This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum. Inexpensive, off-the-shelf components are used to... (View More) build a light sensor and source, creating a simple spectrophotometer that can measure light absorption. In the second part of this activity, principles of ocean color remote sensing are applied to measure reflectance. Using components that are clearly visible allows students to configure them in different ways. Playing with the instrument design gives students a practical understanding of spectrophotometers, in-water optics, and remote sensing. As an extension of this concept, students are encouraged to think about how ocean color is used to estimate the concentration of chlorophyll to infer phytoplankton abundance, colored dissolved organic matter, and suspended sediments.

This Science On a Sphere video and docent show (script and playlist), explores factors that render Earth habitable and influence Earth's energy budget. The video gives an overview of NASA's Search for "Goldilocks Planets" - planets that are not too... (View More) hot or too cold for liquid water. (View Less)

This series of ten lessons has been developed to teach students about local and global water issues. They are based on NASA’s Global Precipitation Measurement (GPM) Mission. The activities are done largely outdoors and include scientific data... (View More) collection and analysis and integrate technology. Many of the lessons involve data collected based on protocols from the GLOBE Program. Each lesson is designed to take one hour; the lessons build on each other, but can also be used independently. Each lesson topic includes a lesson plan, PowerPoint presentation, student capture sheet and capture sheet answer guide. (View Less)

In this activity, participants learn about the atmosphere by making observations and taking measurements. They will go outside and use scientific equipment to collect atmospheric moisture data (temperature, relative humidity, precipitation and cloud... (View More) cover). Students will use this qualitative and quantitative data to understand how water is found in the atmosphere, how the atmosphere determines weather and climate, and how Earth’s spheres are connected through the water cycle. The data collection is based on protocols from the GLOBE program. This activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons. (View Less)
