Question How does your distance from an object affect what you
see?
Objective
Students will learn about perspective and how distance affects
their field of viewand ultimately the type and amount of information
they obtain.
Approach
[To
be written when programming is completed.]
Reflection
Discuss the uses of remote sensing and the benefits of looking
at things from a different perspective. One common use of remote
sensing is for the prediction of weather. The line of questioning
may go as follows: When weather forecasters predict the weather,
where do they get their information? Do they just look outside to
see what the weather is like in their neighborhood? What tools do
they use? Students should describe the RADAR images that weather
forecasters use. Often these images are superimposed over maps to
show the movement of clouds, hurricanes, etc. across the country.
Weather forecasters also look at the entire nation to examine weather
patterns that may be approaching their area in the near future.
After
the discussion, students may construct shoebox ecosystems and satellite
models. They can define missions for their satellites and suspended
the satellites above their ecosystems to "collect data." Satellite
missions may include monitoring threatened species, vegetative ground
cover, or weather conditions. Ask students to explain the difference
between the type and amount of data they can collect from their
satellite and the type and amount of data they can collect on the
ground in the ecosystem.
