Biocomplexity Lab Activity: Measuring Water pH
Students 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
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...

Acid Rain Lesson Plan Activity 2 - Understanding the Difference Between an Acid And a Base
Young scholars 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
Number Base
Eighth graders examine common number system bases that are used: decimal, binary, octa and hex. They create a presentation about one of the number systems using the internet to research the topic. They solve mathematical computations.
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
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
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.
