Activity 2 — The Journey of a Grain

1Put a tick (✓) on the elements that assist a grain in its journey.

| Soil | Stone | Air | Wood | Water | Tiger |
| Farmer | Earthworm | Hills | Fire | Insect | Bat |
Show solution
Elements that assist a grain in its journey are ticked below:

| Soil ✓ | Stone | Air ✓ | Wood | Water ✓ | Tiger |
| Farmer ✓ | Earthworm ✓ | Hills | Fire | Insect | Bat |

Explanation:
- Soil provides nutrients and a base for the seed to grow.
- Air (sunlight and wind) helps in pollination and photosynthesis.
- Water is essential for germination and growth of the plant.
- Farmer sows, tends, and harvests the grain.
- Earthworm loosens the soil and makes it fertile.

Stone, Wood, Tiger, Hills, Fire, Insect, and Bat do not directly assist a grain in its journey from seed to plate.

Write — Role of Farmers and Missing Elements

1What is the role of farmers in this process?Show solution
Role of Farmers in the Journey of a Grain:

Farmers play the most important and central role in the journey of a grain. Their roles include:
1. Preparing the soil — They plough and till the land to make it ready for sowing.
2. Sowing seeds — They plant the seeds in the prepared soil at the right time and season.
3. Watering the crops — They irrigate the fields regularly so that the plants get enough water.
4. Applying fertilisers and manure — They enrich the soil with nutrients to help the crops grow well.
5. Protecting the crops — They protect the crops from pests, insects, and diseases.
6. Harvesting — They cut and collect the ripened grain from the fields.
7. Threshing and storing — They separate the grain from the stalks and store it safely.

Without the hard work of farmers, no grain would reach our plate.
2List out the missing elements in the table above (elements that also assist a grain in its journey but were not ticked).Show solution
Missing elements that also assist a grain in its journey (not already ticked in the table) include:

1. Sunlight — Provides energy for photosynthesis, helping the plant make food and grow.
2. Cattle / Bullocks — Used by farmers to plough the fields.
3. Insects (Bees) — Help in pollination of flowering plants.
4. Shopkeeper / Trader — Buys grain from farmers and sells it to consumers.
5. Cook / Family members — Clean, cook, and prepare the grain into food that reaches our plate.

*(Note: From the given table options, Air and Water were missing ticks and should be ticked. Among the listed options, Insect can assist through pollination and should be considered.)*

Write — Roles of Different Elements in the Journey of a Grain

aSoil: What is the role of soil in the journey of a grain?Show solution
Role of Soil:
Soil provides the base and nutrients needed for a seed to germinate and grow into a plant. It holds the roots firmly, supplies minerals and organic matter, and retains moisture that the plant needs to survive and produce grain.
bWater: What is the role of water in the journey of a grain?Show solution
Role of Water:
Water is essential for the germination of seeds. It helps the plant absorb nutrients from the soil, supports photosynthesis, and keeps the plant healthy and alive. Without water, the seed cannot sprout and the plant cannot grow.
cFarmer: What is the role of the farmer in the journey of a grain?Show solution
Role of the Farmer:
The farmer prepares the soil, sows the seeds, waters and fertilises the crops, protects them from pests, harvests the ripened grain, and sends it to the market. The farmer's hard work and dedication are the foundation of the entire process.
dCattle: What is the role of cattle in the journey of a grain?Show solution
Role of Cattle:
Cattle (like bullocks and cows) help farmers plough and till the fields, making the soil loose and ready for sowing. Their dung is used as natural manure (compost) to enrich the soil with nutrients, which helps the crops grow better.
eShopkeeper: What is the role of the shopkeeper in the journey of a grain?Show solution
Role of the Shopkeeper:
The shopkeeper buys grain from farmers or wholesalers and sells it to families and consumers. The shopkeeper acts as a link between the producer (farmer) and the consumer (family), making the grain available in local markets and shops.
fFamily members: What is the role of family members in the journey of a grain?Show solution
Role of Family Members:
Family members, especially the cook at home, clean, wash, and cook the grain to prepare nutritious meals. They decide what to cook, serve the food, and ensure that nothing is wasted. They are the final link in the journey that brings the grain to our plate as a delicious meal.
gAny other: Name any other element and describe its role in the journey of a grain.Show solution
Any Other Element — Sunlight:
Sunlight provides the energy needed for photosynthesis. The green leaves of the plant use sunlight, water, and carbon dioxide to make food for the plant. Without sunlight, the plant cannot grow and produce grain.

Earthworm:
Earthworms loosen and aerate the soil by burrowing through it. This makes the soil soft and fertile, allowing roots to grow easily and water to seep in. They are called 'friends of the farmer' for this reason.

Activity 3 — Thank You Everyone!

1Whom would you like to thank for the food you eat? Please write your answers.Show solution
I would like to thank the following people and elements for the food I eat:

1. Farmers — for their tireless hard work in growing the crops in all kinds of weather.
2. Earthworms and soil — for keeping the soil fertile and healthy.
3. Sun and Rain — for providing sunlight and water that help crops grow.
4. Cattle — for helping plough the fields and providing manure.
5. Truck drivers and transporters — for carrying the grain from farms to markets.
6. Shopkeepers and vendors — for making food available near our homes.
7. My mother / family members — for cooking delicious and nutritious meals with love and care.
8. Nature — for providing all the resources needed to grow food.

I am truly grateful to everyone involved in this long and wonderful journey that brings food to my plate.

Discuss — Mindful Eating

1What role does your tongue play in this process of mindful eating?Show solution
Role of the Tongue:
The tongue plays a very important role in mindful eating:
- It helps us feel the texture and surface of the food (whether it is smooth, rough, hard, or soft).
- It helps us taste the flavour of the food — whether it is sweet, salty, sour, bitter, or spicy.
- It moves the food around inside the mouth so that the teeth can chew it properly.
- It helps us swallow the food by pushing it towards the throat.

Thus, the tongue is our main organ for tasting and feeling food.
2What do your teeth do to the food?Show solution
Role of Teeth:
Teeth help in the process of chewing (also called mastication):
- The front teeth (incisors) cut and bite the food into smaller pieces.
- The canine teeth help in tearing the food.
- The back teeth (molars and premolars) grind and crush the food into a fine paste.

By breaking the food into tiny pieces, teeth make it easier for the stomach to digest the food. Chewing well is the first and most important step of digestion.
3What happens to the food inside your mouth during this process of mindful eating?Show solution
What Happens to Food Inside the Mouth:

When we eat mindfully and chew slowly, the following things happen inside the mouth:
1. The teeth cut, tear, and grind the food into smaller and smaller pieces.
2. Saliva (produced by salivary glands) mixes with the food. Saliva contains enzymes that begin the process of digestion — it starts breaking down starchy foods.
3. The tongue moves the food around, mixes it with saliva, and helps form a soft, moist ball called a bolus.
4. The food becomes soft and easy to swallow.
5. We experience the taste, flavour, and texture of the food fully.

Thus, the mouth is where digestion begins, and mindful eating helps us enjoy and digest food better.

Write — Valuing Food

1What will you do if someone offers you food more than you need?Show solution
Answer:
If someone offers me food more than I need, I will politely say, 'No, thank you. I have had enough.' I will take only as much food as I can eat so that nothing is wasted. I know that every grain of food is precious and is the result of a farmer's hard work, so I will never take more than I need.
2What will you do if you do not like a food item on your plate?Show solution
Answer:
If I do not like a food item on my plate, I will still try to eat a little of it, because it may be nutritious and good for my health. I will not waste it. If I truly cannot eat it, I will politely tell the person serving me beforehand so that they do not put it on my plate. I will remember that wasting food is disrespectful to the farmer and everyone who worked hard to bring it to my plate.

On a day when I play a lot, I feel:
- Happy and joyful — Playing with friends makes me feel cheerful and excited.
- Energetic — My body feels active and strong during play.
- Tired but satisfied — After playing, I feel physically tired, but it is a good kind of tiredness.
- Hungry — I feel very hungry after playing, and food tastes even better.
- Sleepy at night — I sleep deeply and peacefully after a day of lots of play.
- Fresh the next morning — After a good sleep, I wake up feeling refreshed and ready for a new day.

Overall, playing a lot makes me feel healthy, happy, and full of life.

Find Out — Games in Pictures

1Can you name the games depicted in the pictures? (img_9, img_10, img_11, img_12)Show solution

1. Kabaddi — A traditional Indian team sport.
2. Kho-Kho — A traditional Indian tag sport.
3. Badminton — Played with a racket and shuttlecock.
4. Cricket — Played with a bat and ball.

Students should look at their textbook pictures and write the correct names of the games shown.

Discuss — Sleep Well Too!

1Think about a day when you exercised or played a lot. What do you think would happen if you did not sleep well after that?Show solution
What Would Happen Without Proper Sleep After Exercise:

If I did not sleep well after a day of lots of exercise and play:
1. My body would not get the rest it needs to recover from tiredness.
2. I would feel very tired, weak, and exhausted the next day.
3. I would find it difficult to concentrate in class or while studying.
4. I would feel irritable and moody — easily upset or angry.
5. My muscles would ache more because they did not get time to repair during sleep.
6. I would feel sleepy throughout the day and unable to enjoy any activity.
7. My immune system (ability to fight illness) would become weaker.

This shows that sleep is just as important as exercise and eating well for a healthy body and mind.
2Discuss: Why do you think our body needs rest?Show solution
Why Our Body Needs Rest:

Our body needs rest because:
1. Repair and recovery — During sleep, our body repairs worn-out muscles and tissues that get tired during the day.
2. Energy restoration — Rest restores the energy we use up during physical and mental activities.
3. Brain function — Sleep helps the brain process and store information we have learnt during the day, which improves memory and concentration.
4. Growth — Growth hormones are released during sleep, which help children grow taller and stronger.
5. Immune system — Adequate rest strengthens our immune system, helping us fight diseases.
6. Mood and emotions — A well-rested body and mind keep us happy, calm, and positive.

Therefore, getting 8–10 hours of sleep every night is essential for children.
3Discuss: Do you think it is important to rest after a busy day of exercise and play? Why?Show solution
Importance of Rest After Exercise and Play:

Yes, it is very important to rest after a busy day of exercise and play because:
1. Muscle recovery — During exercise, our muscles work very hard and develop tiny tears. Rest allows these muscles to heal and become stronger.
2. Prevents injury — Without rest, tired muscles are more likely to get injured.
3. Restores energy — Rest replenishes the energy (glycogen) used up during physical activity.
4. Mental relaxation — Rest calms the mind and reduces stress after an active day.
5. Better performance — A well-rested body performs better in sports and studies the next day.

Just as a machine needs to be switched off to avoid overheating, our body needs rest to function well.

Write — Feeling Safe

1What would you do if someone's touch made you feel uncomfortable?Show solution
What I Would Do If Someone's Touch Made Me Feel Uncomfortable:

If someone's touch made me feel uncomfortable, I would:
1. Say 'No' firmly and loudly — I would immediately tell the person to stop and say 'No' clearly.
2. Move away from that person as quickly as possible.
3. Tell a trusted adult — I would immediately tell my parents, teacher, or another trusted adult about what happened.
4. Not feel guilty — I would remember that it is never my fault if someone touches me in a way that makes me uncomfortable.
5. Not keep it a secret — I would speak up, because staying silent can allow the unsafe behaviour to continue.

Remember: My body belongs to me, and I have the right to feel safe at all times.
2If you face an unsafe situation, who would you tell?Show solution
People I Would Tell If I Face an Unsafe Situation:

If I face an unsafe situation, I would immediately tell:
1. My parents (mother or father) — They are my first and most trusted protectors.
2. My teacher — At school, my teacher is a trusted adult who can help me.
3. My grandparents — They are caring and trustworthy family members.
4. An elder sibling — An older brother or sister can also help and guide me.
5. School counsellor — If available, the school counsellor is trained to help in such situations.

I will never stay silent if I feel unsafe. Speaking up is the bravest and most important thing I can do.
3List two situations where you would firmly say 'No'.Show solution
Two Situations Where I Would Firmly Say 'No':

1. If a stranger or known person tries to touch my private body parts — I would firmly say 'No', move away, and immediately tell a trusted adult.

2. If someone asks me to go with them to a lonely or unknown place without my parents' permission — I would firmly say 'No' and inform my parents or teacher.

*(Additional examples: If someone tries to bully me or force me to do something that makes me feel scared or uncomfortable, I would say 'No' and seek help.)*

Let Us Reflect

1If the following are missing, what would happen to a food grain?

Elements: Soil, Water, Sunlight
Animals: Cattle, Earthworm
People: Farmer, Shopkeeper, Cook
Show solution
What Would Happen If Each Element Were Missing:

Elements:
- Soil: Without soil, the seed would have no place to germinate and grow. There would be no nutrients or support for the roots, and the plant could not survive. No grain would be produced.
- Water: Without water, the seed would not germinate. The plant would dry up and die. Crops cannot grow without regular watering or rainfall.
- Sunlight: Without sunlight, the plant cannot perform photosynthesis and cannot make its own food. The plant would become weak, pale, and eventually die. No grain would form.

Animals:
- Cattle: Without cattle, farmers would find it very difficult to plough the fields. The soil would not be tilled properly, making it hard to sow seeds. Also, natural manure from cattle would be unavailable, reducing soil fertility.
- Earthworm: Without earthworms, the soil would become hard and compact. It would not be aerated or enriched with nutrients. The roots of plants would struggle to grow, and the soil would become less fertile over time.

People:
- Farmer: Without the farmer, no one would sow the seeds, water the crops, protect them from pests, or harvest the grain. The entire process of food production would come to a halt.
- Shopkeeper: Without the shopkeeper, the harvested grain would not reach consumers. There would be no link between the farmer and the family, and people in cities and towns would not get food.
- Cook: Without the cook, the raw grain would not be transformed into edible food. Even if grain reached our home, it would not become the nutritious meal that reaches our plate.
2Design your own favourite plate of balanced diet with the food items you like. (Remember we should not waste food.)

| Breakfast plate | Lunch plate | Dinner plate |
Show solution
My Favourite Balanced Diet Plates:

*(This is a sample answer. Students should fill in their own favourite healthy food items.)*

| Breakfast Plate | Lunch Plate | Dinner Plate |
|---|---|---|
| Idli with sambar | Chapati (2) | Dal and rice |
| A glass of milk | Dal (lentil curry) | Sabzi (vegetable curry) |
| One banana | Rice | Curd |
| Boiled egg | Mixed vegetable sabzi | One fruit (apple) |
| | Salad (cucumber, tomato) | A glass of warm milk |

Note: A balanced diet includes carbohydrates (rice, chapati), proteins (dal, egg, milk), vitamins and minerals (fruits, vegetables), and fats in small amounts. I will take only as much as I can eat so that I do not waste any food.
3Which activities did you enjoy during your 'mindful eating'?Show solution
Activities I Enjoyed During Mindful Eating:

During the mindful eating exercise, I enjoyed:
1. Feeling the texture of the peanut with my fingers and tongue — it was a new and interesting experience.
2. Discovering the taste slowly — I noticed the salty and nutty flavour much more clearly than when I eat quickly.
3. Listening to the sound of the crunch when I bit into the peanut.
4. Smelling the aroma of the food before putting it in my mouth.
5. Chewing slowly and feeling how the texture changed from crunchy to soft.

Mindful eating helped me appreciate my food much more and made me realise how much I usually miss when I eat in a hurry.
4How can you keep your body strong? Write down the names of the exercises and games you would practice.
