Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
The Water Cycle

Curated OER
Water World Story
Fourth graders write a story about how a drop of water may have traveled to school. They design a presentation on the water cycle.
Curated OER
Disappearing Water
Students observe the amount of water in an open container over time, and they observe the amount of water in a closed container over time. They compare and contrast the sets of observations over time.
Curated OER
Tree Bagging
Students bag trees to determine the mass of the water given off in the evapotranspiration process.
