Thermometric Titration Involving Dataloggers
In this thermometric titration learning exercise, students determine the concentrations of hydrochloric acid and ethanoic acid using a titration where they measure the temperature of the solution as they titrate. The equivalence point is...
Curated OER
Neutralization
Ninth graders study pH, acids, bases, and neutralization. They discuss and apply principles of neutralization to everyday situations (bee stings, indigestion remedies, soil acidity, etc.). They carry out several experiments using acids...
Curated OER
Water Quality And pH
Students determine the pH level of water and its effect on aquatic plants and brine shrimp eggs. This is a three part lesson that leads the student through the development of an understanding of water pH. They form a hypothesis and are...
Curated OER
pH
Students test the pH of various solutions. In this pH lesson, students use litmus paper to test the pH of household solutions. They compare their results with book charts.

By All Indications
How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...
Curated OER
Determining pH
Students evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Students complete their own pH level experiment. Students go to the GEMS Alien Juice Bar website to...
