This Grade 3 science worksheet builds pattern-of-motion skills using pendulums, ramps, and swings. Students read short observations, then fix three grammar sentences, complete four fill-in blanks, and decide three true or false claims. Each item focuses on predicting the next position using a repeating pattern. Vocabulary includes pattern, predict, ramp, swing, gravity, and stop, aligned to NGSS 3-PS2 and Grade 3 classroom language for beginning motion learners.

Forces and Motion
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A pendulum swings in a pattern, so we can predicts where it goes next.
Rewrite: A pendulum swings in a pattern, so we can predict where it goes next.
2. Fix the sentence:
The ball roll down the ramp faster each second.
Rewrite: The ball rolls down the ramp faster each second.
3. Fix the sentence:
The swing go back and forth in a repeating pattern.
Rewrite: The swing goes back and forth in a repeating pattern.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A pendulum swings in a repeating pattern that we can observe.
2. A ball rolling down a ramp speeds up because of gravity pulling it.
3. A swing that is pushed once will slow down and finally stop.
4. If a pattern repeats, we can predict what will happen next.
Part C: True or False?
Read each statement. Circle True or False.
1. A pendulum in Grade 3 science moves in a repeating pattern we can predict.
True False
2. A ball rolling down a steeper ramp moves slower than one on a flat ramp.
True False
3. A swing with no push will eventually stop because of friction and air.
True False
