Do you need an activity to supplement your curriculum? Students will look at 20 scenarios and determine whether they are physical or chemical changes. The PDF version can be printed on cardstock, laminated for future use, and has a recording sheet. The digital (Google Sheets version) is self-checking. Students will input all their answers and click the 'Check Answer' checkbox to see which questions they got correct. Correct answers will turn green and incorrect answers will turn red. An answer key is included.
