= Types of Energy =

- A ball dropping
- Water moving down a "Hot Wheels" track

Electromagnetic Energy: Energy, such as light, which travels in waves, which has some electric and magnetic properties.
- Magnets - A flashlight - An ipod light on

Accustic Energy: The energy of sound
- An ipod on - Someone speaking - A harmonica playing

What We Will Need So Far: v Water v Dominoes v Stickers v Blocks v Cup v Hair Dryer v Golf Ball v Boat v Big Bouncy Ball v Elastic Rope

Purple is for Sally Green is for Caroline Robin Egg is for Both Orange is for Done

__ How a Circuit Works __

Batt ﻿ery ﻿ ﻿_Wire_ ﻿LIGHT!!!! ___Wire____ ﻿SameBattery

Chemical- battery Electromagentic- light Mechanical- switch Thermal- light Electrical- energy going through wires

It would be in a circle, but that's hard to do on this program :)

__What we Learned About Friction, Potential and Kinetic Energy, and Conversions from Energy Extravaganza__
= Potential and Kinetic Energy =

Potential Energy
Potential energy is the type of energy that has the potential to fall

Kinetic Energy
Kinetic energy is the energy that has movement involved with it.

Friction
With friction, we learned that it has acoustic, mechanical, and thermal energy. When there is too much friction on an object, it will stop moving. The cause of the object to stop moving is because the kinetic and potential energy converts to thermal, mechanical, and acoustic energy- causing the objects to eventually stop moving. Because of the air in our atmosphere, the mechanical energy will stop because of the friction in the air. Friction happens when one object rubs against another object.

Energy Conversions
=When an object is at the top of something (a swing, a half pipe, etc.) it has 100% gravitational potential energy. This means that the object has the potential to fall. When the object is at the bottom, it has 100% kinetic energy. When the object is somewhere in the middle of falling, it has 50% potential energy and 50% kinetic energy. =

**// Update 4/17/11 - We thought of a different way to dispense the sticker, in addition to our previous idea. If this idea doesn't work, we will still have previous idea to fall back on. We are still going to work on our previous idea though..... To Be Continued. //** **// Explanation of our Project: //**  Step 1) Brain sends impulse to body to eat food. (Electrical)   Step 2) A person eats food (Mechanical, Chemical, Electric) Step 3) The Brain sends impulses to different parts of the body to digest the food (Electrical)   Step 4) the person digests the food, turning it into energy for the body to use. (Mechanical, Chemical, Electrical) Step 5) The brain then sends impulses to other parts of the brain to think of giving someone a sticker (Electrical)   Step 6) The brain sends impulses to the muscles to grab the sticker. (Electrical) Step 7) the muscles in the arm/hand expand and contract to grab the sticker (Mechanical)   Step 8) the hand picks up the sticker (Mechanical) Step 9) the brain sends impulses to parts of the body to locate someone to give the sticker to. (Electrical and Mechanical because of eyes)   Step 10) the brain sends impulses to the hand to give the sticker to someone. (Electrical) Step 11) the muscles in the hand/arm expand and contract to give the sticker to someone. (Mechanical)   Step 12) the sticker drops into the hand of the person receiving the sticker. (Mechanical)
