Why will the comb then attract small bits of paper? a. The comb has a magnetic attraction. b. The bits of paper have electric discharge. c. The comb and paper both have a negative charge. d. The comb has a negative charge. © LoveLearning 2014 $300 Answer from Static Electricity d. The comb has a negative charge. © LoveLearning 2014 $400 Question from Static Electricity What is it called when electrons move quickly from one object to another? © LoveLearning 2014 $400 Answer from Static Electricity Electric Discharge © LoveLearning 2014 $500 Question from Static Electricity Explain what happens when you rub a balloon on your head and then stick it to the whiteboard © LoveLearning 2014 $500 Answer from Static Electricity The balloon picks up electrons from your hair giving it a negative charge and then attracts to the positive charge of the whiteboard © LoveLearning 2014 $100 Question from Circuits Name the four parts of a circuit © LoveLearning 2014 $100 Answer from Circuits Battery, wire, switch, light bulb © LoveLearning 2014 $200 Question from Circuits What is the function of a battery in a circuit? © LoveLearning 2014 $200 Answer from Circuits It provides the “push” to keep electrons moving in the circuit © LoveLearning 2014 $300 Question from Circuits Explain one way to change a circuit © LoveLearning 2014 $300 Answer from Circuits • Adding more bulbs • Add another battery • Switch the wires around © LoveLearning 2014 $400 Question from Circuits Explain how a bulb works © LoveLearning 2014 $400 Answer from Circuits The filament wire is very thin, so electrons have a hard time passing through. When electrons do pass through, the filament becomes hot and begins to glow © LoveLearning 2014 $500 Question from Circuits In which part of a circuit is electrical energy changed into other forms of energy? a. The battery b. The switch The wire d. The load (anything that uses current to work) c. © LoveLearning 2014 $500 Answer from Circuits The load (anything that uses current to work) © LoveLearning 2014 $100 Question from Conductors/Insulators A conductor is: © LoveLearning 2014 $100 Answer from Conductors/Insulators a material through which electric charges can easily flow © LoveLearning 2014 $200 Question from Conductors/Insulators Name two examples of conductors © LoveLearning 2014 $200 Answer from Conductors/Insulators Copper Iron Gold Water Aluminum Steel silver © LoveLearning 2014 $300 Question from Conductors/Insulators An insulator is: © LoveLearning 2014 $300 Answer from Conductors/Insulators An insulator is a material through which an electric charge cannot easily flow © LoveLearning 2014 $400 Question from Conductors/Insulators Give three examples of insulators © LoveLearning 2014 $400 Answer from Conductors/Insulators Most plastics Glass Cloth Sand Rubber Wood Dry air © LoveLearning 2014 $500 Question from Conductors/Insulators Explain how you can test whether an object in an insulator or a conductor © LoveLearning 2014 $500 Answer from Conductors/Insulators Build a circuit and see if the object lights the bulb or not © LoveLearning 2014 $100 Question from Magnets What is a magnet? © LoveLearning 2014 $100 Answer from Magnets an object that can push or pull on iron without touching the metal © LoveLearning 2014 $200 Question from Magnets If the north poles of two magnets are close, they will: © LoveLearning 2014 $200 Answer from Magnets Repel © LoveLearning 2014 $300 Question from Magnets How can you turn a magnet into an electromagnet? © LoveLearning 2014 $300 Answer from Magnets © LoveLearning 2014 $400 Question from Magnets Draw the magnetic field © LoveLearning 2014 $400 Answer from Magnets © LoveLearning 2014 $500 Question from Magnets Name two advantages of electromagnets © LoveLearning 2014 $500 Answer from Magnets They can be turned on and off 2. They can be made stronger or weaker by changing the strength of the battery or wire loops 3. The direction of the fields can be changed (switch the poles) by switching the ends of the battery 1. © LoveLearning 2014 $100 Question from Pictures © LoveLearning 2014 $100 Answer from Pictures Electromagnet © LoveLearning 2014 $200 Question from Pictures Is this an open or a closed circuit? © LoveLearning 2014 $200 Answer from Pictures Open © LoveLearning 2014 $300 Question from Pictures What kind of circuit is this? © LoveLearning 2014 $300 Answer from Pictures Parallel © LoveLearning 2014 $400 Question from Pictures Why is important about this crane? © LoveLearning 2014 $400 Answer from Pictures It has an electromanget that can turn on and off © LoveLearning 2014 $500 Question from Pictures Draw a parallel circuit © LoveLearning 2014 $500 Answer from Pictures © LoveLearning 2014 Final Question In a series circuit that has two light bulbs, what happens to one of the light bulbs when the other bulb burns out? © LoveLearning 2014 Final Answer The good light bulb will also go out. © LoveLearning 2014
