Bouncing Popcorn
Third graders meet a teacher challenge to work like chemists. They investigate with baking soda, water, salt, sugar, vinegar, and sprite to move a popcorn kernel from the bottom of a cup to the top. They experiment with different...
Curated OER
Molar Ratio
Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...
Curated OER
Topic: Math, Chemistry, and Food
Learners listen as the teacher tells the story of Sisyphus rolling the stone up the mountain. Students prepare two batches of jello, one with fresh pineapple, and one with canned pineapple. While the jello is setting, learners work on...

Demonstrate Your Chemistry
Students research and evaluate chemical reaction demonstrations that are found on the web. they work in small groups to choose a demonstration that fits a particular category of reaction and then perform the demonstration for the class.
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
Coal Moisture Analysis
Young scholars investigate coal samples and analyze its drying loss under controlled conditions. They establish the loss in mass of a sample when heated under controlled conditions of temperature.

Acid and Bases - Alien II
Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.
Curated OER
Acid Precipitation
Students test the acidity of unknown solutions. They use this information to make inferences from data given from recorded rainfall records to identify areas that receive the most acid rain.
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.

Effect of Concentration of the Reactants
Students experiment to determine the effect of the frequency of collisions between atoms or ions of the reactants. They investigate the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid.
Curated OER
Physical vs. Chemical Change Lab
Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.
Curated OER
Determination of a Rate Law
Students determine the rate law for a chemical reaction. They use graphical techniques in the analysis of experimental data.
Curated OER
Energy of Activation
High schoolers determine the activation energy of a chemical reaction.
