Grade 3 Sheet 3 challenges learners to predict outcomes in circuits and around magnets. Grade 3 students answer four multiple-choice questions about adding bulbs, using magnets on mixed objects, opening switches, and pushing like poles together. Five fill-in-the-blank items extend the reasoning to cut wires, compass behavior, and extra batteries. The sheet trains Grade 3 thinkers to use cause-and-effect rules of electricity and magnetism to forecast what will happen next in a setup they have never seen.

Electricity and Magnetism
Part A: Multiple Choice
Circle the best answer for each question.
1. Grade 3: In a circuit, one bulb lights up. If you add a second bulb in a simple loop with the same battery, what is most likely to happen?
A) Both bulbs glow a little dimmer
B) The first bulb glows twice as bright
C) The battery instantly becomes fully charged
D) Both bulbs will not light at all under any condition
2. Grade 3: A student places a bar magnet near a pile of items. Which object will the magnet pull toward itself the most?
A) An iron paper clip
B) A rubber eraser
C) A wooden pencil
D) A piece of paper
3. Grade 3: If you flip a switch from closed to open in a circuit with one bulb, what happens next?
A) The bulb turns off because the loop is broken
B) The bulb glows brighter than before
C) The battery starts to heat up the wires instantly
D) Nothing changes at all in the working circuit
4. Grade 3: Two bar magnets are slid toward each other with their north poles facing. What will you most likely feel and see?
A) They push apart and resist coming together
B) They snap tightly together right away
C) They spin around in a fast circle
D) They heat up until they glow brightly
Part B: Fill in the Blank
Write the correct answer on each line.
1. If you cut a wire in the middle of a working circuit, the bulb will go out.
2. Two south poles held close together will repel each other, not pull together.
3. A magnet will not pick up a plastic button because plastic is non-magnetic.
4. Adding a second battery in the same direction to a circuit often makes the bulb glow brighter.
5. When a compass is placed on a table far from metal, its needle points toward north.
