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
Acid Rain And Geology
Pupils become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.
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.

Soil and Agriculture: Lesson 4 - Agriculture and Soil
Students determine how the various levels of minerals in the soil, as well as the pH of the soil, affect the growth of plants in these plant growth experiments.
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.

Acid Rain Research
High schoolers collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.
Curated OER
Water Quality
Students play the role of scientists testing for water quality in the area. In this ecology lesson plan, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the...
