Lesson Title: Earth Versus Mars
Remote satellite images of Earth and Mars are used to compare and contrast physical processes that occur on both planets.
• Identify similarities and differences between the physical processes that occur on Earth and Mars.
• Classify images of Earth and Mars by observing physical features in each image.
• Speculate about the physical features observed in each image.
Lesson Activities and Sequence
Earth vs. Mars: What similar physical processes occur on both Earth and Mars?
In this activity, students work in pairs to compare and contrast the physical processes that may be inferred through the observation of images of both Mars and Earth. They will discuss the processes that have occurred on the Earth and the outcomes that have resulted, and transfer this knowledge to the interpretation of the processes that may have occurred on Mars.
Keywords: physical processes, geography, planet origins, erosion, landforms, earthquakes, volcanoes, atmosphere, fluvial, canyons, channels, craters, uplilfting, downcutting
- Earth vs. Mars: Charting the physical characteristics of both Earth and Mars
In this activity, students work together to fill in the missing information on the comparison chart (link above, page 15). They will then use other resources to create a representation (Venn diagram, graph, powerpoint, etc.) to share with the class. This representation will show how Earth and Mars are alike and different.
Keywords: distances, diameter, volume, orbital tile, surface temperature, day, year, charting, journal, compare and contrast
