Let's solve this Grade 3 Science worksheet step by step, using the provided word bank:
Word Bank:
balanced, opposite, equal, force, unbalanced, move, change shape
---
1. A push or a pull is a _____________.
-
Answer: *force*
-
Explanation: In science, a push or a pull is called a
force. This is the basic definition of force.
---
2. When forces acting on something are _____________ the object will move or _____________.
-
Answer: *unbalanced*, *change shape*
-
Explanation: When forces are
unbalanced, they are not equal in size or direction, so the object will either
move or
change shape (like being stretched or squished). The image shows a chef rolling dough — that’s changing shape due to an unbalanced force.
---
3. When forces acting on something are _____________ the object will not _____________.
-
Answer: *balanced*, *move*
-
Explanation: When forces are
balanced, they are equal and opposite, so they cancel each other out. The object stays still — it does
not move. The seesaw image shows two children of equal weight, so the forces are balanced and the seesaw doesn’t move.
---
4. Balanced forces push on _____________ sides of something with _____________ strength.
-
Answer: *opposite*, *equal*
-
Explanation: Balanced forces act on
opposite sides and have
equal strength. The image shows two hands pushing on a book from both ends — if they push equally, the book won't move. That’s a balanced force.

✔ Final Answers:
1. A push or a pull is a
force.
2. When forces acting on something are
unbalanced, the object will move or
change shape.
3. When forces acting on something are
balanced, the object will not
move.
4. Balanced forces push on
opposite sides of something with
equal strength.

This worksheet teaches the difference between
balanced and
unbalanced forces and how they affect motion and shape. Great for building foundational science understanding!
Parent Tip: Review the logic above to help your child master the concept of force and shape worksheet.
