3. Why does water that evaporates from a puddle or lake eventually return to Earth, and what role does temperature play in this process?

4. Explain what "collection" means in the water cycle and identify two major places where water collects on Earth.

---

## **APPLY**
*Cognitive Goal: Use water cycle knowledge to solve problems and make predictions*

1. A puddle in your driveway disappears after a hot, sunny day with no rain. Use your knowledge of the water cycle to explain what happened to the water.

2. If a scientist wanted to speed up the water cycle in a closed terrarium, what could they change about the environment to increase the rate of evaporation and condensation?

3. A town's water supply comes from a mountain lake. Using the water cycle, trace the path that water takes from the lake, through the environment, and back to the lake.

4. During winter in a cold climate, frost forms on grass overnight even though it didn't rain. Apply your understanding of condensation to explain how this occurs.

## **ANALYZE**
*Cognitive Goal: Examine components of the water cycle and break down relationships between stages*

1. Compare and contrast how evaporation from an ocean differs from evaporation from a freshwater lake in terms of what substances are left behind and why this matters.

2. Analyze the cause-and-effect relationship between increased global temperatures and changes to the water cycle, including impacts on precipitation patterns.
