This video documents how scientists, using marine algae, can study climate change in the past to help understand potential effects of climate change in the future.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

This video montage of spectacular NASA satellite images set to music shows different types of ice and ice features as well as descriptions of satellite-based measurements of ice cover. Text captioning describes how global ice cover is changing, and how this is measured.

This fuel cell animation demonstrates how a fuel cell uses hydrogen to produce electricity, with only water and heat as byproducts. The animation consists of four parts - an introduction, fuel cell components, chemical process, and fuel cell stack.

In this activity, students consider the impact and sustainability of use of different classes of biofuels on the economy, the environment, and society. Students also learn about bioelectricity and how converting biomass to electricity may be the more efficient way to fuel cars in the 21st century.

This video shows the people of Bhutan working to prevent flooding from an outburst of a glacial lake in the country's Lunana region.

This site provides a useful set of graphical representations of mean temperature change in different land/ocean surfaces over the past 120+ years.

Students observe cloud type and coverage, as well as other weather conditions over a five-day period and correlate these observations. Students make and test predictions using these observations.

Students will work with short-term and long-term air temperature data in order to better understand the differences between weather and climate.

Students observe, sketch, and describe clouds on their own before learning to identify cloud types by comparing photos of different clouds to their sketches.

In this interactive simulation, students can explore global CO2 emissions displayed by different continents/countries and plotted based on the GDP. A map view is also accessible.

The lesson plan describes activities focusing on the big question, does eating locally grown food help reduce your carbon footprint? Many elements are interconnected and function together to create the natural and productive living system that is your garden. At the end of the activity guide there are additional lesson plans, activity guides, and videos that can help you bring together soil, water, habitat, food, and community to explore your dynamic garden ecosystems.

Many elements are interconnected and function together to create the natural and productive living system that is your garden. The purpose of this activity guide is to teach students the ecological functions found in any natural system and model how these functions are performed by a natural area like a garden.

NASA produced white-board animation video explains key concepts about the role and source of carbon dioxide as a greenhouse gas.

This is an activity that uses basic algebra to assess the costs and savings of electric vehicles. It uses math to measure the trade-offs of buying electric versus gas-powered car models.

A board game which engages students as they grapple with the complexities of society's challenges. It encourages students to cultivate a deep and layered understanding of these challenges and current societal options for producing energy.

In this activity, students learn about the energy sources used by their local utility provider to generate electricity, and work in small groups to evaluate the sustainability of either a renewable or non-renewable energy source used to generate electricity.

This video describes how geothermal heat resources in California have been tapped to supply 850 MW of electricity. Images and animations show how the area known as The Geysers has been developed to capture steam, produced from trapped rainwater and heated by the earth. Major challenges include finding suitable geothermal resources to develop, and ensuring that underground water is replenished.

This lab, created by Salish Kootenai College faculty, steps undergraduate students through ordering, accessing, and graphing local precipitation and temperature data.

This is a simulation to explore how climate change will affect a specific region in the coming decades. Graphs and maps in The Climate Explorer help students understand past, present, and future climate projections for their location.
