Electricity Grade 4

made for jadyn

What is a closed circuit? a continuous, closed path for electricity to flow through
What does repel mean? push away
What does repel have to do with static electricity? This happens when you have two statically charged items which have the same charges.
What is the difference between an open and closed circuit? An open circuit will not work because there is a gap in the transfer, possibly from an open switch. A closed circuit has no gaps and will work.
Who invented the light bulb? Thomas Edison
List some conductors. nail, wire, foil, paperclip
What is the difference between conductors and insulators? Conductors will allow the flow of energy to go through them; insulators stop the flow of energy.
What does attract mean? come together
What does attract have to do with static electricity? When two items are statically charged and they have opposite charges, they will be attracted to each other.
Why might a flashlight not work? There may be a gap. There might not be a strong enough source. There could be an insulator in the path or same charges could be connected.
What labels do you need on a circuit? bulb (receiver), battery (source), wire (transfer), and switch
What does it mean if a circuit is open? There is not a path for the electricity to flow. The switch could be up (open).
What is the term for the tiny, horizontal wire inside a light bulb? filament
What are the scientific terms for the positive, negative and neutral charges? protons (+), neutrons (0), electrons (-)
What causes something to have a static charge? Static charges result from two objects exchanging charges; resulting in an even amount of protons (positive charges) and electrons (negative charges).
In a circuit, what is the scientific term for the wire? transfer
In a circuit, what is the scientific term for the light bulb? receiver
In a circuit, what is the scientific term for the battery? source
What are the steps of the scientific method? 1. Ask a question 2. State your hypothesis 3. Identify control/variables 4. Test your hypothesis 5. Collect & record data 6. Interpret data 7. Draw a conclusion 8. Go Further
What might happen if we added 2 more batteries to the simple circuits we created? Explain why this might happen. The bulb might burn out because there is more electricity being sent to the bulb than it can handle.
Would a light bulb work if both wires are connected to the positive side of the batter? Why or why not? No- the bulb is not receiving a negative charge.
Which of these items would be the best conductor in a circuit: foil, a large nail, or a pencil? a large nail because it is a stronger (more solid piece of metal)
Explain 2 things you should be careful of to keep yourself safe around electricity. Do not combine liquids/water and electricity; do not touch open wires; do not touch the metal of a working circuit; do not put metal into a working circuit.
How could you make a battery last longer? Put it in the freezer or turn battery-operated items off when finished.
What are the charges of each of the three atoms? protons are positive; electrons are negative; neutrons are neutral/no charge
What are the 2 key words to use when writing a strong hypothesis? if, then
A continuous path for the flow of electricity is called what? circuit
Name 5 things which use electricity. lamps, blow dryers, pencil sharpeners, phones, TVs
