A: Two wires connected on each side of a D-Cell is connected to a bulb. B: A wire from a D-Cell is connected to a bulb. C: Two wires on one side of a D-Cell is connected to a bulb. A 1 - $200 In a complete circuit, the D-Cell A: Is the pathway for electricity B: Gives power to the circuit C: Takes away power from the circuit. B. 1 - $300 What is the role of a switch in a circuit? A: Turns the circuit left and right. B: Switches the flow of protons in the circuit. C: Opens and closes the circuit. C 1 - $400 How do D-Cells need to be arranged in order for a circuit to work? A: Negative to negative B: Negative to positive C: Positive to positive. B 1 - $500 How many pathways does a parallel circuit have to flow? A: one B: two C: 3 B 2 - $100 How can you make an electromagnet stronger? A: Wind the wire more times on a rivet B: Use a thinner wire C: Use a thicker wire A 2 - $200 Which one of these DON’T you need to build an electromagnet? A: a magnet B: a wire C: a rivet A 2 - $300 What is a rivet? A: An iron object that can be magnetized B: A body of water. C: A component that gives power to an electromagnet. A 2 - $400 What materials are needed to build an electromagnet? A: a rivet, wire, and motor B: a rivet, wire, and D-Cell C: a rivet, wire, and magnet B 2 - $500 Electromagnets are an example of A: induced electricity B: induced conductors C: induced magnetism C 3 - $100 A paper clip stuck to a permanent magnet was able to pick up a small washer. The nail could pick up the washer because… A: the nail was a magnet B: nails and washers are made of iron C: the nail was experiencing induced magnetism. C. 3 - $200 A magnet attracted a nail even when a pack of post-its was placed in between it. Then, when someone tried to put a small sponge between the magnet and nail, the nail fell. Why? A: Magnetism can travel through paper and not sponges. B: The sponge soaked up the magnetism. C: The distance between the magnet and nail was too far: it was out of the magnet’s field. C 3 - $300 Which object is NOT magnetic? A: Screw B: Paperclip C: Aluminum Foil C 3 - $400 Which material is magnetic? A: Magnetite B: Aluminum Foil C: Plastic A 3 - $500 An object is magnetic if it contains: A: Iron or Copper B: Aluminum or Metal C: Iron or steel. C 4 - $100 Insulators A: a component that turns a circuit on and off. B: Keeps a circuit warm C: A material that does not allow electricity to flow. C 4 - $200 An open circuit is A: one that allows electricity to flow B: one that allows electricity to grow C: one that electricity does not flow. C 4 - $300 A series circuit is A: One that has only one pathway that electricity can flow. B: One that has multiple pathways that electricity can flow. C: A circuit with no sense of humor. A 4 - $400 A conductor is A: A material that electricity runs to. B: A material that stops electricity. C: A material that electricity runs through. C. 4 - $500 Electromagnet A: When a magnetic field is induced by an electric current. B: When an electric field is induced by a magnetic current. C: When a baseball field is produced by a magnetic current. A 5 - $100 Rubber band A: Magnetic B: Not B 5 - $200 Screw A: Magnetic B: Not A 5 - $300 Aluminum Foil A: Magnetic B: Not B 5 - $400 Magnetite A: Magnetic B: Not A 5 - $500 What sticks to a magnet, but does not conduct electricity? A: Magnetite B: Cardboard C: Aluminum Foil A Final Jeopardy You have three magnets and a variety of objects. How could you tell which magnet is the strongest? Answers will vary!
