GizmosName:HunterDate:Student Exploration: Carbon CycleDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Vocabulary:atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geospheregreenhouse gas. hydrosphere, lithosphere, photosynthesisPrior Knowledge Questions(Do these BEFORE using lhe Gizmo.)Inthe process ofphotosynthesisplantslakeincarbon dioxide (CO.) from lhe atmosphere and waler(HjO)from lhe soil. Using the energy of sunlight plants build molecules of glucose (C HOe) and oxygen {O2).1.Howdo plants on Earth affect the amounl of cartoon in Earth's almosphere?They take carbon and turn it into oxygen.2.Animals eat plants and produce carbon dioxide and waler. How do animals affect the amounl of carbon inEarth's almosphere?They breathe out cartocn dioxide for the plants.Gizmo Warm-upTheCarbon CycleGizmo allows you Io follow the many paths an atom ofcarbon can take through Earth s systems. To beginnolice the black carbonatom in the Atmospheric CO=area, highlighted in yellow. The glowing blueareas represent possible localions lhe cartoon atom could go next.1.From Earth’s atmosphere, where can the cartoon atom go next?It could go to oceanic CO2next.2.Click on Land plants and read the description. How did the carbon atom get from the almosphere to aplant?The carbon gels Io the plant through photosynthesis.3.Select Land animals. How did the carbon atom get from land planIs into lhe animal?Animals consume plants, however a lot of carbon isn'tconsumed fromtheplant because it is storedin lhewood.4.Select Atmospheric COj How didlhecarbon atom gel from land animals back tolheatmosphere?

In a process called cellular respiration the animal breathesoul water and CO2 into the atmosphere.Activity A:Get lhe Gizmo ready:Carbon pathways•Click Reset.Introduction: Earth can be divided into four systems. The atmosphere is the air above Earth's surface. Thehydrosphere is composed of all of Earth's water. The geosphere is lhe rocky, non-living part of Earth. Thebiosphere consists of all living things, including people. Some scientists use the term "anthroposphere" todescribe everything made or modified by humans.Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere?1.Explore: Use the Gizmo Io create a path for cartoon that begins and ends in the atmosphere. Fill in lhesteps in the path below. Then, label each location with lhe system it represents. Finally, summarize verybriefly how lhe carbon atom got to that location.Cartoon pathSystemHow it got thereAtmospheric CO21AtmosphereAtmospheric CO2comes from volcanoes,burning fossil fuels, and other sources.oceanic CO2IhydrosphereCarbon dioxide dissolves in coldocean surface waters.Marine plants/algae1hydrosphere,biosphereIn the process of photosynthesismarine plants remove carbon dioxidefrom lhe waler.sediments1geosphereuneaten plants and algae drift downto lhe ocean floor and becomemarine sediments.petroleum1geosphereas sediments are compressed andheated, over millions of years,petroleum and natural gas areformed.

petroleum and forming carbondioxidevolcano1geospheredeep in earth's crust, rocks areheated Io high temperalures andmelted. This causes carbon dioxideto be dissolved in magma belowvolcanoes.2.Create: Click Reset Use the Gizmo Io create a path in which lhe carbon atom goes from the atmosphereto the hydrosphere, biosphere and geosphere. Describe each transition briefly.AtmosphereHydrosphereBiosphereGeosphereAtmospheric CO:oceanic co2■■Kmarine plants“*■sedimentsVolcanoes, burning fossilfuels, and olher sources.??3.Explore: Use the Gizmo Io create three more carbon paths, each starting and ending in the atmosphere.Label each location with A for atmosphere. B for biosphere. G for geosphere, or H for hydrosphere. {Youcan also use P foirthe anthroposphere if you like,orjust includeilinthebiosphere.)Path 1:Atmospheric (A), land planls (B).

Atmospheric CO2 (A).4.Explain: Based on lhe Gizmo, explain how lhe following transitions might take place:A.Describe at least two ways that carbon can gel from a land planl to the atmosphere.1.II could turn into a forest fire and become part of lhe sial. Ihen moving tosediments then Io natural gases. Ihen back inIo the atmosphere.2.it could go into coal, then a power plant then go back into the air.B.Describe at least two ways that carbon can gel from lhe almosphere Io the hydrosphere.1.II could be in the air and Ihen go into the ocean.
