ACTIVITY 1 – GROUNDWATER SIMULATION MODEL.pdf

ACTIVITY 1 – GROUNDWATER SIMULATION MODEL Hypothesis: Humans have affected the hydrological cycle in a variety of ways including construction of dams, artificially draining aquifers, and deforestation. When contamination ends up in a well, it will spread to deeper areas of the ocean, and when contamination goes through lake areas, it stays more contaminated at the surface. Predictions: If the dye is injected into injection wells or Piezometers then the dye will move at a quick speed in a downward direction. If dye is injected into the leaky lagoon, artesian well, or lake it will move at a slow speed in a downward direction. PROCEDURE: RESULTS: 1. In which direction did the colored dye move? 2. How quickly did the movement of the dye take place? 3. Was the speed as which the dye moved different in different layers?

DISCUSSION: What is the overall point that you learned during the demonstration? (e.g. what is the take home message?). ACTIVITY 2 – FLOW OF ENERGY IN ECOLOGICAL SYSTEMS USING CALORIC CONSUMPTION Hypothesis: Caloric intake can affect the environmental temperature from high and low ambient temperature, and energy intake increases. Energy output also affects caloric intake. Prediction: If I where to perform my daily cardio this 24-hour caloric content tracker it would have a high caloric intake due to the amount of energy I exert in the day. Procedure 1. During a 24-hr period keep careful record of the foods that you eat and their caloric content. The labels of any food items should contain a list where you can find the calories (**Note that food calorie as given in the books and on labels is the kilocalorie). Use Table 1 to record your daily intake.

3. Now calculate your yearly energy intake and record this number in Table 1 and Figure 3. This is done by multiplying totals for each food (Table 1) by 365. You will need these subtotals for the rest of the activity, once you have multiplied each food by 365 sum up the results. Your gross energy intake ___________________ x 106 kcal/year 4. Now we can determine how much cropland is needed to supply your yearly caloric consumption (Table 2). This will be accomplished by adding the “Square meters of land required to support you” column. Cropland needed to support you __________________m2 5. The energy in sunlight is approximately 1.5 x 106 kcal/year at the earth’s surface. Multiply the square meters of land required to support you by 1.5 million to obtain the solar energy input to that land. Record value in Figure 3. Total solar energy: _____________________ kcal/year 6. Add up the square meters required to support you in the four categories: Cropland in C3 plants: ___________________m 2 Cropland in C4 plants: ___________________m 2 Cropland in plants fed to livestock: ___________________m 2 Ocean (continental shelf): ___________________m2
