Graham's Laws: Diffusion and Effusion of Gases
Students conduct a series of experiments to explore Graham's law. In this chemistry lesson, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.
Curated OER
Graham's Law Of Diffusion
Students demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during the...

Freezing Point Depression: Why Don’t Oceans Freeze?
Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions about...
Curated OER
Introduction to Gas Chromatography
Students analyze gas chromatograms and suggest various applications for gas chromatography.
Curated OER
Stoichiometry
Learners research chemical formulas and balance chemical equations. In this chemical equations lesson students complete a class activity on chemical equations and answer questions.
