In this unit, students investigate temperature cycles, tree rings, CO2 records, and the effects of CO2 on temperature, precipitation and cloud cover to determine the impacts of changing climate on forests. After gathering and analyzing local data,... (View More) students examine regional impacts and differences. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard." (View Less)

Students are introduced to the carbon cycle through discussion, modeling and a game. Students then complete activities and investigations on Greenhouse gasses, photosynthesis, cellular respiration and ecosystem services (functions and values of...

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.
