Is Dilution the Solution To Pollution?
Young scholars demonstrate the meaning of dilution and concentration and how pollution can affect the water that you drink. They perform an experiment to calculate the final concentration and dilution factor of solutions. They record the...
Curated OER
work in pairs for the activities of this lesson which include researching and identifying butterflies, writing, and a brief oral presentation.
Students explore the concepts of rdioactive decay and dating. They generate a radioactive decay table, use their data to plot a decay graph, develop the concept of half-life, and then use the graph to find the age of a mummified seal in...
