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
Not So Neutral Views
Students explore ways to use indicators to distinguish between acids and bases. They conduct an experiment to model and discuss the harmful effect of acid rain in our living and non-living environment.

Christa's Lost Lesson: Effervescence
How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Biocomplexity Lab Activity: Measuring Water pH
Middle schoolers 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.

Antacid and Uncle Heartburn
Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

The effectiveness of Antacids
Students design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they determined...
Curated OER
Household Chemistry
Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...
