Curated OER
Acids and Alkalis
This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...
Curated OER
Acid Rain Environment Pollution
Students combine different materials to create chemical reactions. In this chemical reaction lesson plan, students will combine different materials to create chemical reactions and define these results as acids or bases. They will also...
Curated OER
Indicators For Acids and Bases
Fourth graders compare the color of cabbage water when acids and bases are mixed in. In this acids and bases lesson plan, 4th graders use cabbage water and mix in acids and bases that the teacher prepares before hand. They observe the...
Curated OER
pH Scale, acids and bases
Eighth graders define the pH scale, acids and bases. They distinguish between acidic and basic solutions using litmus paper. Students review simple chemical formulas. They define the subscript and coefficient in terms of chemical...
Curated OER
Acid Rain Lesson Plan Activity 2 - Understanding the Difference Between an Acid And a Base
Learners experiment to determine the difference between an acid and a base. They study the concept of adding a buffering agent to make an acid more basic. They study the pH scale.
Curated OER
Acid Rain And Geology
Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.
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.
Curated OER
Polluted Rain
Young scholars identify and analyze how acid rain can affect the environment. They then explain how air, water, and pollution interact and conduct pH tests to find acidity levels in water. Finally, students become "Pollution Watch...
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.

Serc: Investigating P H of Common Household Substances
Middle schoolers investigate the pH level of household substances by testing a variety of common compounds. Substances are tested with pH strips and placed on the continuum of the pH scale range of 1 to 14. After testing a solution, the...
American Chemical Society
Middle School Chemistry: P H and Color Change
Students see a demonstration of a color change using universal pH indicator and then change the concentrations of an acid and a base using a universal indicator to test the pH of the resulting solutions. Through an animation, they see...
