We have annotated several hundred teaching resources cataloged in the National Science Digital Library with spatial concept terms listed below. We have also created a new TeachSpatial collection annotated in the same way. The concept terms were drawn from the U.S.National Science Education Standards (NSES 1996) for topic areas B - Physical Science, C - Life Science, D - Earth and Space Science, as well as from the 1994 U.S. Geography Teaching Standards for grades 9-12. Those standards can be browsed here.

This lesson is the first of a two-part series on laughter and how it can affect the immune system. In this lesson, students explore gelotology (the science of laughter) and its benefits to our social, mental, and physical well-being. The first lesson has a twofold focus. First, it focuses on the science of laughter in terms of how the brain reacts to an external stimulus that is funny. Second, it explores the positive effects of laughter in terms of our social, mental, and physical well-being.
