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 = the represented water cycle process in the model was evaporation. The component was the evidence of condensation on the lid.

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

Answer = the processes not represented are surface run-off, infiltration, transpiration, precipitation, sublimation and percolation. The model can only be altered to include these processes if the experiment is changed and additional supplies used.

3. How would the “weather” be affected if the water was at a decreased temperature? What about at an increased temperature?

Answer = with decreased temperatures, it affects the weather by slowing down the process and increased temperatures speed up the processes.

Experiment 1: Water Movement

POST LAB QUESTIONS

1. Develop a hypothesis predicting the effect of sunlight on evaporation?

Hypothesis = The process of evaporation is rapidly increased when there is a high heat temperature.

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 = I would accept my hypothesis because the water evaporated faster from the bag of sand left in the sun than the bag in a shaded area.

2. What parts of
