Curated OER
A Burst of Light
Students discover the many uses of minerals in industry. They use minerals to conduct flame tests and to demostrate color. They practice safety tips in the lab.
Curated OER
Straw Chromatography
Young scholars become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.
