Investigating Acidity
Learners classify liquids as an acid, base or neutral. They use purple cabbage juice as an indicator to test several liquids in order to group them as acids, bases or neutrals.
Curated OER
An Introduction to Acids and Bases
Students explore acids and bases. In this lesson about acids and bases, students do an experiment to test certain items to determine what they are. Students use cabbage and litmus paper as indicators. Students understand how to sort the...

Household Acids and Bases
Ninth graders complete an experiment to determine the pH values of a variety of common household substances. They use red cabbage to find the indicator colors of the pH range. They complete a data table that includes a prediction and...
Curated OER
Sometimes, solid + liquid = gas
Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...
Curated OER
Determining Acids and Bases
Young scholars test various liquids and identify as acids or bases. In this chemistry and pH lesson, the students use purple cabbage indicator to test a variety of teacher-provided substances, then bring in liquids from home to test...

Basically Acids
Base your lesson plan on acids and bases on an informative resource. The first installment of a five-part module on the science behind Harry Potter has individuals investigate acid/base chemistry with the use of invisible inks. They also...
Curated OER
Determining Acids and Bases
Students use purple cabbage indicator to test five know substances for acidic/alkaline balance. They discuss the safety precautions required both inside and outside a lab in handling acids and bases.
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...
Curated OER
The Acid Test
Students prepare a test solution whose color changes when an acid or a base is added. They determine whether various household substances are acids or bases and look for patterns in the results. Students determine how their test solution...
Curated OER
Mixtures
Sixth graders experiment with mixtures. In this chemistry activity, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
Curated OER
HOW IS PH DETERMINED?
Students 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.
