Students investigate the inheritance of the ability to taste sodium benzoate by constructing a pedigree of the ability of members of their family to taste them. Includes: 1 vial sodium benzoate, 1 vial control papers (100 papers per vial), and a family pedigree chart. *Test Paper Factoid: Taste papers can be used to demonstrate inheritance. The ability to taste PTC is a hereditary trait. 7 out of 10 people will taste it. Sodium Benzoate tastes sweet, salty, bitter or will be tasteless to different people. Thiourea tastes bitter to most but is tasteless to some!

Includes: six each of marble, slate, and quartzite. Set of 18.

Common rocks and minerals for testing and identification studies are 2–3cm each.

Useful for teaching AP Biology units on Molecular Genetics.
