Q?: The battery is an example of what type of energy?

Ms. Smith Mrs. Malone Energy Transformations November 6, 2012 • DO NOW: • Date: November 6, 2012 • Put your CB on your desk • Read the Do Now Reading • Q?:In paragraph 4, what does converted mean? 6.9C demonstrate energy transformations such as how energy in a flashlight battery changes from chemical energy to electrical energy to light energy.

Introduction to Energy Transformations • Read the first paragraph on pg. 51 of Gateways to Science Grade 6. • Look at the example below, tracing back a car’s energy: • Make your own diagram tracing back the energy in a toaster as far as you can go. The sun gets its energy from the atoms inside it. The sun is the source of almost all the energy on earth. The car’s moving energy comes from burning fuel. Fuel’s chemical energy comes from decomposed micro-organisms that lived in the sea The tiny animals get their energy from plants, which get their energy from the sun.

MRS CENT Foldable COMPLETE THE FOLDABLE USING THE INFORMATION BELOW: • MECHANICAL- energy generated through movement • RADIANT (light or solar)- the energy of electromagnetic waves. • SOUND-vibration that moves through a solid, liquid, or gas to our ears • CHEMICAL- energy released from chemical reactions • ELECTRICAL- energy generated through electricity • NUCLEAR- energy released during a nuclear reaction, generally fusion or fission • THERMAL(heat)- energy that changes the temperature of an object.

Name that energy form!

Ms. Smith Mrs. Malone Group Member Roles November 7-8, 2012 • Yellow- Materials Manager • Only person allowed out of seat during lab • Obtains and returns all lab materials • Blue- Safety/Clean-up Manager • Enforces all safety rules • Green- Activity Director • • Reads directions to the group • • Keeps group on-task • Red- Data Manager • Records all data • Ensures all group members have lab data :

Name that energy form! • The ball is less dense than the water, so the water pushes the ball back to the surface. • The electrons in the magnet are attracted to the iron in the paperclip. • This attractions pulls the paperclip to the magnet. • The dish soap causes the fat in the milk to break down and move away from the other fat particles. • The food coloring lets us see the movement caused by the reaction between the soap and the fat. • Striking the tuning fork causes air molecules to bounce between the two forks. This creates sound and moves the ping pong ball.

Energy Transformation Stations Your hand transferred moving or mechanical energy to the ping pong ball. Mechanical to Mechanical • The magnet pulls the paperclip towards it, using electromagnetic energy to move the paperclip (which becomes mechanical energy) . • Electromagnet to Mechanical • Sound is a form of mechanical energy because it is produced by moving air particles. • Mechanical to Sound • The dish soap broke down the bonds in the milk, causing it to move. • Chemical to Mechanical
