1. Find a few friends who are willing
to be take part in your experiment.
2. Collect and prepare all the different
foods that you are going to use in
your test. Cut your straws in half
to give you more.
3. Place the blind folds on your
friends. Do not let your friends see
the foods before the testing begins.
Keep them in suspense and see if they
can guess the food you have placed
on their tongue.
4. Place one item at a time on each
persons tongue and see who can guess
the items that have been used. Use
the straws as dropper and not for
sipping by placing the straw in the
liquid and positioning your thumb
over the top of the straw to trap
a drop or two of the liquid.
5. Ask your volunteers to pinch their
nose as you place a food item on their
tongue and ask if they can guess what
item of food it is.

3. Did any of the above
foods taste better or worse with the
blind fold on?
4. Did you notice that your
tongue discovered the different textures

pinched your nose for the taste test?
Did you loose your sense of taste?
6. Did you notice that
your tongue sensed sweet, salty, bitter
and sour foods on different parts
of your tongue?
