TermDefinition
TICTEMP T-Time-Everything takes time I-Information-We need to know how and what to do C-Capital-MONEY! T-Tools & Machines-Tools extend our ability to work E-Energy-Movement M-Material P-People-Needs and Wants
What is Technology? Satisfies human needs and wants.
What is Energy? The ability to do work
What is Renewable Energy? Human and animal muscle power
What is Biomass Energy? Energy produced from organic substances (Ex. Trees, Wood Chips, Animal Waste, Sewage Plant)
What is Limited Energy? Energy that doesn't last forever (Ex. Coal, Petroleum, Nuclear Energy)
What is Unlimited Energy? Energy with no limit (Ex. Solar Energy, Wind, Gravity, Geothermal- Energy from below the surface, wave, and tidal)
What are 4 Types of Energy? -Potential -Stored -Kinetic -Energy in Motion
Sources of Energy- What is Solar? Energy from the sun
Sources of Energy-What is Gravitational? Hydroelectric systems make use of the energy in running water to create electricity
Sources of Energy-What is Geothermal? Heat from beneath the Earth's Crust
Sources of Energy-What is Chemical? Energy from chemical reactions

Where does Electricity come from? Power plants, Batteries, Wind, Turbines, Generators, Solar Power
How do you control Electricity? Plugs, Switches, Fuses, Circuit breakers, Wires, Plastic
What is an Insulator? A material whose atoms hold their outer electrons tightly. Resisting the flow of electrical currents through the material
What are examples of an Insulator? Wood, Rubber, Glass
What is a Conductor? A material whose atoms easily give up their outer electrons. Letting an electrical current flow easily through the material.
