ENERGY Turn to the very last page of your composition notebook. Write at the top of the page: Test Reflections Write on the first line: Test 2 Then answer these questions: *Which questions (and learning targets) did I miss? *Why did I miss those questions? (silly mistakes, didn't understand it, need more practice, etc.) DO NOW MONDAY List as many types of energy as you can. WHAT IS ENERGY? Energy is: the ability to do work. the ability to cause things to happen PROPERTIES OF ENERGY 1. Energy is always conserved- it cannot be created or destroyed. This means the amount of energy in the universe is always CONSTANT. PROPERTIES OF ENERGY 2. Energy can be transferred or transformed Transferred (moved) from one object to another- it is still the same form of energy (ex. mechanical to mechanical) Transformed (changed) into other, different forms (ex. mechanical to thermal) DIFFERENT FORMS OF ENERGY Kinetic- energy of motion Potential- stored energy Thermal • Gravitational Heat-due to motion of particles Light/Solar • Radiant (transferred as waves) Electrical • From electrons moving Sound • Transferred as waves Mechanical • Anything that has moving parts • Energy an object has due to its height Chemical • Stored in the bonds that hold atoms together Nuclear • Stored in nucleus of atoms ENERGY SONG https://www.youtube.com/watch?v=_uLSFigtLKg DO NOW TUESDAY What type of energy does a hair dryer involve? RUBE GOLDBERG Rube Goldberg was a very creative man. He was a cartoonist, an engineer, an inventor, a sculptor, and a writer. He had a “knack” for designing a very complex path to complete a very simple task. His designs became known as “Rube Goldbergs” The path to the completion of a task always contained many transfers and transformations of energy.

A H C-D G D-E F B I J E-F F-G C D G-H E H-I I-J SCORING GUIDE FOR RUBE GOLDBERG PROJECT: • 12 steps or more • Action • Energy form(s) • Energy Transfer or Transformation • Drawings neat (You tried your best) • Colored Drawings Exit Slip Tuesday Does the picture show an energy transfer or transformation? Explain. DO NOW WEDNESDAY Name the energy transfers/transformati ons that are happening in the Rube Goldberg device pictured. A-B= B-C= C-D= D-E= E-F= F-G= G-H= DO NOW THURSDAY For each picture (1-5), write the energy transformation taking place. 1 2 3 4 5 DO NOW THURSDAY Does the picture show an energy transfer or transformation? Explain. DO NOW FRIDAY Does the picture show an energy transfer or transformation? Explain.
