For this project, you will write a paper that involves designing, conducting, and analyzing results from your own experiment to test the sensory discrimination of one of your friends. Choose a friend who claims to be able to tell the difference between two very similar objects. You are free to choose the two objects, however here are some ideas to get you thinking along the right lines: Coke vs. Pepsi, Regular vs. Decaf coffee, Sweet 'n' Low vs. Equal sweetener, butter vs. margarine, or Ghiradelli chocolate vs. Hershey’s chocolate. Which you choose depends on whoever your “expert” testing subject is. You will need to find an expert on your own, and will need to supply your own materials. The cost of your experiment will obviously depend primarily on the objects to be tested; testing to see if the subject can discern between bottled water and tap water will only cost a couple dollars, testing to see if the subject can discern between different brands of caviar will get pricey fast!
