StandardC2: Forms of Energy Students 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 bed light: sun, lamp, fluorescent tube, flame, sun reflected off a full moon sound: 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, falling chemical energy: photosynthesis, burning fuel, digesting food nuclear energy: fusion in the sun, fission in a nuclear power generator

Temperature changes from 100 to 120 let’s vote energy increased: 1 energy decreased: 1 energy stayed same: (everyone else?): 31

Temperature changes from 80 to 60 let’s vote energy increased: 1 energy decreased:2 energy stayed same: 30 (everyone else?)

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

How does temperature relate to energy? brothers sisters parents? direct relationship (increase or decrease together) inverse relationship (one increases, the other decreases)

3 ways heat can be produced? sleep ? boil water in a pan on the stovetop? meditation? explosions in the sun? outer space ? zap copper wire in an electrical outlet? frozen slushie at 7-11 ?

Plants and energy use... heat-light-chemical? 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 light plant: photosynthesis (chemical) growth: motion? heat-light-chemical? heat-nuclear-chemical? solar- heat- chemical?

multiple choice # 4-12 mechanical electrical nuclear heat light chemical sound energy solar cabedifgh

#13: fossil fuels Fossil 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. diagram: sun (nuclear, light, electromagnetic waves)  plants (chemical) decay (chem)  burning (chem)  motion (turning generator blades with moving steam)  electricity (motion and magnets near wire move current in the wire)

But... I missed those answers! these notes will be online at www.inksterscience.wikispaces.com or ask a friend who was paying attention  notes on page 4, # 2 and #3- please see Ms. Gall or work with a friend, relative, textbook, or online resource.
