CBSE Class 4 Maths How Heavy How Light Worksheet Set 02

I. Tick the one which has more weight.

Question 1(a). Elephant / Dog
Answer: Elephant
In simple words: An elephant is a massive wild animal that weighs several thousand kilograms, whereas a dog is a small domestic animal weighing only a few kilograms. Therefore, the elephant has much more weight.

Exam Tip: Compare the physical sizes of the given objects or animals in real life to quickly determine which one is heavier.

Question 1(b). Book / Pencil
Answer: Book
In simple words: A book is made of many pages and a thick cover, making it heavier than a thin wooden or plastic pencil.

Exam Tip: Objects with greater volume and more material generally weigh more than smaller, slender objects.

Question 1(c). Table / School Bag
Answer: Table
In simple words: A table is large and usually made of solid wood or metal, which is much heavier than a school bag filled with books and notebooks.

Exam Tip: Furniture items like tables and chairs are always heavier than standard student school bags.

Question 1(d). Scale / Chair
Answer: Chair
In simple words: A chair is designed to support the full weight of a human body and is much heavier than a light plastic or metal measuring scale.

Exam Tip: Always think about daily utility items and their built materials to judge weight differences correctly.

II. Which pan will go down show by drawing an arrow.

Question 2(a). Loaf of bread vs Book
Answer: The pan containing the book will go down.
In simple words: A book is denser and heavier than a light, fluffy loaf of bread. On a physical balance scale, the heavier side always goes down.

Question 2(b). Pan weights: 250gm and 310gm vs 125gm and 360gm
Answer:
Total weight on the left pan = \(250\text{ gm} + 310\text{ gm} = 560\text{ gm}\)
Total weight on the right pan = \(125\text{ gm} + 360\text{ gm} = 485\text{ gm}\)
Since \(560\text{ gm} > 485\text{ gm}\), the left pan will go down.
In simple words: Add the two weights on each side together. The side with the larger total sum is heavier and will tilt downward.

Exam Tip: Always calculate the total sum of weights on both pans before deciding which direction the scale will tilt.

Question 2(c). Pan weights: 245gm and 430gm vs 270gm and 315gm
Answer:
Total weight on the left pan = \(245\text{ gm} + 430\text{ gm} = 675\text{ gm}\)
Total weight on the right pan = \(270\text{ gm} + 315\text{ gm} = 585\text{ gm}\)
Since \(675\text{ gm} > 585\text{ gm}\), the left pan will go down.
In simple words: Find the total weight on both the left and right pans. The left pan has 675 grams which is heavier than 585 grams on the right pan, so the left pan goes down.

Exam Tip: Double-check your addition of grams to avoid careless calculation errors.
