A discussion of the interactions between the four spheres of Earth and how they affect weather and climate. The slideshow is divided into two parts. The first deals with interactions between the atmosphere and the hydrosphere and the...

Use this interactive infographic to learn about the function of greenhouse gases, and how they affect heat in the atmosphere.

In this activity, students plot data on the concentrations of various greenhouse gases in Earth's atmosphere and look for trends. They will learn that greenhouse gases allow the Sun's light to pass through them to the surface of Earth,...

In this activity, students will observe the effect of the gases resulting from a burned fossil fuel on the heat absorption of air and determine the ability of phytoplankton to remove greenhouse gases from the atmosphere. This activity is...

One lesson in a larger module covering different aspects of the major greenhouse gases including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases.

Using this map from NASA you can calculate the concentrations of carbon dioxide in the atmosphere. Solve the four problems and you will see how concentrations are spread across the globe and where there are regional differences.

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 2 of 3 in the series titled "The Biosphere."

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 3 of 3 in the series titled "The Biosphere."

This lesson will discuss the importance of the biosphere (the global ecosystem) to living things. It is 1 of 3 in the series titled "The Biosphere."

Breathing Earth layers data about rates of carbon dioxide emission along with birth and death rates onto a map of the world in a real-time simulation of one of the principal greenhouse gases in the Earth's atmosphere, CO2.

In this lesson young scholars investigate how much greenhouse gas (carbon dioxide and methane) their family releases into the atmosphere each year and relate it to climate change. To address this, students use the Environmental...

Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By...

Provides a great introduction to Boyle's Law as well as a link to a more detailed explanation if that's what you're looking for. Gives a real life example that is very helpful in comprehending the law.
