Project Work

ADiscuss why is it important to take water in a bucket for bathing instead of shower or running tap water.

Given: A discussion on water conservation.

Concept: Water is a precious natural resource and should not be wasted.

Working:

A running shower or tap uses a continuous flow of water, much of which goes to waste.
A bucket holds a fixed, limited amount of water, so we use only what we need.

Answer: It is important to use a bucket for bathing because:

A bucket uses a fixed, limited amount of water.
A running tap or shower wastes a lot of water continuously.
We must save water as it is very precious.
Using a bucket helps us be careful and responsible about how much water we use.

Compare: the container that needs fewer refills to fill the bottle holds more water per fill.

Answer (Sample):

It took 4 glasses to fill the bottle.
It took 2 bowls to fill the bottle.
Therefore, the bowl holds more water than the glass.
Among all containers, the biggest bottle holds the most water.

(Actual answers will vary depending on the sizes of containers used.)
