small cups or glasses
unsweetened baking cocoa
pens and paper for charting
Ask a friend to help. One of you will be the taster and the other
will be the tester. When the first person is done tasting, you can switch so
both of you will get a chance to taste. Put a little bit of each substance
in a cup. Mix the non-liquids with some water so that all the substances have
about the same consistency. Draw a chart for recording your results. Along
the left side of the paper write each of the foods you will test in a separate
row. You can use unsweetened baking cocoa and water to test bitter, lemon juice
to test sour, honey to test sweet, and salt water to test salty. Across
the top draw three columns for each taster. Label each with the taster's name
and "front," "back," and "side." Make some predictions. Do you think
different places on your tongue will taste different flavors more intensely?
Where on your tongue do you think each flavor will taste strongest? Will some
flavors be easier or harder to taste than others? Have the tester
dip a cotton swab into one of the liquids and dab it either on the front, back
or side of the taster's tongue. The taster tastes the liquid, then
takes a sip of water. This helps clear your tongue of the taste so it doesn't
interfere with the next part of the experiment. The tester then dips a new
cotton swab in the same liquid and dabs it on a different part of the taster's
tongue. The taster tastes the liquid again and sips some water. Now, try it
again on the third part of the taster's tongue. Once all the parts of the
tongue have tasted the liquid, the taster says which part of his tongue tasted
the liquid the strongest. The tester records the taster's answer on the chart.
Follow the same process for each of the different liquids. Then switch who
tastes and who tests and do the whole taste test again with the new taster.
When all tasters have finished testing, talk about your results. Were your
predictions correct? Did some of your results surprise you? Did both tasters
taste the same things on the same parts of your tongues?

Taste VS. Smell
different foods with similar textures (i.e. ketchup, mustard, barbecue sauce,
sweet and sour sauce, maple syrup)
pen and paper for charting
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. 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." 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?
Blindfold the taster or just have her close her eyes. The tester then puts a
little bit of one food on the taster's tongue with a cotton swab. The taster
tries to identify which food she's tasting as well as whether it is salty,
bitter, sweet or sour. The tester records the taster's answers on the chart for
each food she tastes. 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.) Once the taster has tried each food
with her nose plugged, switch who tastes and who tests and go through it all
again. When you've both had a chance to taste, compare your results.
