This can be a fun activity for the little ones, especially if you get creative and start using different colored chalk and use them to trace and decorate your shadows instead of just taking pictures of them. Although the site has very clear and easy-to-follow steps, it does not provide any background information or additional resources to help a parent or adult educate their young ones about the science concepts observed. More background information, discussion questions, or even extension points would greatly increase the quality of the lesson.
