DIRECTIONS:
This activity can be done either of two ways: by having students work with printouts from materials on the Web, or by directly accessing Web pages on the Internet.
Directions for completing the activity by having students access Web pages on the Internet
Getting Started:
- Go to the Windows to the Universe website at www.windows2universe.org
- Select Our Planet.
- Select Atmosphere. Be sure to select "Advanced" from the reading level options. (Blue button bar near top center of page)
- Click on the link to the layers of Earth's atmosphere.
- Complete the student worksheet as directed in the following procedures.
Completing the Assignment:
- To complete Data Table 1, click and read each of the following sections. After reading each section, use your web browser's “Back” button to return to the "Layers of the Earth's Atmosphere" page.
- Troposphere
- Click on the image to view the enlarged version of the "Average Temperature Profile of Earth's Atmosphere" graph.
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere
- To complete Data Table 2, view the image The Average Temperature Profile of the Earth's Atmosphere. Be careful when reading the graph - you are asked for the maximum temperature in each layer, which will be a position farthest right. Also, you need to remember to read the image from the bottom up as the image starts with an altitude (y-axis) of 0 (ground level) and continues up. To complete the 'Ionosphere' part of Data Table 2, you will need to read Different Regions of the Ionosphere. Find the altitudes between which the ionosphere exists, calculate the thickness then go to The Average Temperature Profile of the Earth's Atmosphere to determine the maximum temperature of the ionosphere.
- To complete Data Table 3, continue to refer to The Average Temperature Profile of the Earth's Atmosphere. Pay close attention to what is happening to the temperature as you travel from the bottom of a layer to the top of the same layer.
