Worksheet: My Sense Organs

Subject: EVS (Environmental Studies)
Grade: I

---

Q1. Write True or False

We need to evaluate each statement based on our knowledge of sense organs.

1. We taste the mango with our tongue.
✔ True – The tongue is responsible for tasting food.

2. I see the colourful kites with my ears.
✘ False – We see with our eyes, not ears. Ears are for hearing.

3. We have five sense organs.
✔ True – The five sense organs are: eyes (sight), ears (hearing), nose (smell), tongue (taste), and skin (touch).

4. I hear the sound of doorbell with my nose.
✘ False – We hear sounds with our ears, not the nose.

5. I feel with my skin.
✔ True – The skin helps us feel touch, temperature, pain, etc.

Q2. Circle the odd one out

We need to identify which image in each row does not belong with the others.

#### 1.
- First image: Gift boxes with balloons → associated with celebrations (like birthdays).
- Second image: Santa Claus → associated with Christmas.
- Third image: Food cooking in a pot → associated with cooking/eating.

🔍 Analysis:
- Gift boxes and Santa Claus are both related to festivals/holidays (birthday & Christmas).
- Cooking food is a daily activity, not specifically tied to a festival.

✔ Odd one out: Cooking food (third image)

> So, circle the third image (the pot with food).

#### 2.
- First image: Penguin → animal, lives in cold regions.
- Second image: Moon and stars → night sky.
- Third image: Drum → musical instrument.

🔍 Analysis:
- Penguin and drum are objects/creatures we can see during the day or night.
- Moon and stars are nighttime elements.

But let’s think differently:
- Penguin is an animal.
- Drum is a musical instrument.
- Moon and stars are natural celestial objects.

Wait — actually, notice:
- Penguin and drum are things that make noise (penguin might squawk, drum makes sound).
- Moon and stars are silent.

Alternatively, consider day vs night:
- Penguin: seen during day
- Drum: used anytime
- Moon and stars: only visible at night

But perhaps better:
Look at categories:

- Penguin → Animal
- Moon and stars → Sky/Nature
- Drum → Musical instrument

Wait — here’s a better idea:

Look at what they represent:
- Penguin → Animal
- Moon and stars → Night time
- Drum → Sound/Music

But none are clearly same category.

Alternative approach:
Check if two are animals?

Only penguin is an animal.

Drum is object, moon/stars are celestial.

Wait — what if it's about sound?

- Penguin: makes sound (squawking)
- Drum: makes sound (beaten)
- Moon and stars: silent

So, moon and stars do not make sound.

✔ Odd one out: Moon and stars (second image)

> So, circle the second image (moon and stars)

But wait — maybe it's about living things?

- Penguin → living
- Moon and stars → non-living
- Drum → non-living

Then both moon/stars and drum are non-living, but penguin is living.

So penguin is odd one out?

But then why would drum be included?

Wait — let’s re-express:

Actually, this is ambiguous unless we know the theme.

But look again:

- Penguin: Animal
- Moon and stars: Night scene
- Drum: Instrument

Wait — another idea: Can you hear them?

- Penguin: yes (makes sound)
- Drum: yes (makes sound)
- Moon and stars: no sound

So moon and stars don’t make sound → odd one out

✔ So, circle the second image (moon and stars)

#### 3.
- First image: Mobile phone ringing → technology/sound
- Second image: Birthday cake → celebration
- Third image: Mangoes → fruit

🔍 Analysis:
- Mobile phone: electronic device
- Birthday cake: food item (celebration)
- Mangoes: food item (fruit)

Now, birthday cake and mangoes are food items.
Mobile phone is not food.

So, mobile phone is the odd one out.

✔ Odd one out: Mobile phone (first image)

> So, circle the first image (mobile phone)

---

✔ Final Answers:

#### Q1. True or False:
1. True
2. False
3. True
4. False
5. True

#### Q2. Circle the odd one out:
1. Circle the third image (cooking food)
2. Circle the second image (moon and stars)
3. Circle the first image (mobile phone)

📝 Summary Explanation:

- Sense organs help us experience the world: sight (eyes), hearing (ears), smell (nose), taste (tongue), touch (skin).
- In Q1, we use logic to check if statements match correct sense organ functions.
- In Q2, we group images by common themes and find the one that doesn't fit.
