Energy 101
Energy Forms and Transformations Essential Question Where does energy come from? How is energy transformed/transferred in our daily lives? We need to understand the basics of energy before understanding solar energy.
What is energy? Ability to do work or cause change Produces Warmth Produces Light Produces Sound Produces Movement Produces Growth Powers Technology
Jigsaw Energy Forms In your groups, write down what you know about these types of energy: Stored Mechanical Thermal Nuclear Sound Electrical Chemical Gravitational Radiant Motion
Potential Energy Gravitational Energy energy an object or substance has because of its position Anything up high
Potential Energy Stored Mechanical Energy stored in an object by the application of force Must push or pull on an object
Potential Energy Nuclear Energy energy stored in the nucleus of an atom Holds the atom together
Potential Energy Chemical Energy energy stored in the bonds between atoms Holds molecules together
Kinetic Energy Mechanical (Motion) Energy movement of objects or substances from one place to another
Kinetic Energy Electrical Energy movement of electrons
Kinetic Energy Sound Energy movement of energy through substances in the form of longitudinal/compres sion waves
Kinetic Energy Radiant Energy electromagnetic energy that travels in transverse waves
Kinetic Energy Thermal (Heat) Energy internal energy of a substance due to the vibration of atoms and molecules making up the substance
Forms of Energy POTENTIAL CHEMICAL STORED MECHANICAL NUCLEAR GRAVITATIONAL KINETIC ELECTRICAL RADIANT THERMAL MOTION SOUND
Classes of Energy POTENTIAL KINETIC Stored energy or energy of position Gravitational, Stored Mechanical, Nuclear, Chemical Energy of motion Motion, Electrical, Sound, Radiant, Thermal
Energy Transfers 1 Energy can not be created nor destroyed, only changed. Law of Conservation of Energy First Law of Thermodynamics 2 Energy will always transfer from high to low. 3 No energy transfer is 100% efficient.
Electrical Energy
Electricity Basics Electricity is.. The flow of electrons The energy sent out by batteries and generators (current electricity) The shock you can get from rubbing your feet on the carpet (static electricity) A bolt of lightning! (static electricity)
All Matter is Made up of Atoms MATTER (Diamond, coal) ELEMENT (Carbon, Oxygen) ATOM (particles)
Atoms What is an Atom? The smallest component in all things Made up of three smaller particles Protons (+) Neutrons (no charge) Electrons (-) Strive for stability Charged atom = ion
Opposites Attract Attraction + + Particles with opposite charges attract each other.
Atoms Charged Atom (Ion) +++ --- Stable Atom Positive Ion -- Negative Ion Stable atoms have equal protons and electron Stable atoms have no charge Free electrons will seek positively charged ions to create stability
Electricity Simulation Opposites Attract Find a match! Simulate Current Electricity
Simulating Electric Current
Current Electricity Electric current is the movement of free electrons from atom to atom To start the free electrons moving an electromotive force is needed. Batteries Generator
Current is like water flow Flow of water is similar to flow of electrons The pressure (voltage) determines how fast the water (electrons) move through the pipe (wire) There is no current without voltage Flow Flow 4/22/2016 42
Voltage & Current Voltage Pushes electrons Measured in Volts Comes from batteries, electric outlets, generators Current Flow of electrons Measured in Amps 1 amp = 6,240,000,000,000,000 electrons moving past a point every second 4/22/2016 43
How is Electrical Energy Generated? Coal Plant Simulation (Adapted from NEED.org, Primary Energy Stories and More, A Cool Coal Story)

How Do You Get Electricity?
Where Does Arizona Get Electricity? There are 10 sections. Think in terms of fractions or percentages. If you color in 5 sections, that would be 1 2 or 50%. If you colored in 3 sections, that would be 1 3 or 30%. Try to think of all the resources Arizona uses. Assign a value to each.
