There's NOse accounting for taste! Or is there?
Materials

Materials Needed


  • small cups
  • cotton swabs
  • different foods with similar textures (the ZOOMers compared ketchup, mustard, barbecue sauce, sweet and sour sauce, and maple syrup.)
  • pen and paper for charting

Instructions

Instructions


  1. Check with a grown-up before you get started to make sure it's okay to taste some different foods in your house.
  2. Ask a friend to help. One of you will be the taster and the other the tester, but you can switch at the end so both of you will get a chance to taste.
  3. Draw a chart for recording your results. Write the name of each food you are testing in separate rows along the left side. Draw two columns for each taster. Label each column with the taster's name and "unplugged" or "plugged."
  4. Make some predictions about which foods will be easier and harder to identify. Will it be easier or harder to taste the foods with your nose plugged or unplugged?
  5. Blindfold the taster or just have her close her eyes.
  6. The tester then puts a little bit of one food on the taster's tongue with a cotton swab.
  7. The taster tries to identify which food she's tasting as well as whether it is salty, bitter, sweet or sour.
  8. The tester records the taster's answers on the chart for each food she tastes.
  9. When the taster has tried all the foods blindfolded, have her taste them each again but with her nose plugged as well. (Make sure you have her taste the foods in a different order.)
  10. Once the taster has tried each food with her nose plugged, switch who tastes and who tests and go through it all again.
  11. When you've both had a chance to taste, compare your results.


Which way was more challenging, with just eyes closed or with nose plugged too? Were certain foods especially hard or easy to taste? Try it again with crunchy foods or liquids and be sure to send your results to ZOOM!
Are you hot on the scent of the sci scoop? Here's how this works: A lot of what we think is taste is actually smell. That's why, when your nose is plugged, you can't taste some of the foods. It's because you can't smell what you are tasting.

Plugged and Unplugged I used my taste buds and it seems like I did better w/ my nose unplugged. I tasted peach baby food, pear baby food, apples, pears, Vanilla pudding, and banana pudding.

I found that I could taste the foods better if I could smell them.

Olivia, age 11 of Pleasant Grove, AL wrote:
I found out that it is easier to tell what condiment is in front of you by taste. But first you smell 4 condiments, and then taste them. And that will tell you that most of the time taste is better than smell.

I found out that the tasting worked better than the smelling. I didnt make them plug their nose, but it still worked!!!

Stevie, age 10 of Riverside, CA wrote:
I only did three things and I got all of them right, but I got the ones with my nose un-plugged. I got the answers much faster than when my nose was plugged.

The taste beat the smell. I did my experiment for a science fair project I used honey, honey mustard, ketchup, Hot mustard, ranch, sweet n' sour sauce, Buffalo sauce, and Barbeque sauce.

Audrey, age 9 of Ogden, UT wrote:
We tried it with different flavors of soda, cola, lemon lime, orange, root beer, grape, red cream soda. I thought that tasting it without smelling would be easier but most people guessed it while smelling only instead of tasting. It was a fun science fair experiment.
