Description
Today students completed our Convection Lab. They filled a tub with tap water; underneath was a sequence of Styrofoam cups filled with hot or cold water. Then they added a small scoop of potassium permanganate (food coloring works too!) above each of the cups. Before long, the water began to move. The difference in temperature caused the formation of convection currents. As the water molecules gained energy, they spread out, becoming less dense and rising to the surface. Then the water cooled off, becoming more dense and sinking back to the bottom of the tub. Convection will be an essential part of Unit 6. It happens in the ocean, in the air, and even underground. Hopefully this lab gives students a solid foundation for understanding all of Earth’s convection systems. (To see a video of the lab, please click here.)

NGSSMS-ESS2-3
Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Examples of data include similarities of rock and fossil types on different continents, the shapes of the continents (including continental shelves), and the locations of ocean structures (such as ridges, fracture zones, and trenches). Paleomagnetic anomalies in oceanic and continental crust are not assessed.
NGSSMS-ESS2-2
Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales. Emphasis is on how processes change Earth’s surface at time and spatial scales that can be large (such as slow plate motions or the uplift of large mountain ranges) or small (such as rapid landslides or microscopic geochemical reactions), and how many geoscience processes (such as earthquakes, volcanoes, and meteor impacts) usually behave gradually but are punctuated by catastrophic events. Examples of geoscience processes include surface weathering and deposition by the movements of water, ice, and wind. Emphasis is on geoscience processes that shape local geographic features, where appropriate.
NGSSMS-ESS2-1
Develop a model to describe the cycling of Earth’s materials and the flow of energy that drives this process. Emphasis is on the processes of melting, crystallization, weathering, deformation, and sedimentation, which act together to form minerals and rocks through the cycling of Earth’s materials. Assessment does not include the identification and naming of minerals.
NGSSMS-ESS2-4
Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity. Emphasis is on the ways water changes its state as it moves through the multiple pathways of the hydrologic cycle. Examples of models can be conceptual or physical. A quantitative understanding of the latent heats of vaporization and fusion is not assessed.
NGSSMS-ESS2-6
Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates. Emphasis is on how patterns vary by latitude, altitude, and geographic land distribution. Emphasis of atmospheric circulation is on the sunlight-driven latitudinal banding, the Coriolis effect, and resulting prevailing winds; emphasis of ocean circulation is on the transfer of heat by the global ocean convection cycle, which is constrained by the Coriolis effect and the outlines of continents. Examples of models can be diagrams, maps and globes, or digital representations. Assessment does not include the dynamics of the Coriolis effect.
