more extensive teacher note copy just for you.)

Click the thumbnail slides below to see the captions and kid-friendly copy up close.
