  2. The picture below shows a light bulb. The bottom of this light bulb is an example of what type of simple machine? Screw

  3. On a warm summer day, most of the sun’s rays will be _______ when they strike the black shirt below. Absorbed

  4. The picture below shows a duck swimming in a lake. A student sees a mirror image of a duck in the water of the lake. What causes this mirror image? Reflected Light

  5. What happens to the path of a light ray as it passes from air into water at an angle? Refraction - It bends

  6. There are three types of materials that light waves can hit. One type allows all of the light waves to travel through. One type allows some of the light waves and one allows no light waves to travel through. What is the name of each type of material? Transparent - All Translucent - Some Opaque - None

  7. When an electric fan is running, most of the incoming electrical energy changes into which kind of energy? • Heat energy • Light energy • Mechanical energy • Sound energy Mechanical Energy

  8. When a light bulb is turned on, energy changes from one form to another. Which of the following best describes this change? • Sound energy to radiant energy • Nuclear energy to radiant energy • Electrical energy to radiant energy • Magnetic energy to radiant energy C. Electrical to Radiant

  9. After Nita connected a copper wire from one terminal of a battery to the other, the wire became very hot. Why did the wire get hot? • A.The circuit was not complete • Air around the wire became • electrified • C. Chemical Energy in the battery • produced vibrations • D. Electrical energy was changed • into thermal energy D. Electrical energy was changed into thermal energy

  10. The following pictures shows earphones connected to an ipod. In this system, which type of energy is used to make the information from the ipod travel to the earphones to make sound? Electrical

  11. Which of the following is an example of a chemical change? • Your hair being cut. • An automobile using gas to run • The liquid in a glass of water freezing • A piece of wood being cut to build a deck b. An automobile burns gasoline (chemical energy) to make it move (mechanical energy)

  12. When a light switch is turned on what has happened to the circuit? It has become a CLOSED CIRCUIT

  13. The picture below shows a circuit. What would happen if the second bulb is removed from the circuit? What type of circuit is pictured below? Series Circuit - If one bulb is removed all the lights will go out because they are connected in one loop.

  14. Marta has an iPod docking station in her room. It requires electricity in order to play. Which of the following is necessary in order for electricity to move from the source to the radio? • A circuit • A magnet • A light bulb • An insulator A. A circuit

  15. The picture below shows a circuit. What would happen if the middle bulb is removed from the circuit? What type of circuit is it? It is a parallel circuit. The other bulb would stay on because each bulb has its own pathway to the electricity.

  16. DAILY DOUBLEName the most common metal used as a conductor in wires. Name two common materials used as insulators. Copper Glass, Plastic, or Rubber

  17. If a string on a musical instrument, like a guitar, is made tighter the sound produced by the string will always be lower pitched or higher pitched? Higher Pitched
