For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Students examine the different propereties of ice, such as freezing temperature.  In this scientific lesson students complete several activities using ice, like making ice cream.

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.

For this enthalpy of reactions learning exercise, students use a known amount of copper (II) sulphate solution and an excess of zinc powder to calculate the reaction's enthalpy change. Students measure the temperature change throughout...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

High schoolers collaborate in an experiment where they decompose water into simpler substances through the process of electrolysis. They collect, measure, and observe data and then place the data into a table. Accomodations for...
