Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

Assist your class with learning the importance of caring for our environment as they complete this fun-filled lesson on climate change. Individuals perform simulations related to greenhouse gases, atmospheric gases, and the overall...

Examine the environmental hazards associated with volcanoes with a three-part science lesson. In the pre-lab, first graders learn that gas, landslides, ash, and lava are all hazards that come from volcanoes. They then explore...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Instructional module focusing on Earth's atmosphere. Discussion includes major components, layers, air pressure, and scientific monitoring of the atmosphere. Site also includes an interactive practice quiz and links relating to the topic.

This is the sixth lesson in a series of learning modules on the topic of climate change. It takes a look at the different important greenhouse gases in our atmosphere and some of the ways in which humanity is affecting the atmospheric...

An explanation of how temperature is affected by the composition of the atmosphere and how energy flows in and out of Earth's atmosphere.

There is evidence that the Earth's early atmosphere contained less oxygen but more carbon dioxide and water vapor than it does today. Increased emissions of greenhouse gases have led to climate change. Link to a test is included.

Through this interactive module, students learn that the atmosphere is so much more than air, its complex role on Earth should be explored, and its quality carefully monitored and protected.

This is the third lesson in a series of learning modules on the topic of climate change. It takes a look at how greenhouse gases cause warming and affect Earth's climate. Includes comprehension questions and interactive tools for...

An inquiry-based science unit for middle school students centered on weather and climate. The lessons integrate technology and lab activities while teaching about Earth system energy balance, greenhouse gases, paleoclimatology, and how...

This is the second lesson in a series of learning modules on the topic of climate change. It examines what climate change is, how it relates to greenhouse gas concentrations over time, and temperature trends. Includes comprehension...

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of...

This site introduces global warming, and the greenhouse effect and the gases contributing to it.

The atmosphere has not always been the same. It has been much the same, but nevertheless now contains more nitrogen and oxygen, and less carbon dioxide, than it did when the earth first formed. Recently, the addition of greenhouse gases...

There's a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide- a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels that...

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."
