Blast from the Past

The Blast from the Past poster activities allow students to discover Earth’s history through hands-on activities and simulations. This poster’s vivid images and clear text portray the story of a large asteroid that collided with Earth sixty five million years ago at the present-day site of the Yucatan Peninsula in Mexico. This impact created the Chicxulub crater.

Microfossils: The Ocean’s Storytellers Poster

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.
