What is the difference in electricity generation between solar panels and power plants like wind, coal, and nuclear?
Solar panels produce more harmful radiation than the others.
Coal, wind, and nuclear are cleaner than solar.
Solar is non-renewable, while coal, wind, and nuclear are.
Solar panels don't use electromagnetic induction.
Which Pokémon uses hydropower?
Pikachu
Charmander
Bulbasaur
Squirtle
Why don't bouncy balls return to their starting height when dropped without an applied force?
gravity becomes stronger near the ground
the inertia is greater than the starting potential energy
it should, but doesn't because gravity is acting on the ball
friction converts kinetic energy into thermal energy
Why is it important for battery technology to improve within the alternative energy field?
to store energy for when energy availability is lacking
they'll explode if overused
to clean the electricity from coal power plants
to make electricity needed for windmills and solar to work
How do solar panels generate electricity?
PV cells absorb light energy and convert it to electrical
heliostats direct thermal energy to turn water into steam
PV cells absorb thermal energy and convert it to electrical
heliostats direct light energy to turn water into steam
How could electromagnetic induction be produced? (2 options)
by rotating either the metal wire or magnetic field together
with electricity being applied to a magnet
with a changing magnetic field surrounded by plastic wires
none of the above
Which Pokémon can harnesses solar power?
Bulbasaur
Pikachu
Squirtle
Charmander
Why do incandescent (old fashion) light bulbs require more energy than LED (modern) light bulbs?
they use a 3-prong plug
more energy is converted to thermal instead of radiant
more energy is converted to radiant instead of thermal
they are larger than LED
True or False: A downfall to nonrenewable resources is that they can take as long as 10 years to replenish.
False
How do solar thermal power plants generate electricity?
heliostats direct light energy to turn water into steam
PV cells absorb light energy and convert it to electrical
heliostats direct thermal energy to turn water into steam
PV cells absorb thermal energy and convert it to electrical

look directly into the sun
True or False: Fossil fuels are made from the fossils of dinosaurs and prehistoric plants.
False
Why do most power plants use turbines to generate electricity?
to create excessive amounts of static electricity
to make the mechanical motion for electromagnetic induction
to put heliostats in position to generate more electricity
to stoke the coal fire needed to generate electricity
According to the law of conservation of energy, what is the 2nd energy conversion that takes place when fossil fuels are used to generate electricity?
stored chemical energy transforms into thermal energy
touching fire with your bare hands
thermal energy transforms into mechanical energy

mechanical energy transforms into electrical energy
thermal energy transforms into mechanical energy
getting struck by lightning
stored chemical energy transforms into thermal energy
What kind of resources are coal, water, and wood?
man-made resources
non-renewable resources
