Curated OER
Date a Rock!
High schoolers figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
Curated OER
Investigating the Uses of Backyard Bacteria
High schoolers discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
