EXPLORE temporal resolution and participate in a temporal resolution activity.

Ask students how remote sensing could be used to recognize changes on the earth.

Prompt students to participate in the activity: The only thing constant is change During this activity students will have the opportunity to "sense" changes over time. Activities 1 and activity 3 are highly recommended for helping students understand temporal resolution. 

Optional Activity: Have students sense the changes in their school's neighborhood by taking pictures from the same spot at different times, either during a single day or over a series of days. Compare the different sets of photos and have students talk about how their neighborhood has changed over time. For detailed information see the 2nd activity of Sensing change in your neighborhood.

Teacher Note: Teachers who use the optional activity should be prepared to view this activity as long-term. It may take time to take and develop photos. Thus, it is recommended that students begin to take photos a week or so before this lesson. Then, they can analyze the pictures and develop a concept of temporal resolution during this lesson.    

Prompt students to write a definition of temporal resolution. See Activity sheet: Defining the terms (PRSM-1).

 

Debrief the students by asking how many times they think they will need to fly over Kailua Bay to locate and evaluate the changes of the coral reefs over time? Ask them to justify their answer.
