1. Put your CB on your desk2. Read the Do Now ReadingQ?: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 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.
The sun gets its energy from the atoms inside it. The sun is the source of almost all the energy on earth.
MRS CENT FoldableCOMPLETE 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.

Ms. SmithMrs. Malone
:
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

-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.
- Striking the tuning fork causes air molecules to bounce between the two forks. This creates sound and moves the ping pong ball.
-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.

-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.
