Activity 01
Demonstration: Mantle Convection Currents
Pour coloured corn syrup into a heatproof dish and gently heat one side. Add sprinkles to track movement as hot syrup rises and cooler syrup sinks. Pause to let students sketch currents and link to plate motion. Conclude with class discussion on surface effects.
Explain the basic forces that cause the Earth's surface to move.
Facilitation TipDuring the Mantle Convection Currents demo, circulate with a heat-proof glove so you can pause and point to rising and sinking fluid to anchor students’ observations.
What to look forProvide students with a world map showing major earthquake and volcano zones. Ask them to draw arrows indicating the general direction of movement between two landmasses and write one sentence explaining what might happen at their boundary.
