Q1.
Draw arrows to indicate which side the pan balance will tilt? One is shown for you. a.Balance (a): soap bars on the left pan, a salt packet on the right.
Answer
Balance (a): soap bars on the left pan, a salt packet on the right.
This one is already done in the book. Let us check why.
Left pan: 6 × 200 g = 1200 g Right pan: 1 kg = 1000 g 1200 g > 1000 g
So the left pan (the soap bars) goes down and the right pan goes up.
The same balance after it settles.
Why it happens: A pan balance is a fair judge. The side carrying more grams always goes down, and the side carrying fewer grams rises.
Q2.
Draw arrows to indicate which side the pan balance will tilt? One is shown for you. b.Balance (b): chocolate bars on the left pan, a salt packet on the right.
Answer
Balance (b): chocolate bars on the left pan, a salt packet on the right.
Add up the left pan first.
Left pan: 8 × 100 g = 800 g Right pan: 1 kg = 1000 g 800 g < 1000 g
So the right pan (the 1 kg salt packet) goes down and the left pan goes up.
The same balance after it settles.
Why it happens: A pan balance is a fair judge. The side carrying more grams always goes down, and the side carrying fewer grams rises.
Q3.
Draw arrows to indicate which side the pan balance will tilt? One is shown for you. c.Balance (c): haldi packets on the left pan, a salt packet on the right.
Answer
Balance (c): haldi packets on the left pan, a salt packet on the right.
Add up the left pan first.
Left pan: 5 × 50 g = 250 g Right pan: 1 kg = 1000 g 250 g < 1000 g
So the right pan (the 1 kg salt packet) goes down and the left pan goes up.
The same balance after it settles.
Why it happens: A pan balance is a fair judge. The side carrying more grams always goes down, and the side carrying fewer grams rises.
Q4.
Draw arrows to indicate which side the pan balance will tilt? One is shown for you. d.Balance (d): tea leaves packets on the left pan, a salt packet on the right.
Answer
Balance (d): tea leaves packets on the left pan, a salt packet on the right.
Add up the left pan first.
Left pan: 3 × 250 g = 750 g Right pan: 1 kg = 1000 g 750 g < 1000 g
So the right pan (the 1 kg salt packet) goes down and the left pan goes up.
The same balance after it settles.
Why it happens: A pan balance is a fair judge. The side carrying more grams always goes down, and the side carrying fewer grams rises.

Big, heavy things go with kilograms. Small, light things go with grams.

Why it happens: A gram is very small — a paper clip is about 1 g. Counting a refrigerator in grams would need thousands of grams, which is hard to say. So for heavy things we use the bigger unit, the kilogram.
Tip: The book has already joined the baby to Kilograms with an arrow, to show you how to do the rest.
