Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the buffering ability of sea water.

Quality Control at Kality Krunchers Dill Pickle Factory
In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the instructional activity requires the use of significant figures and calculation of percent error.

Identifying and Explaining Reactions
Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in vinegar, decomposition of ammonium chloride, and the mixing of iron with sodium chloride and water.

Matter and Energy
Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another activity, they examine product labels to find commonly used elements and compounds.

Half Equivalence Point
Sal reviews exactly what an "Equivalence Point" is, and what it means. He constructs two graphs; one uses a stronger acid than the other, and demonstrates how to determine the "Half-Equivalence Point," which is the point where the acid and the base present in the solution are exactly equal to each other.

Acid Base Problems
The pH, concentrations, and formulas are needed to complete this worksheet. Pupils should be able to list physical and chemical properties and then provide definitions and equations for common bases and their reactions. Space is provided for equations of dissociation and for the graphs for the titrations given.

Oxidation of Ethanol to Ethanal
Here is a laboratory exercise where chemistry masters carry out an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. Definitely aimed at learners experienced in the laboratory, this activity concludes by having them determine what type of reactions have taken place, describe the nature of the ethanal, and write chemical equations for all of the reactions that occurred in the process.

pH Indicators And Tests for Acids And Bases
Young scholars create various pH indicators and test unknown solutions to determine if they are an acid or a base. After the experiment, students take a quiz, found on a website imbedded in this lesson, on what they observed and discovered.

Infectious Disease Detectives
Students participate in a simulation of how diseases are transmitted. Each student holds a test tube, with only one containing the "disease" while the others have water. They move around the room until told to stop. Using droppers to place some of their solution into their neighbor's tube, they are spreading the disease.
