 Air, Water, Land, & Life: A Global Perspective

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.

Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.

Explore and connect to the GLOBE Water Quality protocol bundle. 

Working in teams, students learn how a STEM professional uses STEM practices to solve real-world problems, design a STEM Career Connection Badge that highlights their takeaways about that profession, and build a training station to teach their classmates during a STEM Career Conne
