The Purple Ninjas- Molly Jones and Kate Striefel = ﻿__Definitions__: = = __﻿Energy__- The ability to do work or cause change. = = __Kinetic Energy__- The energy of motion. An example of kinetic energy is a ball rolling down a hill. = = __Potential Energy__- Energy that is stored and held in readiness. An example of potential energy is water behind a dam. = = __Chemical Energy__- The energy passed from one source to another. An example of chemical energy is a human eating corn. = = __Electromagnetic Energy__- A form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. An example of electromagnetic energy is an X-Ray. = = __Acoustic Energy__- The energy that comes from music. An example of acoustic energy is an iPod. = = __Mechanical Energy__- Describes the sum of potential energy and kinetic energy present in the components of a mechanical system. Mechanical energy is the energy associated with the motion or position of an object. An example of mechanical energy is a person riding a bicycle. = = __Electrical Energy__- Energy made available by the flow of electric charge through a conductor. An example of electrical energy is a lamp plugged into an outlet. = = __Thermal Energy__- The total energy of a substance particles due to their motions or vibrations. Also, the energy of motion in the molecules of a substance. An example of thermal energy is a lightbulb heating up when the light is turned on. = = __Light Energy__- The radiant energy of electromatic waves in the visible portion of the electromagnetic spectrum. An example of light energy are Christmas Lights. = = __Nuclear Energy__- Energy released by reactions within atomic nuclei, as in nuclear fission or fusion. An example of nuclear energy is the Sun. = = __﻿How Energy Could Be Used In Our Project__: = = __Kinetic__- Have an object roll down and up a hill. We could have an object go through a loop on a track. We could have an object fall off of a slope. = = __Potential__- Have an object fall onto another object. We could have an object placed on a shelf or other place higher than the ground. We could have an object pull back and shoot. = = __Chemical__- Have a lamp light up via wires and batteries. We could have a hot object burn a little hole into another object. We could have a toy animal eating another object. = =__ Mechanical __ - Have a toy bike with a person on it so it looks like the person is pedaling. We could have an object fall when it's on a rope or chain. We could have an object hook onto another object. = =__ Thermal __ - Have an object heat up and spit something out of it. We could have an object heat up from a battery. We could have an object heat up from being plugged into a wall. = =__ Acoustic __ - Have music playing as the train goes across it. We could have an object roll over a xylophone. We could have a boombox playing throughout the project. = =__ Electromagnetic- __ Have an object light up through a few different wires. = =__ Electrical __ - Have electricity to make the music play out of an old boombox/ CD player. We could have an object plugged into the wall to work. We could have a home- created circuit made to produce electricity. = = __﻿Can We Tell About Batteries and Energy Flow?__ = = Yes, we can! We had to do a flashlight lab in Science where we had to build a flashlight out of objects such as a Christmas Tree light- To provide the light for the flashlight = = Toilet Paper Tubes- To provide the shelter for the batteries and wires = = Gatorade or Milk Carton Cap- To provide shelter for the christmas tree light. May add a different color to your flashlight's light. = = Copper Wires- To provide a place for electricity to flow from the batteries to the christmas tree light. = = Batteries- Energy stored in these and are passed from the copper wires to the christmas tree light. = = When we built our flashlight, it was a real challenge. It wasn't so hard making the light light up as it was to make the switch to light the light up. We finally ended up getting the flashlight to work, and we were able to turn it in for a grade. = = How the Energy was Passed- The energy in the batteries were passed through the copper wires and into the lightbulb, making it light up. The types of energy in this project were = = Chemical- In the batteries that was passed through the wires into the light. = = Electromagnetic- Making the wires able to pass the energy. = = Light- To make the lightbulb light up. = = ﻿__Friction, Potential, and Kinetic Energy Explanation__- = = We learned a lot about Friction, Potential, and Kinetic energy in the energy extravaganza project we had to do. What we learned about friction was that everytime an object hits or rubs against something, it is considered a form of friction. What we learned about potential energy was the higher up an object is in the air, the more potential energy it has. When the object falls down, the less potential energy it has. We also learned about kinetic energy. We learned that when an object is moving, falling, etc., that is an example of kinetic energy. That is what we learned about Friction, Potential, and Kinetic energy during the Energy Extravaganza. = = ﻿__Energy Conversions__- = = Another thing we learned during the Energy Extravaganza was about energy conversions. Energy conversions are when one type of energy becomes another type of energy. An example of an energy conversion would be if a hot iron was burning holes in a pair of pants. This energy conversion would be Thermal Energy into Chemical Energy. Another energy conversion would be a bird cage opening a door to allow music to play. This energy conversion would be Mechanical Energy to Acoustic Energy. That is some of the information we learned about energy conversions during the Energy Extravaganza. = = ﻿__Energy in a Closed System__- = = During our Flashlight Lab, we had to learn how Energy flows in a closed system. What we learned was that first the energy goes from the main source (in this case, the batteries,) and flows through the conductor (the copper wires,) to the main source needing the energy (the Christmas tree light.) = = ﻿__How Energy is Never Lost__- = = Many people don't know it, but energy is never lost. What energy does is it converts into another form of energy from it's previous one (as explained in the Energy Conversions section above.) Many different types of Energy conversions happen everyday. An example of an Energy Conversion is when an iron burns a pair of pants (Heat Energy to Chemical Energy.) That is how we know that energy is never lost. = = __Notes for Project__: = = __Theme__- Musical Racetrack =
