A Clear Sleeve for the Ridge Thermometer

Test materials to protect a mountain weather station.

What happened at the station?

Read the notes about the mountain weather station. Use the information to answer the questions.

Notes from Ridge Peak Station

At Ridge Peak Weather Station, Amina checked an outdoor thermometer each morning. A storm changed the station's work. Strong wind pulled the old cloth cover loose. Rain then reached the thermometer. The wet cloth covered some of the numbers, so Amina could not read the temperature clearly. The team decided to test materials for a new sleeve. The sleeve needed to keep rain out, bend around the thermometer tube, and let the numbers show.

The team cut equal-size samples and used the same tests. For the water test, they put 5 drops on each sample and counted how many drops reached the thermometer tube. For the bend test, they wrapped each sample around the same tube. For the visibility test, they counted how many of 5 printed dots could be seen through the sample. Their notes recorded these results: clear vinyl let 0 drops through, bent around the tube, and showed 5 dots. Waxed cloth let 0 drops through, bent around the tube, and showed 0 dots. Cardboard let 2 drops through, stayed stiff, and showed 0 dots. Felt let 4 drops through, bent around the tube, and showed 0 dots.

What happened after the wind pulled the old cover loose?
