In this activity, students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five years and annual variation driven by photosynthesis. This exercise enables students to practice basic quantitative skills and understand how important sampling intervals can be when studying changes over time. A goal is to see how small sample size may give incomplete picture of data.

In this video segment adapted from NOVA, find out how cars made of a material stronger than steel and half the weight can help combat climate change.

This video features a number of different climate scientists describing the effects of the increasing amount of carbon dioxide on global climate and proposing a series of solutions to mitigate these effects. Video addresses health problems and other costs to humans associated with climate change.

In this video segment from NatureScene, explore Cartwheel Bay, a wetland in South Carolina, and learn about the variety of carnivorous plants native to this unique landform.

In this video adapted from Texas Parks and Wildlife Department, learn about carnivorous plants that act as both producers and consumers in an ecosystem. See sundews and blatterworts capture and digest insects.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.

This interactive resource adapted from the National Park Service presents the key concepts of cave and karst systems, including how and where they form, different types, and various cave environments.

This activity engages learners in exploring the impact of climate change on arctic sea ice in the Bering Sea. They graph and analyze sea ice extent data, conduct a lab on thermal expansion of water, and then observe how a scientist collects long-term data on a bird population.

Students run a simplified computer model to explore how climate conditions can affect caribou, the most abundant grazing animal in the Arctic.

This animation illustrates how the hardiness zones for plants have changed between 1990 and 2006 based data from 5,000 National Climatic Data Center cooperative stations across the continental United States.

In this activity, students research changes to the environment in the Arctic/Bering Sea over time using oral and photographic histories. Developed for Alaska Native students, this activity can be customized for other regions.

In this video adapted from the Arctic Athabaskan Council, learn how warmer temperatures in the Arctic are transforming the landscape, triggering a host of effects such as permafrost thawing and insect infestations.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This activity engages students in the analysis of climate data to first find areas in the southern United States that are now close to having conditions in which the malaria parasite and its mosquito hosts thrive and then attempt to forecast when areas might become climatically suitable.

This video addresses the impact of climate change on several butterfly populations. Warming temperatures lead to shifts in location of populations of butterflies or die-offs of populations unable to adapt to changing conditions or shift to new locations.

This video provides a comprehensive introduction to the role of coral reefs, the physiology of corals, and the impacts of ocean warming and acidification on coral survival. It highlights experts from the Bermuda Institute of Ocean Sciences and the University of Miami.

This video illustrates conditions under which two infectious diseases - cholera and dengue fever - flourish, and how climate change is likely to exacerbate those conditions. Note: you may need to scroll down the Changing Planet video page to get to this video.

This NBC Learn video features climate scientists doing their research on Mt. Kilimanjaro to study the climate of the past. The scientists put the recently observed changes on the glacier into perspective by comparing past climate fluctuations, stressing that the current observed rate of change is unprecedented. Note: you will need to scroll down the Changing Planet video page to get to this video.

This video addresses acidification of the ocean and the ecological and economic implications of the resulting pH change on marine life. It includes information about how ocean acidification resulting from increased absorption of CO2 from the atmosphere is affecting ocean species such as sea urchins and oysters. Scientists from the University of California at Santa Barbara discuss their experiments with sea creatures in acidic sea water. There is an associated lesson plan and classroom activity that has students test the effects of CO2 on water pH.

This video follows Bermuda scientists into the field as they collect data that documents a warming trend in ocean temperatures. BIOS Director Tony Knapp discusses some of the impact of warming temperatures on sea levels, storms, and marine ecosystems.
