Lesson Snapshot

1. Engage: Students will view random thermal images and brainstorm ideas for practical uses of thermal imaging. Students will then discuss what is actually being measured and how thermal imaging might work.

2. Explore: Students will collect ambient air temperature data from predetermined locations around their school site.

3. Explain: Students will report their data into a class data table and analyze it for inconsistencies.  Students will discuss the cause of the wide variations in the data and find that the lack of experimental control is the most likely cause.

4. Extend/Expand: Students will identify the variables in the experiment and specifically identify control variables and create procedures for collecting the data.  After the class has agreed upon the controls, they will recollect the temperature data, return to class to determine if their controls affected the reliability of the data.

5. Evaluate: Students will convert their temperature data into a thermal map showing the hot and cold spots in the school.  Students will include this map in a written report outlining where the school is possibly losing heat energy and what steps the school could take to lower this loss and reduce energy costs.  These reports may be reviewed and some selected to be shared with the school administrator or energy manager.
