An interactive graph that predicts how many years until more than two dozen natural resources (e.g., chromium, oil, tin, coal, etc.) are depleted, based on current production rates or production that grows each year. Use the slider at...

Using a web quest, simulations, and hands on activity, learners will gain a basic understanding of semiconductors, diodes, and photovoltaic cells. In these activities students will learn how electrons migrate in semiconductors and...

A lesson outline for The Fishing Game, which is located on a linked website. Teachers register a class from within the game. Students compete against two fishing companies and try to make the most profit they can over a ten-year period....

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful...

You may have heard of CFCs and how harmful they can be to the ozone layer, but do you know the process that chlorine undergoes to contribute to this destruction? NASA explores this topic and has charted the depletion of the ozone since...

This site provides information and activities for classes to learn more about ozone depletion and UV radiation.

Is the world running out of gas? Teach your students how their lives impact the depletion of non-renewable resources, specifically oil, and how the depletion of those resources will effect the future.

This article explains what the ozone layer is, why it is important, and how we can help to slow down its depletion from the atmosphere.

Several visualizations that help students understand the basic properties of semiconductors. Students can turn a silicon crystal into an insulator or a conductor, investigate the probability waves of an electron, and make a depletion...

Explains what carbon dioxide is, where it is found, sources of it, and describes human activities that contribute to carbon depletion and increased levels of carbon dioxide in the atmosphere. (Updated: February 22, 2013)

Site creatively explains the causes and effects of ozone depletion. Then asks the question. Is there a hole? Grades 3-6.

Humans are having a negative effect on the ecology of Antarctica. Get the facts on krill harvesting, global warming, and ozone depletion.

Easy to read and understand site from Environmental Education for Kids. Good and bad ozone explained and illustrated. Complete with glossary and Quizzler at the end.

This PDF resource describes the scarcity of water, the locations and amount of water of groundwater around the world, methods for reducing this scarcity, and the causes of the depletion. Provides a prediction for areas of groundwater...

[Free Registration/Login may be required to access all resource tools.] This study guide summarizes key points about efforts to fight ozone depletion in the atmosphere. Includes a few questions to check for understanding.

Article explains efforts in England to help Natterjack toad populations grow through introducing populations from different parts of the country into depleted areas.

A quantitative illustration of how non-renewable resources are depleted while renewable resources continue to provide energy. The activity requires students to remove beads (units of energy) from a bag (representing a country). A certain...

Use this board game to introduce the concepts of energy use in our lives and the very real impact that personal choices can have on our energy consumption, energy bills and fuel supply. The game begins as students select cards that...

Students will use this activity to determine what keeps our bones strong. Soaking the bones in vinegar will remove the calcium from the bones causing them to become soft and rubbery. Students will find that when we age, calcium is...

Several activities are included to teach and research the differences between renewable and non-renewable resources and various energy resources. Students work with a quantitative, but simple model of energy resources to show how rapidly...

Will our descendants enjoy lives that are richer, more fulfilled, healthier, and in general better than those of today? Or will human societies collapse under the strain of depleted resources, brutal conflicts, and environmental damage?...

A detailed analysis of how nonrenewable resources will not disappear but will become increasingly scarce in the years to come. Supported by research data, graphs, and tables on the scope of nonrenewable resources, and how much we have of...

Article describing the scope of the problem of overfishing in the ocean and in fresh water bodies around the world. Adverse effects of this practice on both natural and human systems, and efforts to contain it are detailed. (Published:...

This video segment adapted from NOVA/FRONTLINE looks at American energy consumption and the resulting production of greenhouse gases. [4:59]
