Embroidering Microfossils

Embroidering Microfossils

This pdf provides templates for many microfossils, however, there are hundreds of types not included here. You can find more images of microfossils at mikrotax.org. Disclaimer: These images are not to be scientifically accurate portrayals of each type of microfossil but rather as a template for creative expression. Because these were once alive organisms there was also quite a bit of variation in the way members of the same species would have looked. Materials Needed:…

The “Hole” Story about Ocean Cores

Lab groups can work together to examine high resolution photos and data from four cores taken at various depths in this first-of-its-kind complete section of oceanic crust. This poster includes background information and five classroom activities on the back.

Tahitian Sea Level Change Core (IODP 310)

The two 30cm 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.

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, pronounced 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…

PETM Core Model (IODP 208)

This core shows two time periods when a warming climate initiated a rapid release of carbon resulting in extreme ocean acidification.

Palmer Deep Core Model (ODP 178)

This model shows seasonal layers (laminae) composed of different diatoms 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.

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 with little to no ice called interglacial periods.

Cretaceous Impact Kit (ODP 171B)

General Introduction Cretaceous Impact Kit: Introduce the JOIDES Resolution research vessel and scientific ocean drilling Demonstrate how cores and sediment records drilled from the ocean floor can be used to make inferences about past events Present different careers associated with conducting science on the ship. Using the Cretaceous Impact Event to Teach Science Process Challenges students to make core observations and generate questions to obtain information that helps them make inferences about past events. Introduces…

Fault Core: 141 Triple Junction Core Kit

Faulted claystone, silty claystone, sandy silty claystone from late Pleistocene subunit IIC recovered from hole B at Site 863.  This site is located at the base of the trench slope of the Chile Trench where the Chile Ridge is being subducted.  One of the objectives of drilling at this site was to identify the structural fabrics and deformation caused by rift subduction.
