Hello, I just need questions answered for the weather and climate lab. I've attached the protocols for the experiments also.

155 Weather and Climate Change Experiment 1: Modeling the Water Cycle In this experiment, you will construct a model of the Earth’s surface and atmosphere to explore how energy drives weather. Procedure 1. Using a graduated cylinder, carefully pour 20 mL of warm water (60 ° C) into canning a jar and secure the lid. 2. Fill the Petri dish with ice and place on top of the canning jar’s lid. 3. Observe the jar every five minutes for 30 minutes; after 30 minutes, remove the Petri dish and carefully remove the lid and observe the underside. Consider what processes are driving the changes you see and use your observation to answer Post-Lab Question 1.

Experiment 2: Assessing Infiltration In this experiment, you will observe how entrapped water moves from land to the atmosphere and determine how weather conditions affect this movement. Procedure 1. Use the permanent marker to label one re-sealable bag “sunny” and the other re-sealable bag “shady”. 2. Measure 100 mL of sand into each plastic re-sealable bag. Measure 100 mL room temperature water in each bag. Do not actively mix the sand and water in your bag. 3. Seal each bag, leaving a bit of air in each. 4. Place one bag in a sunny location and one bag in a shady location. 5. Observe the bags after one hour, then again after 12 hours. Record your observations in Table 1.
Pre-Lab Questions 1. Describe two ways by which weather affects the water cycle. 2. Research a weather phenomenon (e.g., hurricane, tornado, snow storm, etc.) and describe the atmospheric conditions that cause it. 3. List two natural processes that would be disrupted or not occur if there was no atmosphere and explain why. Experiment 1: Post-Lab Questions 1. Which water cycle processes are represented in this model and by what components? ©eScienceLabs, LLC 2015
2. Which processes are not represented? How could the model be altered to include these processes? 3. How would the “weather” be affected if the water temperature was decreased? What about if it was increased? How could you model these changes in this system? Experiment 2: Post-Lab Questions 1. What formed on the inside of the bags? 2. 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? ©eScienceLabs, LLC 2015
