Mass and volume exercise - Free Printable

Here are the solutions to the problems on the worksheet.

1. Put in order the balls from heavy to light.

To solve this, we look at what the balls are made of and how dense they usually are:
* Bowling ball (Blue): These are very solid and heavy so they can knock down pins. This is the heaviest.
* Metal ball (Silver): Metal is heavy, but a small ball like this is lighter than a bowling ball.
* Rubber/Tennis ball (Pink): This is light enough to bounce easily.
* Beach ball (Multi-color): This is filled with air and is very light.

Order: Bowling ball $\rightarrow$ Metal ball $\rightarrow$ Pink ball $\rightarrow$ Beach ball.

2. Select the item with more volume.

Volume means how much space an object takes up. Let's look at the pairs:
* Pair 1: The glass bottle holds much more liquid than the small soda can.
* Pair 2: A watermelon is much bigger and takes up more space than an apple.
* Pair 3: A large suitcase is bigger and holds more things than a school backpack.

Selections: The Bottle, The Watermelon, The Suitcase.

3. Order these objects depending on their volume.

We need to rank them from smallest amount of space to largest amount of space:
1. Trash bin: This is the smallest object here. It fits in a corner of a room.
2. Bathtub: This is bigger than a bin because you can fit a person inside it, but it is smaller than a boat.
3. Barrel: A standard barrel is quite large. While a canoe is long, a fat barrel often has more total volume (space inside) than a narrow canoe. *Note: In many elementary exercises, the "Boat/Canoe" is sometimes considered larger due to length, but typically a bathtub is ranked smaller than a barrel or boat. Let's look at standard sizes. A trash bin is ~50-100 liters. A bathtub is ~150-300 liters. A barrel is ~200 liters. A canoe is ~300-400 liters.*
* Let's re-evaluate based on visual size in typical textbook logic:
* Smallest: Trash bin.
* Next: Bathtub (holds a person).
* Next: Barrel (often used as a unit of large volume).
* Largest: Canoe (long and wide enough for people + gear).
* *Alternative interpretation:* Sometimes the Barrel is seen as smaller than the Canoe. Let's stick to: Bin < Bathtub < Barrel < Canoe OR Bin < Bathtub < Canoe < Barrel. Actually, looking at the picture, the canoe looks very long. However, barrels are very thick. Let's go with the most common sense order for "capacity":
1. Trash bin (Smallest)
2. Bathtub
3. Barrel
4. Canoe (Largest - because it carries multiple people)

*Self-Correction:* Actually, looking at the icons, the canoe is labeled with a "1". If "1" means the first in the sequence (smallest), that would be wrong because a canoe is huge. If "1" is just a label, we ignore it. Usually, these questions ask for Smallest to Largest.

Let's try Largest to Smallest? No, usually it's ascending.
Let's look at the items again.
- Trash bin: Small.
- Bathtub: Medium-Large.
- Barrel: Large.
- Canoe: Very Large.

So the order from Smallest to Largest is: Trash bin, Bathtub, Barrel, Canoe.

Final Answer:

1. Order from heavy to light:
1. Blue Bowling Ball (Heaviest)
2. Silver Metal Ball
3. Pink Ball
4. Beach Ball (Lightest)

2. Items with more volume:
* The Glass Bottle
* The Watermelon
* The Green Suitcase

3. Order by volume (Smallest to Largest):
1. Trash bin
2. Bathtub
3. Barrel
4. Canoe
