200
This is 1000 watts.
What is a kilowatt?
200
This is the dependent variable in the appliance energy lab.
What is the amount of watts used?
200
This sink faucet had the most efficient water flow in the school building.
What is the bathroom faucet?
200
Any resource that can be replaced in a short period of time.
What is renewable resource?
300
He created the first electric cell used to make a battery.
Who is Alessandro Volta?
300
This is the unit used by the electric company to measure the electricity used to bill its customers.
What is kilowatt hour?
300
This is the independent variable in the Lightbulb Lab.
What is the type of lightbulb?
300
This lightbulb had the most efficient electrical cost of the two lightbulbs we tested in our Lightbulb Lab.
What is a CFL (compact fluorescent lightbulb)?
300
Examples are petroleum, propane, and natural gas.
What are nonrenewable resources? (These are fossil fuels.)
400
This type of electrical current was used in the first New York power plant to supply electricity to costumers within a mile.
What is direct current (DC)?
400
This is the amount of light from a light bulb.
What are lumens?
400
This is the dependent variable in the Lightbulb Lab.
What is the lightbulb temperatures?
400
This light bulb was more like a heat bulb since it gave off the most heat in our Light bulb lab.
What is an IL (incandescent lightbulb)?
400
Examples are geothermal, hydropower, and solar energy.
What are renewable resources?
500
This electrical current was used by the Niagara Falls power plant to transfer electricity to customers over 200 miles away.
What is alternating current (AC)?
500
This device measures the amount of power used by an appliance. (Hint: We used it in our appliance lab!)
What is a wattmeter?
500
The wattmeter and thermometer used in the Appliance Lab and Lightbulb Labs are examples of this variable.
What are controlled variables?
500
We learned that some appliances use electricity even when turned off.
What is vampire power (or phantom power)?
500
Nuclear power is an example of this.
What is a nonrenewable resource?
