The Measurement Of Acids And Bases
Middle schoolers investigate the differences in chemistry between an acid and a base substance. They conduct measurements based upon the pH scale and then answer the questions included in the lesson. The information for the lesson is...
Curated OER
Strings and Things: An Investigation into pH
Students test the pH of everyday substances. For this chemistry lesson, students test the pH of household substances using litmus paper to classify substances as acids or bases, then use pH to test the validity of the claim that dock...
Curated OER
Determining Acids and Bases
Students test various liquids and identify as acids or bases. In this chemistry and pH lesson, the students use purple cabbage indicator to test a variety of teacher-provided substances, then bring in liquids from home to test acidity....
