This is a 3 page lab activity for testing pH of household substances. Page one is a blank pH scale where students need to write in the substances and their corresponding pH (based on testing). They also identify facts (characteristics) of acids and bases.
Page 2 has a color copy of Hydrion paper color changes for easy identification.
Page 3 is a test mat (that I suggest laminating for yearly use) that the students use to place their unknown substances and pH paper.
Can be used for chemistry and forensic testing.
