This Grade 3 Science worksheet explores motion patterns and how forces let students predict future motion. Learners examine pendulums, rolling balls, and dropped objects to see repeating patterns. Through fill-in-the-blank sentences and matching activities, Grade 3 students connect friction, gravity, and balanced forces to motion changes, practicing prediction skills aligned with NGSS 3-PS2-2 and Grade 3 inquiry standards in class.
Style:
Forces and Motion
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A pattern of motion can be used to predict future motion.
2. A swing goes back and forth in a repeating pattern.
3. When a force stops acting, friction can slow an object down.
4. A ball thrown straight up comes back down because of gravity.
5. A rolling ball will keep going until a force stops it.
6. If you push harder, the object moves with more speed.
7. The path an object takes is called its direction of motion.
8. When no forces act, a resting object stays at rest.
9. A pendulum swinging the same way each time shows a regular pattern.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Swing pendulum
→ Repeats back and forth
Repeats back and forth
Friction on floor
→ Slows a rolling toy
Slows a rolling toy
Gravity on dropped apple
→ Pulls it straight down
Pulls it straight down
No forces acting
→ Object stays at rest
Object stays at rest
