In Week 4, we discover why cities warm up by exploring different materials with a FLIR thermal camera and thermal color-changing stickers.
Join Earth Doctors
Create a model of urban materials and see how hot or cool they get.

Imagine what a thermal camera might see on this detailed urban heat island coloring sheet.

Find which parts of the home might be losing heat using color-changing thermal stickers.

Hire a commercial thermal drone operator to map your school in summer and see how much heat different materials are holding.
-1.avif)
Put your thermal materials on a board.
-2.avif)
Warm the board for 10 minutes with the heat lamp (or leave it in direct sun if it’s a hot day).
.avif)
View the board with a FLIR thermal camera, write the temperatures of the materials on the worksheet, and rank them in order.



Learn which nanometer wavelengths correspond to different colors.
