Respond to the questions andprompts in the orange boxes.This should NOT be word for word like another student. Ifso, you will need to redo the assignmentVocabulary:aquifer, condensation, evaporation, freezing glacier, melting, phase change, precipitation,reservoir, runoff, transpiration, waler cyclePrior Knowledge Question (Do this BEFOREusing the Gizmo.)Thexvaler thal comes oul of your faucet at home used tobein the ocean.

The water is deposited intofresh water rivers and it then gets transported to people s homes through pipe systems after itgets treated in order to be consumed.Gizmo Warm-upWaler on Earth is always in motion. These motions form arepealing circuit calledthewater cycle. TheWater CycleGizmoallows you Io explorelhedifferent paths water lakes as it movesfrom Earth s surface to lhe atmosphere and back.1.Click Oceans.

How do clouds form?The evaporated water vapor gets cooled and condensed into small water droplets that formclouds.4.Click Precip{rain}.('Precip" is short for precipitationor water falling to Earth s surface ) What causes ilI o rain?The water droplets get bigger and heavier, and then they drop onto the Earth in many formsRpeirMuntlnn fnr pdiinjqtlnnl lisp nnlvPuNlr. siiarlm nr nriRflnn nrRhlfittPile>9iwrj Fwilnrp. p.qrnlrnAll rinhis rpsprupri

like rain, snow, hail, and many more5.Click Oceans again, and then choose the PATH tab. Because it has the same beginning and end. the pathis a complete cycle. How many steps does this cycle have?It has around 4-5 steps.Activity:Getthe Gizmo ready:The water cycleSelect the SIMULATION lab. and clickResetQuestion: 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 andshould begin and end al the same location. Choose any starting point from the list on the right. When thecycle is complete, choose the PATH tab and write the steps below.Cycle1:Oceansatmosphere, clouds, percip(rain), vegetationCycle 2:Reservoir. Industry, atmosphere, clouds, precip(snow)2.Analyze: Use the information presented intheGizmo 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 andsnow?D.What percentage of Earth's water is found in lakes?E.What istranspiration?(Hint: ClicklheVegetation button.)0.005% of water in soil1.9% total water in ice &snow68.7% of freshwater inice & snow0.009% of water in lakesPlants use their roots Ioabsorb water from soil,and release water vaporfrom their leaves intransportalion.About 70% of waler usedby people is used foragriculture.In lhe United Stales 35%water is spent onagriculture but 50% isspent on industry.F.Whathumanactivity usesthemost water worldwide?G.
