Clean and Bright — Ask Yourself
1Did I brush my teeth today?Show solution
Given: A self-reflection question about personal hygiene.
Answer: Yes, I brushed my teeth today. Brushing teeth every morning (and before bed) removes food particles and germs, keeps our teeth strong, and prevents bad breath. It is an important daily hygiene habit.
2Did I take a shower?Show solution
Given: A self-reflection question about personal cleanliness.
Answer: Yes, I took a shower today. Taking a daily shower removes dirt, sweat, and germs from our body, keeps our skin healthy, and makes us feel fresh and comfortable throughout the day.
3Did I comb my hair?Show solution
Given: A self-reflection question about grooming.
Answer: Yes, I combed my hair today. Combing hair keeps it tidy, removes tangles, and helps keep the scalp clean. It is a simple but important part of our daily grooming routine.
4Did I wash my hands with soap?Show solution
Given: A self-reflection question about hand hygiene.
Answer: Yes, I washed my hands with soap. We should wash our hands with soap:
- After using the toilet
- Before and after eating food
- After coming home from outdoors
Washing hands with soap removes germs and helps prevent illness.
5Are my nails trimmed and clean?Show solution
Given: A self-reflection question about nail hygiene.
Answer: Yes, my nails are trimmed and clean. Keeping nails short and clean is important because dirt and germs can collect under long nails. These germs can enter our body when we touch food or our face, making us sick. We should trim our nails regularly and clean under them while washing hands.
Daily Routine Activity
1Write down the activities that you do every day, from the time you wake up till you go to sleep. Your list should include: Take a shower, Wash your hands with soap, Brush your teeth, Drink 6–8 glasses of water, Eat food, Sleep well for at least 8 hours total, Play outside.Show solution
Given: We need to write a daily routine that includes all the listed healthy habits.
Here is a sample daily routine:
- Wake up (6:30 am) — Use the toilet, brush teeth
- 7:00 am — Take a shower and get dressed
- 7:30 am — Have breakfast (eat food) and drink a glass of water
- 8:00 am — Wash hands with soap before leaving for school
- School hours — Drink water regularly (aim for 6–8 glasses throughout the day)
- Lunch break — Wash hands with soap before eating; eat food (lunch)
- After school (4:00 pm) — Wash hands after coming home from outdoors
- 4:30–5:30 pm — Play outside (at least 1 hour)
- 6:00 pm — Drink water; have an evening snack; wash hands before eating
- 8:00 pm — Have dinner (eat food); rinse mouth after eating
- 9:00 pm — Brush teeth before going to bed
- 9:30 pm — Sleep (sleep for at least 8 hours)
Note: Hands are washed with soap multiple times — after toilet, before meals, and after coming home from outdoors. Teeth are brushed twice — once after waking up and once before sleeping.
2Do you brush your teeth twice in the day — once after waking up and once before going to bed? Do you rinse your mouth every time after eating food? Do you wash your hands with soap after using the toilet and after coming home from outdoors? If your answer to any of these questions is 'No', think and discuss how you can make it a habit.Show solution
Given: Questions to check healthy hygiene habits and how to build them.
Answers and discussion:
- Brushing teeth twice a day:
- We should brush once after waking up and once before going to bed.
- To make it a habit: Keep the toothbrush and toothpaste in a visible place. Ask a family member to remind you. After a few days, it will become automatic.
- Rinsing mouth after eating:
- After every meal or snack, rinse your mouth with water. This removes food particles stuck between teeth and prevents tooth decay.
- To make it a habit: Always go to the washbasin after eating.
- Washing hands with soap:
- Always wash hands after using the toilet and after coming home from outdoors.
- To make it a habit: Keep soap near the washbasin. Make it a rule — 'No soap, no food.'
Things that might make it difficult: Not having easy access to water or soap, forgetting in a hurry, or not having a fixed routine. We can solve this by setting reminders and asking family members to help us follow these habits.
Activity 1 — Making a Home-Cleaner Using Orange and Lemon Peels
1Find out what home-cleaners are used in your home. You can also make your own eco-friendly cleaner using orange/lemon peels, cloves or bay leaves, and white vinegar. Describe the process.Show solution
Given: We need to find out about home-cleaners and learn to make an eco-friendly cleaner.
Home-cleaners commonly used at home:
- Soap or detergent (for floors and surfaces)
- Phenyl (for bathrooms)
- Dish-washing liquid (for utensils)
- Broom and mop (for sweeping and mopping)
How to make an eco-friendly home-cleaner:
Ingredients needed:
- Peels of 8–12 oranges or lemons (enough to fill a half-litre container)
- 10 whole cloves (laung) OR 2–3 bay leaves (tejpatta) — optional
- 2 cups of white vinegar (enough to cover the peels)
Steps:
- Collect the peels of oranges or lemons.
- Put the peels (and cloves or bay leaves if using) into a half-litre transparent container.
- Pour white vinegar over the peels until they are fully covered.
- Close the lid tightly.
- Keep the container in a sunny area for about two weeks.
- Shake the mixture occasionally during these two weeks.
- After two weeks, strain the liquid to remove the peels and spices.
- Your all-purpose eco-friendly cleaner is ready!
How to use it:
- Mix one cup of this liquid in one bucket of water.
- Use it to clean floors and bathrooms.
Why it is good: This cleaner is eco-friendly because it uses natural ingredients instead of harsh chemicals. It is safe for the environment and for our family.
Animals Like to Keep Themselves Clean Too!
1Have you ever seen monkeys sitting and grooming each other? Have you seen birds using their beaks to clean their feathers? Observe different ways in which animals and insects around you might be cleaning themselves.Show solution
Given: We need to observe and describe how animals keep themselves clean.
Animals also keep themselves clean in interesting ways:
- Monkeys: They sit together and groom each other. They use their fingers to pick out insects, dirt, and parasites from each other's fur. This keeps their bodies free from insects and also helps them bond with each other.
- Birds: Birds use their beaks to clean and arrange their feathers. This is called preening. They also take dust baths or water baths to keep their feathers clean.
- Cats: Cats lick their fur with their tongue to clean themselves. Their tongue has tiny rough bumps that act like a comb.
- Elephants: Elephants spray water or mud on their bodies using their trunks. The mud protects their skin from insects and the sun.
- Dogs: Dogs lick their paws and fur to clean themselves.
Conclusion: Just like humans, animals also have natural ways of keeping their bodies clean and healthy. Cleanliness is important for all living beings.
