These mini-lessons are designed to introduce young children to and encourage exploration of a variety of subjects related to the process and science of scientific ocean drilling. They can be used as a unit in any order; alternatively each lesson can stand alone.
The Glacial Interglacial Core Model contains evidence of a shift from an interglacial to a glacial period approximately 0.9 million years ago. This core can be loaned out for your educational needs.
This fossil fun game lets you match the shapes of tiny organisms as they fall to the ocean floor and become microfossils. Learn more about microfossils by reading the microfossil fact sheet. Watch your score and compare with friends as you make successful matches. A word of caution: this game may be habit forming!
Microfossils are microscopic single-celled organisms that belong to the Kingdom Protista (or Protoctista). Examples include calcareous nannofossils, foraminifera, diatoms, radiolarians, and silicoflagellates; planktonic organisms that inhabit the sunlit surface waters of the world ocean. The tiny shells of microfossils are the sediments that cover vast areas of the seafloor.
Seafloor spreading is one component of the theory of plate tectonics. At mid-ocean ridges in many of the world’s oceans, new sea oor rock is added to the edges of plates on either side of the ridge. We nd the youngest sea oor rocks near these ridges, where new sea oor is constantly added. As you move away from a ridge, sea oor rocks become increasingly older. One way geologists recognize the strips of sea oor…
