Tuesday, January 4, 2011DO NOW: Name and give examples of 4 types of

energy.HOMEWORK: Complete worksheets (2pgs) due Thurs.AIMS: StandardC2: Forms of EnergyLESSON STEPS:

1. Complete and record Do Now and Homework in notebook.

2. Review Lesson Steps.3. Discuss Do Now activity.4. Notes and Discussion: 2 page worksheet5. Review: Conservation of Mass packet and quiz: Turn in

your packet if you haven’t already! (was due in December)

StandardC2: Forms of EnergyStudents recognize the many forms of energy and

understand that energy is central to predicting and explaining how and why chemical reactions occur. The chemical topics of bonding, gas behavior, kinetics, enthalpy, entropy, free energy, and nuclear stability are addressed in this standard.

Chemistry students relate temperature to the average kinetic energy of the molecules and use the kinetic molecular theory to describe and explain the behavior of gases and the rates of chemical reactions. They understand nuclear stability in terms of reaching a state of minimum potential energy.

Energy Worksheets (2pgs, f/b)(two pages, fronts and backs printed)“page 2 of 9”: front page (label with name, date,

hour)“page 2” (Answer Key): NOTES! Read this page

first.“page 3 of 9”: 5 questions“page 7 of 9”: 13 questions

ALL FOUR PAGES ARE RELEVANT TO THE TOPIC OF FORMS OF ENERGY.

WE HAVE NOT COVERED ALL, BUT ALL ARE EASY TO FIND.

ALL ARE VALUABLE FOR TEST PREPARATION ALSO.

examples:heat: stove, sun, burner, heater, fire, lamp,

tanning bedlight: sun, lamp, fluorescent tube, flame, sun

reflected off a full moonsound: IHS students talking, hitting the table,

radio, phone, announcer at a football game, electrical: batteries, outlets, phone charger,

phone, iPod, hair dryer,energy of motion: running, jumping, throwing,

pushing, pulling, fallingchemical energy: photosynthesis, burning fuel,

digesting foodnuclear energy: fusion in the sun, fission in a

nuclear power generator

Electricity flows through a wire.How is the flow of electricity related to the

temperature of the wire? both increase together (direct relationship)

when one increases, the other decreases (inverse relationship)

no relationship

Plants and energy use...Plants use energy to survive. They use the sun’s

energy to make the food they need to grow and develop. Which energy sequence best describes the transformation that takes place in plants?

sun: heat and lightplant: photosynthesis (chemical)growth: motion?

heat-light-chemical? heat-nuclear-chemical?

solar- heat- chemical?

#13: fossil fuelsFossil fuels contain energy that originally

came from the sun. Explain how we can state that electricity from a coal- burning generator plant received its energy from the sun.
