How much can you drink

Chintu does not take the challenge because the glasses are bigger, so he will have to drink more juice. It will be difficult for him.

Yes, I can take the challenge if I use smaller glasses because I will have to drink less juice.

Let us Do

Take a small bowl, glass, and bottle. First guess how many bowls fill the glass and how many glasses fill the bottle. Then pour water to check your guess.

1.
a. The glass holds the least water.
b. The bottle holds the most water.

2. Bucket, tank, drum.

(Activity – Vessels)

Let us Do

1. Answers may vary depending on the size of the ladle, bowl, and jug.
2. Answers may vary depending on the size of vessels used.
3. Ladle
4. Ladle, because it helps to pour equal amounts into each glass.
5. Answers may vary based on the size of vessels used.
6. Answers may vary based on the size of vessels used.
7. Yes, we can use a ladle, bowl or glass to measure a jug by repeatedly filling and counting how many times it fills the jug.

Let us Discuss

a. The glass holds less than 1 litre.
b. The bowl holds more than 1 litre.
c. Jug holds exactly 1 litre.

Let us Think

a. The mug holds half litre of water.
b. The glass holds Quarter litre of water.

Let us Explore

Use a 1 litre bottle to compare and check capacities of the bucket, mug, and glass by filling and observing.

a. Bucket → more than 1 litre
b. Mug → more than half litre
c. Glass → less than quarter litre

Heavy or Light

Hold objects in both hands and observe which side goes down. The heavier object goes down.

The lunch box is heavier than the pencil box.
The school bag is heavier than the lunch bag.
The watermelon is heavier than the apple.
A basketball is heavier than a balloon.

Let us Do

Use coins or erasers to balance objects on a pan balance and record them.

1.
Pencil – 2 coins
Ping pong ball – 1 coin
Spoon – 3 coins

2. Fill a matchbox with sand and use it as a unit to weigh objects. First guess, then verify.

3. Order (lightest to heaviest): 4 marbles < spoon < pencil box

Let us Do

weight hunt

1. Compare school bags in groups and observe differences in weight.
2. Count the number of books in each bag. The bag with more books is heavier.
3. By making the number of books equal in both bags, their weights can be balanced.

How much is 1 Kilogram

4. Examples of 1 kilogram objects are rice packet, sugar packet, and flour packet.

5. Answers may vary.

Let us Explore

Half kg objects:
Sugar packet (½ kg)
Dal packet (½ kg)

Quarter kg objects:
Butter packet (¼ kg)
Small fruit pack (¼ kg)

Tricky Balls

Identify objects at home that are about half kg and quarter kg. Compare with a 1 kg packet and verify.

1.
a. Only 1 time
b. Weigh any two balls.
- If equal → third ball is heavier
- If not equal → heavier side has the heavy ball

2.
Weigh Red vs Orange
- If equal → Green is different
- If not equal → compare heavier one with green
- From results, identify heaviest and lightest.
