 Science Grade 8
Unit 5: Cycles of Earth Activity 2: Rate of Water Movement in the Water Cycle (SI GLEs: 2, 3, 4, 11, 13, 14, 19, 21, 22; ESS GLE: 24)
CC: Assign the students various climatic regions of Earth to research (e.g. tropical, dry, polar, mild, continental, high elevation). The students should locate climatic data that is quantitative such as; annual rainfall, average temperature, average length of daylight hours, topographic features, vegetation coverage, and the average amount of insolation for the chosen region. The students should interpret the data to determine if water is abundant in the region as well as if evaporation rates would be high or low because of the amount of solar radiation the region receives throughout the year. The students then infer reasons why the water cycle might be either enhanced or impaired in this climate region. Ask students why their reasons are inferences and not observations.
