Activity #20 Tear An Aluminum Can In Half
Students observe the chemical reaction between CuCl2 and aluminum. They identify the evidence for a chemical change. Pupils answer the following questions after observing the experiment: How do you know a chemical reaction occurred?,...
Curated OER
Ammonium Nitrate - Heat of Solution
Students quantify the relationship between temperature, energy and heat
and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.
Curated OER
Chemical Changes by Gems
Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.
Curated OER
Chemical Volcano
Students observe a demonstration performed by the teacher. They examine of a series of acid/base reactions and discover how various indicators work.
Curated OER
Iron Filings
Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...
Curated OER
Determination of a Rate Law
High schoolers determine the rate law for a chemical reaction. They use graphical techniques in the analysis of experimental data.
