GEOSPHERE
2A- Plates and Gates
This activity explores how plate tectonics affect ocean currents and biodiversity.
2B- Build a Model ANDRILL Drill Site
Students build a model drill rig and compare past environments represented by the sediment cores retrieved.
2C- Mix up a Model Rock Core
Learners create a model of an ocean sediment core with different sediment layers representing the presence of a grounded glacier, an ice shelf and open water.
2D- Mess Free Rock Cores
Students build models using photographs and paper towel tubes and then interpret various layers in sediment cores making inferences about climate change.
2E- When Ice Meets the Sea
Learners simulate the moving of a glacier from land to floating over the ocean creating an ice shelf and pressure ridge
2F- Dead Diatoms Do Tell Tales
Learners tell the story of climate change using the proxy of ice shelf advance and retreat by collecting data from simulated ocean bottom sediment cores.
2G– Evidence of Ice Free Seas
Learners create a sediment core model, collect date in the form of cool and warm water diatoms and then make inferences about changes in the ocean’s environment over geologic time.
