Curated OER
Introduction to Neutraliization
Learners explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid
directly through bubble formation and indirectly through indicator color changes.

Colorful Milk of Magnesia
Students explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.
Curated OER
Cabbage Juice Indicator
Young scholars experiment with household solutions and classify them as a base or acid. In this exploratory lesson students complete a lab where they test products to see if they are an acid or a base.
Curated OER
Water Ph
Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...
Curated OER
Household Chemicals
In this chemicals instructional activity, students review how to read chemical labels, define an acid-base indicator, and decide which way strong acids can be dangerous. This instructional activity has 15 short answer and 20 fill in the...
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.
Curated OER
Observing Buffers In Lakes, Ponds And Streams
Pupils observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.
Curated OER
Chemical Reactions
In this chemical reactions worksheet, learners determine if solutions are acidic, basic, or neutral. Students give reactions' molecular equations and ionic equations. This worksheet has 14 problems to solve.
Curated OER
What is pH and Why is it Important?
Students investigate acids, bases, and pH, and related this knowledge to the problem of acid deposition.
Creative Chemistry
Salts
For this salts worksheet, students read how salts are created and how different acids make different salts. This worksheet has one graphic organizer and seven short answer questions.
Curated OER
What is the Best Solution to Dye Easter Eggs?
Young scholars use red and blue litmus paper to determine the category of common substances. They then set up an experiment using vinegar, water, and ammonia (or milk of magnesia) to determine that acids make the best solution for dyeing...
Curated OER
Determining pH
Young scholars evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Young scholars complete their own pH level experiment. Students go to the GEMS Alien Juice Bar...
Curated OER
Soil Sample Lab
Learners test the pH of soil samples they collected from the field trip. In this chemistry lesson, students differentiate acids and bases. They write a lab report about the experiment.
Curated OER
Natural Indicators: How Do They Work?
Pupils describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students observe...
Curated OER
Biocomplexity Lab Activity: Measuring Water pH
Young scholars test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.
Curated OER
CLEAN AIR ACT (1990)
Students investigate the effects of acid rain by conducting an experiment with bean sprouts and graph the results. In this Environmental Policy lesson plan, students visit a museum to identify examples of foreign and domestic policy on...
Curated OER
The pH scale
Young scholars 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...
Curated OER
Making A Natural pH Indicator
Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.
Curated OER
Invisible Ink
Pupils wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.
Curated OER
Acid Base Neutralization Problems
In this acid base learning exercise, students calculate the concentration of solutions as products of acid and base reactions. This learning exercise has 9 problems to solve.
Curated OER
Acid Base
In this acid and base instructional activity, students review the characteristics of acids and bases, how to calculate pH of a solution, and define a buffered solution. This instructional activity has 16 multiple choice questions and 3...
