How is electricity made
what are the three methods to power a generator
Steam, water, wind
what is special about the Christmas tree in the Enoshima Aquarium in Japan?
it is powered by an electric eel.
what is an alternative to gas powered cars?
electric cars
what is the name of the energy campaign in the UK?
Student Switch Off
a light, durable, silver colored metal often used in soda cans
aluminum
what is inside a generator that creates electricity?
magnets
where do electric eels usually live?
in streams and ponds of South America
which car can go at a faster speed?
the gas powered car
When and where did student switch off begin?
At the university of East Anglia in the UK in 2006
the vapor (gas) that is released when water is heated up or boiled
steam
what is the problem with using steam for generators?
it releases carbon and pollutes our environment
How many cells do electric eels have, and how much electricity can they generate?
they have about 6,000 cells that can give off 500-600 volts of electricity
How are gas powered and electric powered cars fueled/charged?
a gas powered car needs only five minutes to refuel at a gas station, while an electric car may need to be charged for 6-7 hours.
what are the things that student switch off encourages students to do?
turn off lights and appliances, wear sweaters instead of turning on the heat, and put lids on pans when cooking
able to be charged again
rechargeable
although water powered generators are relatively clean, what is the problem caused by them?
they can have harmful effects on plants and animals that live in the water.
what is the purpose of the electric eel powered christmas tree?
it is to promote eco-awareness and show a new way to generate electricity that does not hard the environment.
how do electric cars get their energy?
through energy stored in a rechargeable battery
How many universities participate in student switch off?
40
the harmful CO2 gas released, often bu trains, cars, and busses
emissions
what is the problem with wind powered generators?
Wind is not reliable because it does not blow all the time.
explain how eel can light the christmas tree.
The electricity is captured by two aluminum panels in a special tank. The panels act like a battery to collect electricity given off by the eel when it moves, then the electricity travels to the lights on the tree.
explain the environmental impact of both gasoline and electric cars
gas powered cars release CO2 emissions into the atmosphere, while electric cars need to use a lot of electricity to be made which use fossil fuels.
How does student switch off spread its message?
they use social networking sites (social media)
a place to live usually at schools and colleges
residence hall
