Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

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...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Students analyze the chemical equation for the reaction between vinegar and baking soda. They observe that the gas produced in the reaction is also part of the products of the written chemical equation.

This lesson on stoichiometry demonstrates how to use a balanced chemical equation to determine the mass of a product given the starting mass of a reactant. [7:55]

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, students use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

Through informational text, interactive practice problems, video clips, and real-world application, students are introduced to the science of Stoichiometry.

Students learn the basics of writing and balancing the chemical equations of chemical reactions.
