In this video clip, learn about precipitation and how clouds are formed. Find out why scientists study clouds and how students can help NASA collect cloud observation data. NASA eClips™ are short, relevant educational video segments. These videos... (View More) inspire and engage students, helping them see real world connections. The Real World series of NASA eClips™ connects classroom mathematics to 21st century careers and innovations and are designed for students to develop an appreciation for mathematics through real-world problem-solving.

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)

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... (View More) intact ecosystems to humans). 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)

In this science-based storybook, students Anita, Simon, and Dennis want to know why the sky isn't always blue. They learn that there's a lot more than air in the atmosphere, which can affect the colors we see in the sky. Four activities accompany... (View More) the book. The book is one of a series in the Elementary GLOBE unit designed to introduce students to the study of Earth system science (ESS). Each book has companion learning activities that complement the science covered in each story. Together, the books form an instructional unit that addresses ESS and related subjects (e.g., weather, water, seasons, soil, and aerosols). The GLOBE Program is a worldwide, hands-on, K-12 school-based science education program. (View Less)

Designed for Science On a Sphere, this video is narrated by NASA scientist Peter Griffith who explains fast and slow carbon cycling on Earth. A banana is an example of fast, young carbon. A chunk of coal is an example of old, slow carbon. Carbon... (View More) dioxide and vegetation on land seen from space by satellites show the annual cycle: as plants grow during spring and summer they draw carbon dioxide out of the air during photosynthesis. When they die or go dormant during winter, carbon dioxide levels rise in the atmosphere. Burning fast or slow carbon to generate power or heat releases black carbon, also called soot which can be seen from space. (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.
