Teaching Kits and Models
|We loan core models and interactive kits to educators for use in formal and informal education settings. Below is a list of items currently available.
Please note: Contact Nicole (nkurtz@LDEO.columbia.edu) for information and to reserve a core model for loan.
|Cretaceous Impact Kit (ODP 171B)|
|Sixty five million years ago, a 10 km wide meteorite crashed into what is now Mexico’s Yucatan Peninsula, creating, a 177 km wide crater and mass extinctions across the globe. This kit contains materials for audiences to explore the core evidence for the impact.|
|Glacial / Interglacial Core Model (IODP 303)|
|Expedition 303 drilled cores from the North Atlantic that helped build a timeline of climate change over the last several million years of Earth’s history. This data has provided invaluable insight into the most recent “Ice Ages” or glacial periods of cold climate with a lot of land and sea ice, and warmer periods of little to no ice called interglacial periods.|
|Palmer Deep Core Model (ODP 178)|
|This model is a replica of a core retrieved in the Antarctic Peninsula on ODP Leg 178. It shows seasonal layers (laminae) composed of different diatom species that were deposited during the late Holocene and provides evidence for the changing climate and glacial retreat that took place in the region after the last ice age. This core section also contains a drop stone.|
|Saanich Inlet Core Model (ODP 178)|
|The sediment cored at Saanich Inlet off Vancouver Island, British Columbia contains evidence of catastrophic flooding events – called Jokulhlaups (Icelandic, o-kul-loop) that took place at the end of the Pleistocene and Early Holocene. This is when the Ice Age came to an end and increasing global temperatures caused glacial dams to form large lakes that eventually drained dramatically when the dams melted and broke. This core shows an abrupt 30cm layer of silty clay containing preserved pollen and freshwater microfossils (diatoms and silicoflagellates) whose source can be traced back to glacial lakes 200km inland. This layer is positioned between two laminated layers of mud containing marine microfossils.|
|Tahitian Sea Level Change Core (IODP 310)|
|Expedition 310 collected evidence of changes in sea level during the last deglaciation, including a record of temperature and salinity changes in the southern Pacific. The two 60cm replicas of 310-20A-22R-2 display coral sandstone and massive coral (Porites) in growth position with interbedded microbiolites (organosedimentary deposits). Cavities are filled with Halimeda (calcareous algae) segments, gastropods, bivalves and microbiolites.|
Just getting started?
Whether you are teaching about cores, specific geologic events, or the process and nature of science, these resources will meet your needs:
- Peak students interest and develop science skills by having them make their own observations and generate questions from core models. Use a simple sheet or What You See is What You Get to record.
- Follow up student observations with a short reading What is a Core? and the JR Time Machine video guide.
Activities that delve deeper into sedimentary core analysis:
- Core Understanding – Core Description and Lithostratigraphy will give students an opportunity to further develop their observational and interpretive skills using terminology and processes used on the ship.
- Talk about inquiry…in Inquiry into Sediment Cores students use authentic core images, data, and dichotomous key to plot the distribution of global marine sediments (they learn what the different types are too!) then make inferences about what controls their distribution.
- Your students will discover the motivation and impact of a coring expedition with the case study Window on Arctic Coring that focuses on the question Why drill there? and gets them thinking about science as an evolving process.
If it is hard rocks and oceanic crust you are after, try these with the Hole Story Poster Images!
- Core Section Curation involves using guides to catalogue and label core samples.
- Mineralogy and Petrology of Oceanic Crust provides whole thin section photos for students to examine and match to whole thin section photos.
- Or have students calculate Drilling Rates through Oceanic Crust
over a three-day period and calculate the Density of Oceanic Crust.
