This Grade 3 hard worksheet challenges students to think about magnetic poles and non-contact forces. Multiple choice and fill-in questions ask about like poles repelling, unlike poles attracting, and how magnets can work through thin materials. The sheet also compares magnetism with gravity and with contact forces like pushing, helping Grade 3 learners meet NGSS 3-PS2-3 expectations for investigating invisible forces.
Style:
Electricity and Magnetism
Part A: Multiple Choice
Circle the best answer for each question.
1. What happens when the north pole of one magnet meets the north pole of another?
A) They attract each other strongly
B) They repel each other
C) They stick together forever
D) They lose all their magnetism
2. Which pair of poles will attract each other?
A) North and north
B) South and south
C) North and south
D) East and west
3. A magnet can often pull a paper clip that is behind a thin piece of paper. Why?
A) The paper is a magnet too
B) Magnetism can work through some thin materials
C) The paper clip is jumping on its own
D) The magnet is touching the paper clip directly
4. Which of these is NOT a non-contact force in Grade 3 science?
A) Magnetism
B) Gravity
C) Electric force
D) A push from your hand
Part B: Fill in the Blank
Write the correct answer on each line.
1. Two north poles near each other will repel each other away.
2. A north pole and a south pole will attract each other.
3. Magnetism is called a non-contact force because magnets can work without touching.
4. Gravity is another non-contact force that pulls things down to Earth.
5. When you push a toy car with your hand, that is a contact force.
