Acid Rain Simulation

Students will create samples of "acid rain" in the laboratory, using a pH Sensor to quantify the change in acidity of the "rain water".

Combustion, Phlogiston and Oxygen: An Elemental Discovery

Observe the relationship between combustion and oxygen content in the surrounding air in a closed system and relating this experience to the discovery of the element, oxygen.

Introductory Colorimetry

Monitor the progress of a chemical reaction by measuring the amount of colored light absorbed by the solution as the reaction progresses.

Alka-Seltzer Revisited

Investigate the reaction of Alka-Seltzer^® tablets with water in an open system. Explain how some mass appears to be "lost."

High-Tech Titration

Use titration to discover the concentration of a solution of hydrochloric acid.

Ideal Gas Law

Understand the principles of the Ideal Gas Law and measure the amount of CO₂ gas created in a chemical reaction.

Exploring Temperature

All That Fizz: CO2 Gas

Measuring the amount of CO₂ gas produced during a chemical reaction of Alka-Seltzer tablets with water.

Classic Endothermic Reaction: Alka-Seltzer® & Water

Measuring the temperature change resulting from an endothermic reaction of Alka-Seltzer tablets with water.

Classic Exothermic Reaction: Steel Wool & Vinegar

Measuring the temperature change resulting from the exothermic reaction of steel wool with vinegar.

Boyle's Law

Changing the volume of air in a syringe 2 mL at a time and measuring the change in pressure that results.

Acids and Bases

Measuring the pH of various solutions and classifying those substances as acids, bases, or neutral solutions.
