Curated OER
Acids, Copper, and Zinc
Students 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...

Acidity of Soda Pop
Pupils 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, and draw...
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
Students 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?
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
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
Learners 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
Determining The pH Of Common Substances
Students 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
How Does Mining Produce Acid Runoff?
Students examine how mining and other industry operations can lead to acid runoff. In this mining lesson students study weathering and complete a lab on it.
Curated OER
Physical and Chemical Change
Students study the differences between physical and chemical changes. In this physical and chemical lesson students complete several labs to help them to see the differences between these changes.
Curated OER
The Physical Setting
Ninth graders study the configuration of atoms in molecules to see that it determines the molecule's properties. In this chemistry lesson students divide into groups and complete their assigned task.
Curated OER
Acids and Bases - Vinegar II
Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental lesson, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of unknown pH.
Curated OER
Vision Props of Signed Numbers
Students explore the concept of titration. In this titration lesson, students observe acid and alkaline reacting. Students discuss pH factor, measuring acidity, neutrality, and alkalinity of liquids. Students put the pH of liquids on a...
