Scientists can learn about past environmental conditions of the ocean by looking at microscopic organisms called foraminifera (fawr-uh-min-uh-fer-uh). Foraminifera lived in very specific salinity, temperature, and depth conditions in the ocean. By taking a core sample from the ocean floor and observing the fossilized foraminifera, we can learn about past environmental conditions. This investigation uses shapes to model the fossils, and attributes to give information about the fossil. An Information hand-out explains what each attribute means. Students use this information to write a story of their fossil record. Activity download costs $2.00.
