Collect a few food items having different kinds of tastes. Play a game with your friends as Jhumpa and Jhoolan did. Tell your friend to taste the food and ask -  

One at a time put some things to eat in other parts of your mouth - under the tongue, on the lips, on the roof of the mouth. Did you get any taste there?

Use a clean cloth to wipe the front part of your tongue so that it is dry. Put some sugar or jaggery there. Could you taste anything? Why did this happen?

Stand in front of a mirror and look closely at your tongue. How does the surface look? Can you see any tiny bumps on the surface?

If someone asks you to describe the taste of amla or cucumber, you might find it difficult to explain.

How would you describe the taste of these – tomato, onion, saunf, garlic.

Think of words that you know or make up your own words to describe the taste.

When Jhumpa tasted some of the things, she said “Sssee, sssee, sssee…” 

What do you think she may have eaten?

Why don’t you make sounds that describe some tastes?

From your expressions and sounds ask your friends to guess what you might have eaten.

Has anyone at home told you to eat slowly and to chew well so that the food digests properly? Why do you think they say this?

How do you feel when you are very hungry? How would you describe it? For example, sometimes we jokingly say, “I am so hungry I could eat an elephant!”

How do you come to know that you are hungry?

Think what would happen if you do not eat anything for two days?

Would you be able to manage without drinking water for two days? Where do you think the water that we drink goes?

Do you remember that in Class IV you made a solution of sugar and salt? Nitu’s father also made this and gave her. Why do you think this is given to someone who has vomiting and lose motions?

Have you heard the word ‘glucose’, or seen it written anywhere? Where?

Have you ever tasted glucose? How does it taste? Tell your friends.

Have you or anyone in your family been given a glucose drip? When and why? Tell the class about it.

Nitu’s teacher used to tell the girls to have glucose while playing hockey. Why do you think she did this?

Look at Nitu’s picture and describe what is happening. How is the glucose drip being given?
