Curated OER
Introductory Lesson on How pH Levels are Determined
Students explore pH levels of different substances. In this lesson about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to determine...
Curated OER
What is pH and Why is It Important?
Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...
Curated OER
pH and Red Cabbage Juice
Students review properties of materials and define what pH tells them about matter. In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.

Explore: 5th Grade Dissolved Oxygen
Fifth graders, in groups, use basic science process skills to measure and compare the dissolved oxygen levels and pH levels of distilled, stream, and pond water.
Curated OER
HOW IS PH DETERMINED?
Pupils estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

Acids and Bases: Cabbage Juice Indicator
Fifth graders perform tests to identify acids and bases. In this chemistry lesson, 5th graders identify common household substances as acids or bases using cabbage juice indicator strips.

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...
Curated OER
The pH scale
Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.

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...

Neutralizing Acids and Bases
Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...
Curated OER
Sense of Scale
Students examine the pH scale. They research common products and determine their pH level. They create their own pH scale and place their products in the appropriate place.

Understanding the pH Cycle within the Aquarium
Students discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...
