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
so you have more straws (try not to be too wasteful - be kind to our environment).
3. Place the blind folds on your
friends. Do not let your friends see
the food samples 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 of food or liquid it is.
Here are a few questions
you could ask your friends when you
have finished your experiment:
1. How well did your sense
of smell kick in when your sense of
sight and sense of touch were not
2. Were you a bid afraid
of what food or liquid might be placed on your
3. Did any of the above
foods or liquids taste better or worse with the
blind fold on?
4. Did you notice that your
tongue discovered the different textures
5. What happened when you
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 and liquids on different parts
of your tongue?
Taste - Our tongue can detect only
four basic flavors.
1. Sweet - detected at the
tip of your tongue
2. Salty - detected at the front
sides of your tongue
3. Sour - detected along the
rear sides of your tongue
4. Bitter - detected across
the back of your tongue
