What these solutions cover

All 27 questions in Water — The Essence of Life are solved in the PDF. Here's what's inside, exercise by exercise:

Discuss — Ocean Water

  1. Do you think we can drink the water present in the oceans?
  2. What can ocean water be used for?

Activity 1 — Freshwater Sources (Identify from Images)

  1. Where can we find freshwater? Identify the different freshwater sources from the images given and write their names.

Activity 2 — Water Has Different Forms

  2. What happens to the ice cubes after they are left in the glass for some time?
  3. If we heat water, what will happen to it?
  4. In the above activity, what forms of water do you see?

Activity 3 — Water Cycle (Transparent Bag)

  1. In the transparent bag activity (with coloured water placed in sunlight), what do you observe? Water heats up — how does it happen?

Activity 4 — Groundwater (Soil Experiment)

  1. When water is slowly poured into a glass half-filled with soil, what do you observe?

Activity 5 — Tick the Image for Groundwater Recharge

  1. Tick the image that will help in groundwater recharge. (Images shown: concrete road, green lawn/open area, paved area.)

Activity 6 — Mustard Seeds (How Rivers Flow)

  1. What did you observe about the mustard seeds when poured on the highest point of the crumpled newspaper slope?
  2. Are the mustard seeds moving in a straight line, or do they spread out in different directions?
  3. Are the mustard seeds collecting in some areas? Do they gather like water gathers in lakes, rivers and so on?

Discuss — Rivers Towards Arabian Sea and Bay of Bengal

  1. Based on the mustard seeds activity, discuss how some rivers flow towards the Arabian Sea while some flow towards the Bay of Bengal.

Activity 7 — Follow the Flow! (Rivers Map Table)

  1. Observe the map of rivers in India and fill in the table: Which rivers move towards the Bay of Bengal, and which towards the Arabian Sea?

Complete the Table — Animals on Land vs Animals in Water

  1. Complete the following table by discussing with peers about the characteristics of animals on land and animals in water.

Activity 8 — Visit a Water Body (Observation Table)

  1. Visit a local water body (pond, lake, or aquarium) with your teacher or parents. Observe the birds and animals and complete the observation table (name, mouth/beak, movement, legs/feet/fins, rough diagram).
  2. Draw the plants that you saw during the visit and label them with their local name.

Worked examples

3 questions from Water — The Essence of Life, solved step by step.

Discuss — Ocean Water

Do you think we can drink the water present in the oceans?

No, we cannot drink ocean water. Ocean water is salty (saline), and drinking it is harmful to humans.

All living beings need freshwater for drinking. Only a very small amount of Earth's water is freshwater, which comes from rivers, lakes, ponds, and groundwater.

Answer: No. Ocean water is salty and not fit for drinking. We need freshwater for drinking.

Activity 1 — Freshwater Sources (Identify from Images)

Where can we find freshwater? Identify the different freshwater sources from the images given and write their names.

The images around 'Sources of Water' show these freshwater sources:

1. Lake — a calm water body with green banks.

2. Glacier / ice cap — frozen freshwater (iceberg and snow-covered mountains).

3. Snow-capped mountains — snow is frozen freshwater that melts to feed rivers.

4. River — a river winding through green land.

5. Groundwater — drawn from the ground using a well / handpump.

6. Rain — rain clouds bring freshwater to Earth.

(One image shows the sea/ocean too, but that water is salty, not freshwater.)

Answer: The images show freshwater sources: a lake, a glacier/ice cap, snow-capped mountains, a river, groundwater (handpump), and rain.

Activity 2 — Water Has Different Forms

A steel glass has ice cubes in it. Small water droplets form on the outside of the glass. Where do these water droplets come from?

The air around us contains water vapour (invisible moisture).

The outside of the cold glass is much cooler than the surrounding air.

When the moist air touches the cold glass, it cools down and turns into tiny liquid water droplets.

This process is called condensation.

Answer: The droplets come from the water vapour in the air around the glass. When warm moist air touches the cold glass, it cools and condenses into water droplets.
