Activity Prep

In this Mystery, students think about their experiences with hot and cold weather, and learn about a real city where the sun never shines in winter. In the activity, Chill City, students experiment with different types of materials (opaque, transparent, and reflective) to figure out how to reflect light. They use this to bring light and warmth to an imaginary paper town.

Prep Instructions

We suggest students work in pairs. Homeschool students can work on their own.

Find A Source of Light

In this activity, students fold their worksheet so that part of the paper acts as the mountains, casting a shadow over “Chill City,” the paper town on the worksheet. For this to work, you need a light source that is NOT overhead. We have used desk lamps, table lamps, or light from a window.

Chill City

If your window isn’t bright enough, a table lamp with no shade can work well as a source of “sunlight.” Put the lamp on the floor and have students sit in a circle around it. To test your light source to make sure it will work, or this activity, we recommend that you print out a copy of the Chill City worksheet and try steps 3 to 6 of the activity instructions.

Prepare Materials

Cut each report cover into two sheets at the fold. Then cut each sheet into 8 equal pieces, like this: Chill City

Do the same for the black construction paper, colored construction paper, and aluminum foil.

Assemble Envelopes

For each pair of students, assemble an envelope of supplies containing:

  • 3" x 5" card
  • 3” x 5” piece of aluminum foil
  • piece of clear plastic
  • piece of black construction paper
  • piece of colored construction paper
