Weather and climate change

Lab 5 - Experiment 1: Modeling the Water Cycle

Hypothesis:

Post-Lab Questions

1. Restate your hypothesis. Was it confirmed or denied? How do you know?

2. Which water cycle processes are represented in this model and by what components?

3. Which processes are not represented? How could the model be altered to include these processes?

4. How would the “weather” be affected if the water was at a decreased temperature? What about at an increased temperature? How could you model these changes in this system?

Lab 5 - Experiment 2: Assessing Infiltration

Hypothesis:

Post-Lab Questions

1. Restate your hypothesis. Was it confirmed or denied? How do you know?

2. What formed on the inside of the bags? What parts of the water cycle are represented in this experiment?

3. What condition showed the greatest change? What force contributed to this change?

4. How would increasing the proportion of land (sand) to water affect the amount of water vapor released?

5. How would drought conditions impact infiltration and condensation from the ground?
