Step by Step
1. Decide on 8 to 10 vegetables from the picture cards provided (You are strongly encouraged to select the 4 vegetables that are marked with an *).
2. Wash and prepare the vegetables that you have selected for tasting.
3. The vegetables on the picture cards with orange labels have to be steamed for 15 minutes before consuming.

5. Together with your adult assistant, cut the vegetables into bite-sized pieces.
6. Put on the blindfold and get your adult assistant to feed you one piece of vegetable at a time.
7. Compare your findings with the guess on the Blind Tasting Card.
When food rubs against the taste buds, it causes the sensation we call taste. The receptor cell then sends electrical impulses to the brain. The brain interprets the sensations as taste.
We can taste sweet, salty, sour and bitter with our tongue.
Our sense of taste alerts us not to eat food that have gone bad so that we will not become ill.
Imagine eating food that has no taste. People with taste disorders or even smell disorders have distorted taste or no sense of taste at all.
What you need
- Cotton Swabs*

Step by Step
1. Put a little bit of lemon juice, honey, salt, and baking cocoa into each of the small cups provided.
2. Mix the salt and baking cocoa together with some water.
3. Make some predictions. Where on your tongue do you think each flavour will taste the strongest? Write down your predictions on the Tongue Map.
4. Have your adult assistant dip a cotton swab into one of the liquids and dab it on area A of your tongue.
5. Taste the liquid, then take a sip of water to clear your tongue of the taste.
6. Have your adult assistant dip a new cotton swab in the same liquid and dab it on area B of your tongue. Taste the liquid again and sip some water. Repeat the same procedure with area C and D of your tongue.
7. Which part of your tongue tasted the liquid the strongest? Record your answer on the Tongue Map.
Hanig's diagram indicates that sensitivity to Sweet tastes was highest on the tip of the tongue. Bitter tastes was highest at the base, while Sour tastes was highest on the edges of your tongue. He also found that Salty tastes was equally as sensitive on all areas of the tongue's perimeter.
Are the results of your taste test the same as Hanig's diagram?
