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.

Students categorize causes, effects, and responses to volcanic hazards through an Earth system perspective. They use remotely sensed images to examine the visible effects of the eruption of Mount St. Helens in 1980 and identify a buffer zone for safer locations for development.
Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.
Students collect and analyze temperature data to explore what governs how much energy is reflected.
This activity is designed to introduce students to geologic processes on Earth and how to identify geologic features in images. It will also introduce students to how scientists use Earth to gain a better understanding of other planetary bodies in the solar system.
Students discuss their current understanding of what Earth systems are and how they work and consider how to identify the boundaries of a region for Earth system study.
