 Energy is the ability to do work or cause change.  It can be transferred from one object to another.  Potential Energy is stored energy, or “energy of position”  Kinetic Energy is the energy of motion. Think about the roller coaster. It has both types of energy.

Lesson 1 Energy conservation and conversion Six different types of energy: pg Mechanical = kinetic + potential Sound - results from vibration of particles Electromagnetic - transmitted as EM waves Chemical - stored in chemical bonds Thermal/Heat - due to motion of molecules Nuclear - comes from atom’s nucleus

Lesson 1 Energy conservation and conversion Energy Transformation- when energy changes from one form to another. Law of Conservation of Energy- states that energy cannot be created or destroyed, but can change forms. Efficiency- the ratio of useful output energy to input energy. Vocabulary: pg. 454

Lesson 1 Energy conservation and conversion Examples of different types of energy: Mechanical: moving car Sound: hearing a car Electromagnetic: x-rays Chemical: food Thermal: heat Nuclear: sun generating energy

Lesson 1 Energy conservation and conversion Examples….in your own words! Write an example of energy transformation. Write an example of the law of conservation of energy Write an example of efficiency.

Lesson 2 Temperature Vocabulary Kinetic theory of matter- states that all particles that make up matter are constantly in motion. Temperature- a measure of the amount of kinetic energy of the particles in an object. Degrees- equally spaced units between two points Thermometer- instrument used to measure temperature.

Lesson 2 Temperature Particles of a solid vibrate in position and are close together Particles of a liquid slide past each other and tumble over each other Particles of a gas move quickly and are far apart States of matter

Lesson 2 Temperature Temperature Scales Celsius- Most commonly used around the world and in science Fahrenheit- Used in US and developed in 1700s Kelvin- Used by physicists and units are “kelvins”. Developed in 20 th century

Lesson 2 Temperature C=(F-32)5/9 F=C(9/5) + 32 K=C

What am I?

Lesson 2 Temperature How is temperature related to kinetic energy?

Lesson 3 Thermal Energy and Heat Thermal Energy- total kinetic energy of all particles in a substance. Heat - the energy transferred from an object at a higher temperature to an object at a lower temperature. Vocabulary

Lesson 3 Thermal Energy and Heat How is thermal energy different from temperature? Temp= average kinetic energy Thermal= total kinetic energy more molecules = more thermal energy

Lesson 3 Thermal Energy and Heat HOTtoCOLD

Lesson 3 Thermal Energy and Heat Vocabulary Calorie - amount of energy needed to raise the temperature of 1g of water by 1  C. This is one way to measure heat. Conduction - transfer of energy as heat from one substance to another through direct contact.

Lesson 3 Thermal Energy and Heat Vocabulary Conductor - A material that transfers heat very well. Metals are an example. Insulator - Materials that are poor conductors of heat. Examples include wood, paper, plastic foam

Lesson 3 Thermal Energy and Heat Vocabulary Convection - The transfer of energy as heat by the movement of a liquid or gas. Occurs when cooler, denser matter replaces a warmer, less dense mass by pushing it upward. Radiation- The transfer of energy by EM waves.
