Gabby L. and Mackenzie M. Information:

1. Forms of Energy: Mechanical Energy- The enrgy associated with the motion or position of an oblect. Example:The school bus. Thermal Energy- The total energy of particles in an object. Ex: stove, overn, microwave Chemical Energy- Potention energy stored in chemical bonds that hold chemical compuonds together. Ex: matches Electric Energy- Moving electric charges that produce electricity. Ex: when you rub your socks on the carpet, then shock someone Electromagnetic Energy- The light that you can see each day. Ex:The light you see each day

2. Thermal: Warm smoke filling a balloon Light: Light from the match

Mechanical: Dolphin Thing Grabbing the sticker pushing dominoes

Chemical: Lighting a match

Acoustic: The sound of the dominoes hitting each other.

4. Friction is slowing down energy in the form of heat or acoustic energy. Kinetic and potential energy transfers from one to another. Potential energy is when energy is stored and the energy source is at rest. Kinetic energy is energy in motion when the enrgy source is not in rest. For example, there is a ball at the top of a ramp, right now the ball has all potential energy. When the ball is starting down the hill it still has a lot of potential energy, but some of it has conferted to kinetic energy. By about half way down the hill it is about 100% kinetic energy and when it gets to the bottom it has all of the potential energy back again.

Project Video/ Photos:



First we had this starting idea:



Then it turned into the project we had in our video. I saw a bunch of old tech deck stuff that my brother had used and my mom and dad helped come up with the idea, we tested it and it worked. Here is how it works. The first thing is the hex bug that we turn on and it goes back and pulls the energy doplhin that knocks over dominoes and then that hits the ping pong ball that hits more dominoes, then knocks over a ball that hits the skateboard, which delivers the sticker.
