In this activity, students explore the sense of taste and write an argument with Claim, Evidence, and Reasoning to decide if they are a supertaster.
This activity includes 3 different tests for students to make a claim whether they are a supertaster, a taster, or a nontaster. In the first activity, students rate their level of taste of certain foods to reflect on their own personal taste ability/preferences. In the second activity, students see if they have the genetic ability to taste certain chemicals (PTC, PROP, etc). In the final activity, students color their tongues to see the papillae and count the number of papillae in a constrained area. After completing the 3 activities, students read a passage about the science of taste and then write an argument based on their observations and reading.
Blue food coloring
Hole punch reinforcement stickers
PTC, Sodium Benzoate, or PROP test paper strips*
*All 3 test strips are available at Amazon or Scientific Supply companies like Carolina. There have been some articles that have expressed concern over the use of PTC (the most commonly used genetic taste strips) the other two have been listed as safer alternatives.
There is a presentation and a set of student data sheets included in the activity. The presentation helps keep students focused on the right part of the activity.
