Activity 1.1: Let us think and write (NCERT Solutions for Class 6 Science)
1. Write about a similar problem that you tried to solve.
Ans: You can write this answer this way.
One day, my toy car stopped moving. I had just played with it the day before, and it was working fine. I was curious to know what went wrong.
2. What steps did you take?
Ans: First, I checked if the car was switched on. It was. Then I guessed that maybe the batteries were dead. I opened the battery cover and saw that the batteries were old. I changed them with new ones, and the car started working again! If that didn’t work, I was going to check the wheels or the motor next.

1. If you have to ask “Why?” about something, what would you ask about?
Ans: I would ask, “Why do stars twinkle at night?” I look at the sky and see them shining and blinking, and I really want to know why they don’t just shine steadily like bulbs. It makes me curious every time I see them.
2. Try to write down how you would attempt to find an answer to your question.
Ans: First, I would ask my teacher or parents if they know why stars twinkle. Then, I would look in my science book to see if it explains it. If I still want to know more, I would search for the answer on a children’s science website or watch a video about stars. I would try to understand what makes the stars look like they are blinking.

Ans:
Type of Root: Radish is a taproot. It is a thick, main root that grows deep into the soil. The part we eat is the swollen taproot.
Type of Leaf Venation: Radish leaves have reticulate venation, which means the veins form a net-like pattern on the leaf surface.

| Color | Usually white or light-colored | Often brown, black, or mixed colors |
Reasons for differences:
- Mountain Goat – Adapted to cold climates with thick fur for warmth and strong hooves for climbing rocky terrain.
- Plain Goat – Lives in warmer areas, so has shorter fur and simpler hooves as it moves on flat ground.

6. As the population grows and people want more comfortable lives, forests are being cut down to meet various needs. How can this affect our surroundings? How do you think we can address this challenge?
Ans:
How cutting forests affects our surroundings:
- Animals lose their homes – Many animals live in forests. When trees are cut, they have nowhere to go.
- Soil gets washed away – Trees hold the soil together. Without trees, the soil gets washed away by rain.
- Less rain – Trees help in bringing rain. If we cut too many trees, it may not rain properly.
- Air becomes dirty – Trees clean the air and give us oxygen. Cutting them makes the air dirty and bad to breathe.
- Weather becomes too hot – Trees keep the weather cool. Without them, the Earth gets hotter.
What we can do:
- Plant more trees – For every tree cut, we should plant more trees.
- Use less paper – Save paper so fewer trees are cut.
- Tell others to save trees – We should tell our friends and family how important trees are.
- Don’t waste things – If we use only what we need, we won’t have to cut so many trees.
7. Analyse the flowchart. What can be examples of ‘A’ and ‘B’?

- How tall does the Gudhal plant grow?
- Is the stem of the Gudhal plant hard or soft?
- Have you seen where Gudhal is usually planted—garden, pot, or forest?
9. Based on the information in the table, find out examples of these plants for each group.
(a) What other similarities do plants of group A have?
(b) What other similarities do plants of group B have?
Ans: Examples of group A will be – Bean, Mango, Neem. and examples of group B will be – Wheat, Rice, Onion.
Similarities of group A plants:
- Leaves show reticulate venation.
- Flowers mostly have 4 or 5 petals.
- Seed splits into two parts.
