Human Genetics Taste Paper Set

Test the genetically-determined taste response of students and families to three different chemicals. The set includes vials of PTC, sodium benzoate, thiourea, and control paper. Each vial contains 100 papers. The set also includes a reproducible family pedigree chart and teacher’s instructions. Replacement vials can be ordered separately. NOTE: Some school systems ban the placement of anything in the mouth during a science class or the use of PTC taste papers. Abide by your system's state and local regulations. If you cannot use PTC taste papers, you can investigate other human genetic traits, like earlobe attachment or the ability to roll your tongue (tongue rolling).
