Household Mysterious Chemicals
In this household chemicals instructional activity, students fill in 10 blanks with answers about testing household materials. Students must also fill out a data table about what color each material turns when placed in cabbage juice.
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.

Determining The pH Of Common Substances
Students use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.
Curated OER
Soil Buffering
Students observe the pH change of an acid mixture poured over soil in a filter. Since the buffering capability of soils differs, you may want to do this experiment with several different soil types.

pH
Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Learners test the pH level of many water samples.
Michigan Sea Grant
Water Quality
Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.
