In this catalysts instructional activity, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

Why are acids and bases important in our daily lives? Lead the class in answering this question, among others, as they experiment with pH paper and classify where various substances belong on the pH scale. They also taste common acids...

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Fuel cells are being called the "energy source" of the future. Allow your high school chemistry class to construct a miscroscale fuel cell, complete with all components to generate energy. This engaging activity will allow them to apply...

How exciting would it be for your chemistry class to produce their own "gold"? This experiment allows pupils to witness the chemical reaction of copper pennies as they react with zinc and sodium hydroxide to produce "gold" tokens. It is...
