Timeline
Students develop a timeline that depicts geologic development and the history of life. They write an interpretive analysis essay that discusses and reflects on their observations.
Curated OER
Radioactive Decay
Students generate a radioactive decay table for an imaginary element, use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.
