Weather Detectives Grade 5

Warm winter winds, the hottest spot in the schoolyard and the last frost of spring. Students measure weather fairly and find out why farmers care so much about it.

• Why does a chinook feel like spring in January? 50–60 min

  Students test how moving air speeds up melting, then use a tabletop mountain and a few simple numbers to follow a parcel of air over the Rockies and find out why it arrives warm. They compare the chinook with similar winds around the world.

• Is it hotter by the slide? 50–60 min

  Teams take thermometers into the schoolyard and measure the air temperature at the same spots, the same way, to find the warmest and coolest places. They learn why a fair measurement matters and explain the differences they find.

• Why do farmers care about the last frost? 50–60 min

  Students compare frozen and fresh lettuce leaves to see what frost does to a plant, then use frost dates to work out the growing season in their own town and decide which crops have time to grow. They give planting advice backed by data.
