Someone has been mailing anonymous love letters to the captain of the football team and sealing each one with a kiss. He wants his fellow classmates to help him get to the bottom of this mystery. In this lab activity, students will use paper chromatography to compare the lipstick worn by each female suspect to that of the lipstick found on the envelopes. Students will then analyze the lip prints of each suspect in order to positively identify the “guilty” party. While completing this lab activity, students will employ Framework Science Standard PS1.

This kit has been aligned with all published National Standards. Pre- and Post-laboratory assessments and vocabulary words all target specific Science and Engineering Practices and common core standards.
