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 = On the lib Condensation is represented and because there is condensation, evaporation must have happened. 2. Which water cycle processes are not represented? How could the model be altered to include each of these processes? Answer = All of the other processes are not representative. Sublimation, Precipitation, Transpiration, surface run off, infiltration and percolation. 3. How would the “weather” be affected if the water was at a decreased temperature? How would the “weather” be affected if the water temperature were increased? Answer = If the weather decreased in temperature, it would have less condensation on the lid because the temperature would have been less and the water would have no evaporated. Experiment 1: Water Movement POST LAB QUESTIONS 1. Develop a hypothesis predicting the effect of sunlight on evaporation? Hypothesis = The sunlight will make the water evaporate at a faster speed 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 = I would accept, the reason for me accepting my hypothesis is because when the heat was placed the water began to evaporate quicker. 3. What parts of the water cycle are represented in this experiment? Answer = condensation, evaporation and precipitation. 4. How would increasing the proportion of land (sand) to water affect the amount of water vapor released? Answer = I think by increasing the proportion of land (sand) you would find
