Let's solve each of the problems on the "Comparing Mass" worksheet step by step. We’ll use the balance scales to determine which animal is heavier, lighter, or equal in mass.
---
1. Squirrel vs. Mouse
- The
squirrel side is lower than the mouse side.
- This means the
squirrel is heavier than the mouse.
✔ Answer:
*The
squirrel is heavier than the
mouse.*
---
2. Snake vs. Turtle
- The scale is
balanced, meaning both sides are equal.
- So, the snake and turtle have
equal mass.
✔ Answer:
*The mass of the snake is
equal to the mass of the turtle.*
---
3. Mouse vs. Snake
- The
snake side is lower (heavier), and the mouse side is higher (lighter).
- So, the
mouse is lighter than the snake.
✔ Answer:
*The
mouse is lighter than the
snake.*
---
4. Turtle vs. Frog
- The
turtle side is lower, so it’s heavier.
- The frog side is higher, so it’s lighter.
✔ Answer:
*The
turtle is heavier than the
frog.*
---
5. Fish vs. Frog
- The scale is
balanced — both sides are at the same level.
- So, their masses are
equal.
✔ Answer:
*The weight of the fish is
equal to the weight of the frog.*
---
6. Frog vs. Squirrel
- The
squirrel side is lower, so it’s heavier.
- The frog side is higher, so it’s lighter.
✔ Answer:
*The squirrel is
heavier than the frog.*
---
7. Snake vs. Rat
- The
rat side is lower → rat is heavier.
- The snake side is higher → snake is lighter.
✔ Answer:
*The rat is
heavier than the snake.*
---
8. Squirrel vs. Rat
- The scale is
balanced — both sides are even.
- So, they have
equal mass.
✔ Answer:
*The mass of the squirrel is
equal to the mass of the rat.*

🔍 Explanation:
- On a balance scale:
- If one side goes
down, that object is
heavier.
- If one side goes
up, that object is
lighter.
- If the scale is
level, the masses are
equal.
This worksheet helps students visually compare mass using real-world objects (animals) and practice using comparative language like "heavier," "lighter," and "equal."
