Simulation Instructions for The Greenhouse Effect

Introducing the Simulation Steps 1-2 same Step 3: Go to: Select “Waves” from the simulation options. Describe what is depicted: a planet much like Earth, but with an atmosphere we can manipulate. Have students pull the Greenhouse Gas Concentration slider on the right down to the bottom—no greenhouse gases. Then have them click on the cloud button at […]

Guiding Question: How does human industry affect flows of Carbon in the Carbon Cycle?

Explaining the Model. This picture shows a carbon cycle. The objects (cow, tree, ocean, soil, etc) are carbon reservoirs [—a place where carbon is stored], the arrows represent carbon flows [—carbon moving from one reservoir to another]. This simulation allows the user to focus on different views of the carbon cycle (reservoirs only; natural flows; human […]

Guiding Question: Can climate change affect ocean currents?

Introduce North Atlantic Deep Water. Off the coast of Greenland in the North Atlantic, very cold, very salty water sinks down to the bottom of the ocean and slowly flows towards the Equator, this is called North Atlantic Deep Water, NADW. This sinking water is one of the major drivers of the Great Ocean Conveyor Belt. This […]

Guiding Question: What causes ocean currents?

Define the term current. A current is defined as water flowing in one direction across some time and distance. Review density of water in the ocean. When ocean water becomes warmer or colder or saltier the relative density of that water changes. These density differences cause the water to move. Explaining the models. Each of the 9 models involve a large […]

Guiding Question: Why are some liquids denser than others?

Explaining the model. This picture shows a large liquid filled tank in the center and a selection of liquid filled balloons to the right hand side and alternative liquid filled tanks to the left. In this simulation, different balloons can be placed into the tank of liquid in the center to see if and how the […]

Guiding Question: How does heat energy affect water and air?

*If you looked at the previous simulation activity, compare what you now know about water to air. Explaining the model. This investigation will use two tightly sealed bottles—one filled with water and one containing air. Both bottles are at room temperature. A lamp will provide heat energy to both bottles equally. Predict what will happen. What will […]
