In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages. This activity also introduces learners to greenhouse gases, infrared radiation, and global warming.
Students will differentiate between the good and bad ozone, locate the position in the atmosphere where the good and bad ozone reside, plot monthly ozone data, and understand the ground level ozone effects on humans and plants.
This lesson is the first of a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. In this activity students examine different scientific aspects of hurricanes, all in an effort to begin to understand the nature of motion?particularly how changes in speed or direction of motion are caused by forces.
This lesson is the second in a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. In this activity students? study of hurricanes is broadened by exploring how technology and science are used today to identify, measure, and track powerful tropical storms to better warn and secure people from their often-devastating impact.
Guided reading to introduce students to the study of the atmosphere
In this lesson, students learn about air. Through a variety of hands-on experiences presented as stations in the classroom, students will discover properties of air, including that air has volume, mass, and pressure; that it is compressible; and that it expands when heated. They will also learn about the major molecular components of our atmosphere (nitrogen, oxygen, argon), the four layers of our atmosphere, and that air contains water vapor. Note: The videos referenced in the lesson narrative are no longer available online, but the station activities are not dependent on the content in the video.
Students learn the composition and layers of the atmosphere through discussion, creation of a scale model, and a written exercise.
Compare composition, properties and structure of Earth's atmophere.
In 1899 and 1900, Secretary of State John Hay issued what became known as the Open Door Notes to foreign powers involved in China. Secretary Hay called on those powers to respect the rights of each other, to agree to an open market and equal trading opportunities for merchants of all nationalities, and to respect the territorial and administrative integrity of China.
In this activity, students research the names and characteristics of each layer of the Earth's atmosphere, and then create a representation of the atmosphere.
This tutorial describes the atmosphere: the layers, its composition, and its properties.
Students will experiment to understand variations in the amount of ground-level ozone between different places in their neighborhood, town, or city.
This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) Mars needs to maintain surface water. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.
In this activity, students create a device to demonstrate and investigate one atmosphere of pressure at sea level.
This quiz assesses student knowledge of clouds and aerosols.
In this activity, students use chocolate candies to create pie graphs that show their understanding of the composition of air. They discuss why knowing this information is important to engineers and how engineers use this information to improve technology to better care for our planet.

This curricular unit is meant to engage students in scientific inquiry and hands-on measurement of the atmosphere. The lessons enable students to apply math and science to explore the challenge of air pollution in their own community.
