Students observe cloud type and coverage, as well as other weather conditions over a five-day period and correlate these observations. Students make and test predictions using these observations.

In this activity from NOAA's Okeanos Explorer Education Materials Collection, learners investigate how methane hydrates might have been involved with the Cambrian explosion.

Students observe, sketch, and describe clouds on their own before learning to identify cloud types by comparing photos of different clouds to their sketches.
