This Grade 3 hard worksheet mixes forces, magnets, and circuits in tougher multiple choice and fill-in questions. Students decide which objects a magnet attracts, identify non-contact forces, and explain why an open switch keeps a bulb dark. They also match conductors and insulators such as copper and rubber. The activities deepen Grade 3 NGSS 3-PS2-3 reasoning about cause and effect in everyday science.
Style:
Electricity and Magnetism
Part A: Multiple Choice
Circle the best answer for each question.
1. Which object would a magnet most likely attract?
A) A plastic ruler
B) A wooden pencil
C) A steel paper clip
D) A rubber eraser
2. Which is an example of a non-contact force?
A) Kicking a soccer ball
B) A magnet pulling a nail from across the table
C) Pushing a door open
D) Lifting a box with your hands
3. Why does a circuit with an open switch have a dark bulb?
A) The battery is empty
B) The bulb is broken
C) The circuit is open, so electricity cannot flow
D) There are too many wires
4. Which pair shows materials that are a conductor and an insulator?
A) Copper wire and iron nail
B) Rubber band and plastic cup
C) Copper wire and rubber band
D) Wood block and paper sheet
Part B: Fill in the Blank
Write the correct answer on each line.
1. A magnet is strongest at its north and south poles.
2. Two south poles pushed together will repel each other.
3. A metal spoon is a conductor because electricity can flow through it.
4. Rubber gloves keep electricians safe because rubber is a great insulator.
5. When two magnets pull together without touching, they show a non-contact force.
