Acting as the ICESat-2 satellite, students investigate the reflection of light photons off Earth's surface by catching and recording a number of photons. Using bouncy balls to represent the photons, students drop, let bounce once and try to catch in... (View More) one hand as many balls (photons) as possible. Drops occur on carpeted and non-carpeted areas, and with and without the presence of cardboard buildings, to represent different Earth surfaces. The lesson includes background information, instructions and concluding questions. Related Next Generation Science Standards (NGSS) are listed. (View Less)

This unit consists of four activities. Students begin by examining temperature cycles (current, recent and historical) then add in factors such as carbon dioxide, precipitation and cloud cover to discover regional and global differences in the... (View More) effects of climate change. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard." (View Less)

This unit consists of two parts, each with several activities which require students to participate in investigations, discussions, computer data analysis, role-playing, and research. In Part 1, students examine the roles of Earth's energy balance... (View More) and the greenhouse effect in creating and affecting climate. Part 2 focuses on the biosphere as a system. Students examine the interactions of organisms, the effects of climate change on food webs, and the importance to humans of a healthy, intact ecosystem. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard." (View Less)

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 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)

The total amount of water on Earth, the places in which it is found and the percentages of fresh vs. salt are examined in this lesson. A short demonstration allows students to visualize the percentage differences and a coloring exercise illustrates... (View More) locations. This lesson uses the 5E instructional model. All background information, student worksheets and images/photographs/data are included in these downloadable sections: Teacher's Guide, Student Capture Sheet and PowerPoint Presentation.

Intended for use prior to viewing the Science on a Sphere film "Water Falls," this lesson introduces students to Earth's water cycle and the importance of freshwater resources.
