Cholera and the Scientific Method
Five individuals in the class are "infected" with cholera! The rest of the class serves as investigators to discover the source of the outbreak. They test drinking fountains around campus for contamination. You, of course, will secretly...
Curated OER
pH and Red Cabbage Juice
Students review properties of materials and define what pH tells them about matter. In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.

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
Acid Attack
Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...
Curated OER
Weather, Sea Level Rise and Climate Change
Students compare the carbon dioxide content of four different samples. For this chemistry lesson, students research the causes of global warming. They explain how humans contribute to rising global temperature.
