Grade 3 Sheet 3 explores electromagnets and everyday magnet tools. Grade 3 students fill in nine blanks about compasses, junkyard cranes, refrigerator magnets, magnetic poles, and how current creates magnetism. They then match four common magnet applications to the specific job each one performs. The sheet guides Grade 3 learners to see that magnets appear in many useful places and that switching an electromagnet on and off is a powerful tool. Hints and explanations reinforce science vocabulary.
Style:
Electricity and Magnetism
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A magnet made by wrapping wire around iron and running current through it is an electromagnet.
2. A compass has a tiny magnet that lines up with Earth to point North.
3. A junkyard crane uses a huge electromagnet to lift heavy steel cars.
4. The two ends of a bar magnet are called the north and south poles.
5. Two north poles pushed together will repel each other.
6. A north pole and a south pole will attract each other.
7. Turning off the current in an electromagnet makes its magnetism stop.
8. A refrigerator magnet sticks to the door because the door is made of steel.
9. An electromagnet is stronger when you add more loops of wire around the iron.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
