Lab 5 – Weather and Climate Change
Lab 5 - Demonstration 1: Modeling the Water Cycle
POST LAB QUESTIONS
1. Which water cycle processes are represented in this model and by what components?
Answer = Warm water evaporated into water vapors that were trapped under the lid. After evaporation it returned to water. These processes are called evaporation and condensation.
2. Which processes are not represented? How could the model be altered to include these processes?
Answer = The following processes were not represented which were transpiration, surface run-off, infiltration, and percolation.
3. How would the “weather” be affected if the water was at a decreased temperature? What about at an increased temperature?
Answer = If the temperature was lower the water would evaporate slower as warmth would allow it to move or evaporate quickly.

Experiment 1: Water Movement
POST LAB QUESTIONS
1. Develop a hypothesis predicting the effect of sunlight on evaporation?
Hypothesis = Water inside the bag in the warmer temperature will evaporate quicker. The bag placed in the sun has more precipitation at the top of the bag than the bag in the shade.
2. Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this.
Accept/reject = The hypothesis was accepted as the bag in the sun had more precipitation at the top of the bag than that one in the shade.
3. What parts of the water cycle are represented in this experiment?
Answer = Evaporation, Condensation, & Precipitation
4. How would increasing the proportion of land (sand) to water affect the amount of water vapor released?
Answer = If there was more land more water could be stored in the sand. The sun would then heat up the sand and dry out the sand. This would cause the water to evaporate.

5. How would drought conditions impact infiltration and evaporation from the ground?
Answer = The land would dry up due to the lack of water as there would not be any rain.
