The scientific law that states energy cannot be created or destroyed, but energy can change form.
What is the Law of Conservation of Energy?
100
Nonrenewable resources that we get out of the earth like petroleum, coal and natural gas.
What are fossil fuels?
100
Energy of motion ...kicking...karate...kayak...keyboard...knock...
What is kinetic energy?
200
Energy of moving electrons.
What is electrical energy?
200
The primary energy conversion in your biscuits and gravy to walking to school.
What is chemical to kinetic?
200
These forces cause thermal energy in every conversion.
What is friction and air resistance?
200
Energy resource that we rely on heavily for electricity. This causes a great deal of air pollution. It holds potential chemical energy from the sun.
What is coal?
200
This is the thing in the experiment the scientist collects data on and measures.
What is the dependent variable.
300
Kinetic energy due to the random motion of the particles in an object.
What is thermal energy?
300
The primary energy conversion in the growing of an apple.
What is light energy to chemical energy?
300
A machine that would run forever with no additional energy, but is not possible to build because of thermal energy.
What is a perpetual motion machine?
300
This energy resources is not polluting, but is very limited as you must be near a river to use the power of falling water to turn a turbine to generate electricity.
What is hydroelectric energy?
300
All of the kinetic and potential energy combined.
What is mechanical energy?
400
Energy of a compound that changes as its atoms are rearranged.
What is chemical energy?
400
The primary energy conversion from uranium to electricity.
What is nuclear to electrical?
400
Energy that is present in every conversion but is not used to do any work. This energy causes roller coasters to never be able to go back to the highest height.
What is wasted thermal energy?
400
Hot spots in the earth's crust can be used to heat water to make steam to turn a turbine, like in Iceland. OR heat from the ground can be used with open and closed loop systems to heat and cool schools in Warrensburg.
What is geothermal energy?
400
This is the thing in the experiment the scientist changes on purpose to set up the experiment.
What is independent variable? (IV)
500
Energy from tiny amounts of matter. When the nucleus of an atom is changed.
What is nuclear energy?
500
All the energy conversions in using a blender.
What is electrical to kinetic, sound, and thermal?
500
Energy conversion in this invention are electrical to light to thermal. 100 J = 20 J light energy and 80 J thermal energy
What is a incandescent light bulb?
500
A very concentrated form of energy. The nuclei of atoms are split apart which releases energy to heat water to make steam to turn a turbine. This produces radioactive wastes. Special safety systems must be in place in these power plants.
What is nuclear energy?
500
During your experiment, the factors that you must keep the same to have a fair test.
