History
The ability to do work.
What is energy?
Humans have been using this type of energy for many purposes for thousands of years. The use of this energy is a major achievement that helps humans cook food, warm their bodies, and have light in the darkness.
What is fire?
The colors of the wavelength that are visible to the human eye.
What is the visible light spectrum?
An imbalance of positive and negative charges in an object.
What is static electricity?
Energy resources that are reusable and sustainable because they never run out, that are sourced from the earth, and that do not emit harmful by-products into the earth's environment.
What is renewable energy?
Energy cannot be created or destroyed buy can change from one form to another.
What is conservation of energy?
The Egyptians were the first civilization to build and ride on these boats. Wind energy was used to move the boats forward.
What is a sail boat?
The act of quickly moving back and forth.
What is vibration?
The rate at which electrons move through a circuit as caused by the voltage.
What is a current?
Energy resources that are sourced from the earth and that can and do run out.
What is nonrenewable energy?
Energy in motion.
What is kinetic energy?
In 1752 Benjamin Franklin proved that lightning and static electricity were the same thing. In order to prove the theory, this was flown in a thunderstorm with a metal key connected to the bottom. A charge was felt from being near the lightning.
What is a kite?
Pressure caused by vibration traveling through a medium such as air.
What is sound waves?
A complete electrical path.
What is a circuit?
An effort to use less energy and seek out alternative sustainable energy sources.
What is conservation?
Energy that exists but is not being used.
What is potential energy?
Around 300 BC, people harnessed the energy of flowing water. This was an important step because people realized that water joined human muscle, animals, fire, and wind as a source of energy. Humans were expanding their use and understanding of where energy is and how to harness it.
What is a waterwheel?
An object that retains its magnetism after being magnetized.
What is a permanent magnet?
A magnetic force surrounding something, such as the earth, that can force electrically charged particles to align in a particular path.
What is a magnetic field?
Cole Rasengerger was only in second grade when he learned that forests in North Caroline, USA, were being cut down at an alarming rate. He organized an effort at his school to write postcards to McDonald's, asking the company to use this in packaging. McDonald's committed to use this product.
What is recycled paper?
A state of balance between opposing forces or actions.
What is equilibrium?
In 1800 Alessandro Volta created this. At the time, it was called a voltaic pile. Over the next 100 years other scientists and inventors were able to improve the creation and mass-produce. The storage of energy became more portable.
What is a battery?
A magnet created by running electricity through a copper wire wrapped around a core of material that can be magnetized, such as iron, steel, or nickel.
What is electromagnet?
When magnets and electrical currents interact.
What is electromagnetism?
Alex Lin was 11 years old when he came up with the idea to salvage old computers and use parts to build computers for children in countries without access to new technology.
What is project WIN?
(Westerly Innovations Network)
