1. Lesson 3

2.  Turbine Generators spin to cause copper wire and magnets to create electricity.  Water, wind and steam are what spin a turbine.  Turbine – A machine with blades that spin

3. Answer the 3 questions on the back of your student reading page.

4.  Energy can be neither created nor destroyed.  Energy can only be transformed from one form to another  Energy is constant Laws of Thermodynamics Total amount of energy in the universe is constant. Energy can be neither created nor destroyed, but it can be changed from one form to another

5.  The ability to do work or create change  Energy can be potential (stored) or kinetic  Potential (stored) energy: energy that is stored in some way  Kinetic energy: energy of motion, involves movement of some kind

6.  Write the definition  Write 1 example

7.  Energy an object has due to place or position, such as its height above the Earth; a form of potential energy  Rock on the edge of a cliff, water behind a dam.

8.  Energy stored in the chemical bonds between atoms and molecules  Energy plants store by photosynthesis, any food we eat, coal, oil

9.  Energy stored in the nucleus of an atom; the energy that holds an atom together; sometimes called atomic energy  Uranium in a nuclear power plant and plutonium in a bomb

11.  The energy of an object or substance in movement; sometimes just called kinetic energy  Person dancing, car in motion, a thrown ball, flowing water.

12.  The energy of electrons moving or flowing within a substance  Power lines or home wiring, electricity from a battery

13.  Electromagnetic energy that travels in waves; also called radiant energy  Sunlight, the light of a lamp or of a TV, or computer monitor

14.  The internal energy of a substance due to random vibration and movement of its atoms and molecules; also called thermal energy.  Heat form the burner of a stove, charcoal grill, forest fire.

15.  Energy that moves through substances by compression waves; sound  Any kind of sound from humans, machines, animals, Ipods

16. Review: Energy can be neither created nor destroyed, but it can be transformed.  Light bulbs convert electric energy to light energy  Movement of our bodies converts chemical energy to kinetic energy  School bell converts electric energy to sound energy  Coal to electricity to light  Natural gas to heat to stove Brainpop: Forms of energy
