- 1. You Need:<br />Scientist’s Notebook<br />Pen <br />Pencils<br />Art Supplies<br />
- 2. Make a list of everything you did this morning from the time you got up until the time you walked into the school.<br />
- 3. Did you use any of these things?<br />
- 4.
- 5. What is one thing that they all have in common?<br />They all involve energy<br />
- 6. Energy<br /><ul><li>The ability to do work or make something happen</li></ul>But….<br />What is work?<br />
- 7. Work<br />Using force (a push or pull) to make something move through a distance <br />
- 8. So energy is…<br />The ability to make something move or make something happen or the ability to do work<br />
- 9. What are the different types of energy?<br />List as many as you can think of in your Scientist’s Notebook.<br />
- 10. There are only 2 types of energy:<br />Potential<br />Kinetic<br />
- 11. Potential<br />Kinetic<br />Make your chart <br />Look like this<br />
- 12. Potential Energy<br />Energy that is stored. <br />Hasn’t been used yet.<br />2 Causes of Potential Energy:<br />1. An object’s position<br />
- 13. <ul><li>An object’s position</li></ul>(2 Ways)<br />Because of vertical position or height<br />More height = more energy<br />Caused by gravity<br />
- 14. Potential Energy based on Position<br /><ul><li>Caused by Gravity
- 15. Because of vertical position or height.
- 16. More height = More energy</li></li></ul><li>More height = more energy…<br />Which has more potential energy?<br />
- 17. What about this? When they both finish moving their objects to the top, which object will have more potential energy?<br />
- 18. <ul><li>An object’s position</li></ul>(2 Ways)<br />(Being stretched beyond its normal position)<br />Because of vertical position or height<br />Position can be like spring or bow and arrow<br />More height = more energy<br />Because of Elasticity - elastic<br />Caused by gravity<br />
- 19. PE because of Position<br />Because of Elasticity - elastic<br />
- 20. PE because of position…<br />
- 21. PE because of position…gravity or elasticity?<br />
- 22. <ul><li>An object’s condition</li></ul>Like a battery,<br />Gasoline or the bonds between something’s atoms<br />Because of its atoms<br />
- 23. Potential energy can also be because of an object’s condition.<br />
- 24. Potential<br />Kinetic<br /><ul><li>Energy that is stored
- 25. Hasn’t been used yet.
- 26. Comes from:
- 27. An object’s position
- 28. An object’s condition</li></ul>Caused by gravity<br />Position can be like spring or bow and arrow<br />More height = more energy<br />Because of vertical position or height<br />Like a battery,<br />Gasoline or the bonds between something’s atoms<br />Because of its atoms<br />
- 29. Once the energy is put to use it becomes….Kinetic Energy<br />Energy in motion<br />Energy that’s being used<br />
- 30. Potential energy (stored energy) gets converted to kinetic energy, (or energy of motion).<br />
- 31. More examples….<br />
- 32.
- 33. What are some examples of potential and kinetic energy?<br />
- 34.
- 35.
- 36. More about Potential and Kinetic Energy<br />Brainpop on Potential and Kinetic Energy<br />
- 37. Now it’s your turn:<br /><ul><li>Think of an example of potential and kinetic energy.
- 38. You will be making a flip book to illustrate your example.
- 39. Let’s make our book first.</li></li></ul><li>Take your white paper and fold it in half horizontally.<br />
- 40. <ul><li>Fold in half again.
- 41. Unfold the last fold you made.
- 42. Take your scissors and cut along the fold line on the top flap only.</li></li></ul><li>Label one side “Potential Energy” and the other side “Kinetic Energy”<br />
- 43. <ul><li>On your other sheet of white paper, make a practice drawing. Don’t use much detail. It’s not your real one.
- 44. Give me the signal to approve it.
- 45. Start your real drawing in your flip book.
- 46. It must be colored, and your words must be in ink.
- 47. Do the whole thing in pencil first, then go over it with markers, colored pencils, etc. (In case you mess up!)</li></li></ul><li>BBC Web Activity<br />There’s more!<br />
- 48. There are 2 types of energy:<br />Potential<br />Kinetic<br />Energy can exist in many forms:<br />(Video Clip)<br />
- 49. Forms of energy:<br />http://www.brainpop.com/science/energy/formsofenergy/<br />
- 50. Forms of energy<br />Mechanical <br />Heat <br />Chemical<br />Electrical<br />Radiant<br />Nuclear<br />Sound<br />
- 51. Make your notes<br /> look like this:<br />Fit 2 energy forms per page!<br />Draw a quick picture of one example of each energy form<br />
- 52. Mechanical Energy<br />Energy of moving objects<br />
- 53. Heat (or thermal) Energy<br /><ul><li>Energy from quick moving molecules or atoms</li></li></ul><li>Chemical<br /><ul><li>Energy stored in atoms and molecules because of their bonds.
- 54. Ex: natural gas, propane, coal, biomass</li></ul>What’s biomass?<br />
- 55. Electrical<br />Energy produced when electrons flow (or move).<br />Ex: Lightning, electricity<br />
- 56. Radiant<br />Electromagnetic energy that travels in waves through empty space<br />Ex: light, x-rays, radio waves, solar energy<br />
- 57.
- 58. Nuclear<br />Energy stored in the nucleus of an atom<br />The force that holds the neutrons and protons together is very strong. If you break that bond, it releases LOTS of energy!!<br />
- 59. <ul><li>Intro to Nuclear Energy
- 60. Nuclear Medicine
- 61. The Bomb</li></li></ul><li>Sound <br />Sound is energy??? You bet!!<br />Energy that moves in waves through substances.<br />
- 62. Sound energy travels in waves.<br />
- 63. Let’s talk more about Heat Energy or Thermal Energy<br />Remember that it’s the energy caused by the movement of particles in an object.<br />Turn to the next available page in your Scientist’s Notebook.<br />At the top write HEAT<br />Make a T-Chart<br />
- 64. I didn’t know that…<br />I knew that!<br />Make sure you <br />List 5 things on <br />Each side!<br />Make your chart <br />Look like this<br />
- 65.
- 66. Let’s compare lists.<br />
- 67. What is heat?<br />Energy from an object’s moving particles.<br />The faster the particles are moving, the more heat energy the matter has.<br />Thermal Energy<br />
- 68. Temperature is…<br />A measure of how fast an object’s particles are moving.<br />Measured with a thermometer<br />So…thermometers don’t measure Heat. They measure temperature!<br />
- 69. Heat…<br />Always moves from warmer matter to cooler matter! <br />Memorize this!!!!<br />When heat moves,<br />It’s called…<br />
- 70. Heat Transfer<br />(or How Heat Travels)<br /><ul><li>Conduction
- 71. Convection
- 72. Radiation</li></ul>http://www.wisc-online.com/objects/index_tj.asp?objID=SCE304<br />
- 73. Conduction<br /><ul><li>When heat moves from particle to particle because they are touching each other.
- 74. Happens mostly in solids
- 75. Only happens when particles are TOUCHING!!!
- 76. Example: A pot on a stove eye heats up because the fast moving particles of the eye bump into the particles of the pot, and the energy is transferred.</li></li></ul><li><ul><li>When an object’s particles get heated, the particles move faster and bump into the nearby particles.</li></li></ul><li>Convection<br /><ul><li>Heat is transferred by the heated matter moving.
- 77. Occurs in liquids and gases
- 78. Steps:
- 79. Matter is heated and becomes less dense.</li></li></ul><li><ul><li>Since the heated matter is less dense, it rises.
- 80. The cooler matter slides in to take its place.</li></li></ul><li>Convection, cont.<br /><ul><li>Example: Boiling water- The water at the bottom is heated, expands, becomes less dense, then rises. The water above is still cool, so it sinks</li></li></ul><li>Convection causes thunderheads.<br />
- 81. Convection causes wind – especially at the beach!<br />
- 82. Convection helps us heat our home, cool our food, and even cook our food!<br />
- 83. Radiation<br /><ul><li>When heat moves (or radiates) through empty space.
- 84. Doesn’t need to travel through matter like conduction or convection.</li></li></ul><li>
