    Gizmos Name: Date: Student Exploration: Water Cycle Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. This should NOT be word for word like another student. If so, you will need to redo the assignment Vocabulary: aquifer, condensation, evaporation, freezing glacier, melting, phase change, precipitation, reservoir, runoff, transpiration, waler cycle Prior Knowledge Question (Do this BEFORE using the Gizmo.) The xvaler thal comes oul of your faucet at home used to be in the ocean. How did the ivaler get from the ocean Io your waler faucet? Waler goes through lhe water cycle. it gets evaporated, then condenses into a cloud which then precipitates in the form of rain snow, hale sleet and many more. The water is deposited into fresh water rivers and it then gets transported to people s homes through pipe systems after it gets treated in order to be consumed. Gizmo Warm-up Waler on Earth is always in motion. These motions form a repealing circuit called the water cycle. The Water Cycle Gizmo allows you Io explore lhe different paths water lakes as it moves from Earth s surface to lhe atmosphere and back. 1. Click Oceans. Whal percentage of Earth's waler is found in lhe oceans? 97.25% 2. Click Atmosphere. How does the Sun cause water I o move from lhe oceans Io the atmosphere? Water gels transported into the atmosphere through evaporation where the water gets healed up and it rises into the atmosphere as vapor. 3. Click Clouds. How do clouds form? The evaporated water vapor gets cooled and condensed into small water droplets that form clouds. 4. Click Precip {rain}. ('Precip" is short for precipitation or water falling to Earth s surface ) What causes il I o rain? The water droplets get bigger and heavier, and then they drop onto the Earth in many forms RpeirMuntlnn fnr pdiinjqtlnn l lisp nnlv PuNlr. siiarlm nr nriRflnn nrRhlfittPil e> 9iwrj Fwilnrp. p.qrnlrn All rinhis rpsprupri

    like rain, snow, hail, and many more 5. Click Oceans again, and then choose the PATH tab. Because it has the same beginning and end. the path is a complete cycle. How many steps does this cycle have? It has around 4-5 steps. Activity: Getthe Gizmo ready: The water cycle • Select the SIMULATION lab. and click Reset Question: What are the parts of the water cycle? 1. Collect djt a: Create two water cycles using the Gizmo. Each cycle should have al least four steps and should begin and end al the same location. Choose any starting point from the list on the right. When the cycle is complete, choose the PATH tab and write the steps below. Cycle 1: Oceans atmosphere, clouds, percip(rain), vegetation Cycle 2: Reservoir. Industry, atmosphere, clouds, precip(snow) 2. Analyze: Use the information presented in the Gizmo to answer the following questions. A. What percentage of Earth s waler can be found in soil? B. What percentage of Earth s waler is stored in ice and snow? C. What percentage of Earth s freshwater is stored in ice and snow? D. What percentage of Earth's water is found in lakes? E. What is transpiration? (Hint: Click lhe Vegetation button.) 0.005% of water in soil 1.9% total water in ice & snow 68.7% of freshwater in ice & snow 0.009% of water in lakes Plants use their roots Io absorb water from soil, and release water vapor from their leaves in trans porta lion. About 70% of waler used by people is used for agriculture. In lhe United Stales 35% water is spent on agriculture but 50% is spent on industry. F. What human activity uses the most water worldwide? G. What human activity uses the most waler in the United States? Repraduclian rar educational use only. Puttie sharing ar paeUng prthlttietf. C 2020 Explare-eamlrg All rigr1s reserved
