CLASS-V TWAU CHAPTER-1

1. Competency-Based Assessment Questions (with answers)

Q1. Observation Competency
Activity: Put ice cubes in a steel glass. After some time, water droplets form outside the glass.

👉 Why did water droplets form?
Answer: Water vapour in the air cooled on touching the cold glass and changed into water droplets (condensation).

Q2. Identification Competency
Match the following:
(i) Ocean water — (a) Freshwater
(ii) Rainwater — (b) Not fit for drinking
(iii) Snow — (c) Solid form of water
(iv) Steam — (d) Vapour form of water

Answer:
(i) Ocean water → (b) Not fit for drinking
(ii) Rainwater → (a) Freshwater
(iii) Snow → (c) Solid form of water
(iv) Steam → (d) Vapour form of water

Q3. Classification Competency
Classify into Surface Water and Groundwater:
River, Lake, Tube well, Pond, Borewell
Answer:

• Surface Water: River, Lake, Pond

• Groundwater: Tube well, Borewell

• 
  
  

  
  

Q4. Discovery of Facts
Why is freshwater so important for life?
Answer: Because it is needed for drinking, farming, daily activities, and supports plants, animals, and humans.

Answer: Aquatic life will die, water will become unsafe for drinking, farmers won’t get clean water for crops, and communities will face water scarcity.

Q3. Compare rainwater in a forest and a city. Where will more water seep underground, and why?
Answer: In a forest, more water will seep underground because of open soil and trees. In a city, cemented roads block water absorption.

(b) What can other villages and cities learn from Hivare Bazar?

Answer:
(a) Water-positive means a place that has more water available than it consumes, because of good conservation practices.
(b) Other places can learn to store rainwater, reduce wastage, recharge groundwater, and work together as a community to solve water problems.
