This well-designed experiment compares CO2 impacts on salt water and fresh water. In a short demonstration, students examine how distilled water (i.e., pure water without any dissolved ions or compounds) and seawater are affected differently by increasing carbon dioxide in the air.

In this interactive, students explore, at their own pace, how global climate change may affect health issues. Issues include airborne diseases, developmental disorders, mental health disorders, vector-borne diseases and waterborne diseases.

An interactive simulation of Earth's seasonal dynamics that includes the axial tilt and other aspects of Earth's annual cycle.

This is part of a larger lab from the University of Nebraska at Lincoln:

This is a hands-on inquiry activity using zip-lock plastic bags that allows students to observe the process of fermentation and the challenge of producing ethanol from cellulosic sources. Students are asked to predict outcomes and check their observations with their predictions. Teachers can easily adapt to materials and specific classroom issues.

In this short but effective demonstration/experiment, students investigate how thermal expansion of water might affect sea level.

This simulation allows students to explore the change in sea surface pH levels with increasing CO2 levels.

This animation depicts real-time wind speed and direction at selected heights above Earth's surface, ocean surface currents, and ocean surface temperatures and anomalies.

Here students use data from the NOAA carbon dioxide monitoring sites, such as Mauna Loa, to graph the Keeling Curve for themselves on large sheets of paper. Each group graphs one year, and the graphs are joined at the end to reveal the overall upward trend. The explanation describes the carbon cycle and how human activities are leading to the overall trend of rising carbon dioxide.

Our Coast, Our Future (OCOF) is a collaborative, user-driven project focused on providing coastal California resource managers and land use planners locally relevant, online maps and tools to help understand, visualize, and anticipate vulnerabilities to sea level rise and storms.

One of a suite of online climate interactive simulations, this Greenhouse Gas Simulator uses the bathtub model to demonstrate how atmospheric concentrations of CO2 will continue to rise unless they are lowered to match the amount of CO2 that can be removed through natural processes.
