INFORM students of the relationship between the sensory
map activity and remote sensing fundamentals. Students will begin to develop
an understanding of remote sensing by relating the sensing map activity
to remote sensing fundamentals – process and elements.
Prompt students to relate the sensing activity they just completed
to the process of remote sensing.
- What did you see in the area?
- Based on your sensing activity, what did the area look like?
- How were you able to draw a map of the differences in temperature?
- What process did you have to go through to develop this sensory map?
Prompt students to think about the necessity of airborne remote
sensing.
Ask:
- If the hot and cold regions were really big, how can you sense those
areas?
- If your sensing areas are inaccessible
such as coral reefs under the sea or are in dangerous locations like
an erupting volcano, how can you sense those areas?
- What types of instruments are needed to sense places like these?
Inform students that the activity they just completed is representative
of how remote sensing instruments work. Now that they have seen an example
of remote sensing, they will further explore each of the elements of remote
sensing and how they work together to provide scientists with the data they
need to study the earth. Your goal is to develop a detailed drawing and
description of how remote sensing works. |

Sample student responses:
- A 2 ft. by 2 ft. area with high and low points, the location of the
high and low points.
- Different parts of the area were either hot, warm, cool, or cold,
and the location of temperature boundaries.
- Moving my hand over the area, I could feel (prompt for "sense")
changes in temperature and I gave that information to my teammate who
indicated the changes on the map.
- First we drew a picture of what we saw, then we gathered temperature
information by waving our hands over the area (not touching it), and
transferred that information onto our map.
Sample student responses:
- Sense large areas from the air or space.
- Airborne and space-borne remote sensing instruments could be used
to sense large, inaccessible, or dangerous areas.
