Curated OER
Chemistry: pH Probe
Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...
Curated OER
pH Testing
Students explore the use of variables in the scientific method. They identify the dependent and independent variables through pH testing. Students construct graphs of their data and analyze their findings.
Curated OER
Polluted Rain
Students identify and analyze how acid rain can affect the environment. They then explain how air, water, and pollution interact and conduct pH tests to find acidity levels in water. Finally, students become "Pollution Watch Reporters"...
