Curated OER
Introduction to Neutraliization
Pupils 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.
Curated OER
Sour Acids and Bitter Bases
Students explore acids and bases. They experience the sour taste of acids and the bitter taste of bases by tasting substances such as chocolate, lemon juice, and baking soda. in addition, they complete a worksheet for individual assessment.
Curated OER
Acids, Copper, and Zinc
Middle schoolers observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.
Curated OER
Chemical Weathering
Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Acid and Base Testing 2
Students design and conduct an experiment on unknown solutions after studying descriptions of indicators and the way in which they identify acids and bases. Students must gather, organize, and analyze data as well as make inferences...
Curated OER
Soiled Again
Students propose and perform an experiment using the scientific method. The purpose of the experiment is to discern some earth materials or combinations of earth materials that best increases the pH of "acid rain". From the results of...
Curated OER
Acidity of Soda Pop
Young scholars conduct an experiment to determine the acidity of three different brands of soda by adding a known volume of base until a pink color appears in the reaction vessel. They test fresh and flat soda, observe any differences,...
Curated OER
Every Breath You Take
Students study acids and bases and the uses of indicators. They interpret the actions of an indicator to conclude that bromothymol blue turns yellow in the presence of a weak acid.
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
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.
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
What is pH and Why is it Important?
Students investigate acids, bases, and pH, and related this knowledge to the problem of acid deposition.
Curated OER
Investigating Acidity
Students 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
Making Soap
Students recognize and use chemical indicators in the lab, recognize the need for safety while doing chemical experiments and understand the need for following precise directions.
Curated OER
Acids & Bases: What's the Solution?
Students conduct an experiment called "What's the Solution? Acid, Base or Neutral." to determine the differences between these types of substance.
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.

Determining The pH Of Common Substances
Learners use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.
Curated OER
Titration Lab
Students determine the concentration of an unknown solution using titration. In this chemistry lesson, students explain the difference between acids and bases. They discuss the role of indicators in titration.
