Students learn basic geological concepts while researching how ice age floods sculpted the plateau of the Columbia Basin. They synthesize their learning by creating annotated illustrations of the geological principles they studied.

How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...

Students investigate how the age of sedimentary strata is determined. In this sedimentary strata lesson plan, students work through problems that show that geological history covers millions of years. They distinguish between relative...

Arctic sea ice reflects 80 percent of sunlight, striking it back into space; with sea ice melting, the world's oceans become warmer, which furthers global warming. These activities explore how humans are impacting ecosystems around the...
