  1. Flavor Detective What Happened? Adapted from Shirley Wilborne 2002

  2. Smell & Taste Tongue – only sense 5 tastes – • Saltiness • Sweetness • Sourness • Bitterness • Meatiness (umami)

  3. Nasal Passages Can respond to 1000s of different molecules

  4. How we sense taste… • Tongue tastes • Nose smells • Texture • Temperature

  5. Taste is Mostly Smell • Tongue can’t tell the difference between orange and lime. • Nose detects difference • With a cold – onions and apples taste the same

  6. So… why were you able to taste the difference between flavors • May inhale as we swallow, allowing the nose to smell the flavor.

  7. Great Activity for learning how to design experiments.. • Selected jelly beans from the cup without the subject knowing which ones • No feedback increases success of experiment – “blind test” • In drug testing – double blind – the person giving the meds doesn’t know what they’re giving

  8. Control Group • The group of trials need for comparison • No eyes, using nose before the study to compare results with the experimental group. Scientists don’t assume to know what “normal” is. They collect data to be sure.
