  • what type of energy does a light bulb emit?
    light energy / electromagnetic radiation
  • A very low sound, like a tuba, will have a (LONG/SHORT) wavelength
    long
  • Name at least 5 different types of energy
    heat, EMR/light, sound, movement, electricity, chemical, gravitational, nuclear, elastic
  • Why do engineers share their results?
    to show what works and what doesn't work
    so they can stop redesigning
    to keep their ideas secret
    to make other people do the work
  • does sound travel faster through solids, liquids, or gasses?
    solids --> usually. Especially solids like metal.
  • Which of these objects has the most motion energy?
    a fast moving bowling ball
    a fast moving ping pong ball
    a slow moving bowling ball
    a slow moving ping pong ball
  • What types of energy do we get from the sun?
    heat and light/EMR
  • a low energy wave will have a (TALL/SHORT) amplitude
    short
  • What does conservation of energy mean?
    Energy can be neither created nor destroyed, it can only transfer to other objects or change form
  • which form of energy transfers through vibrating particles?
    sound energy
  • How do you measure amplitude?
    You measure from the middle line/resting point to the crest or trough
  • Through which type of matter does sound move the slowest?
    gas, because the particles are farther apart
  • Why is working with other people helpful in science and engineering?
    you can blame somebody else if you make a mistake
    you can share your ideas
    other people do all the work
    it makes the project cost less money
  • A student can only use paper and tape to build a bridge. What is this?
    constraint
    data
    criteria
    solution
  • Which step comes at the end of the design process?
    build a prototype
    brainstorm ideas and pick a solution
    share your results
    do background research
  • Name at least 2 types o energy that a television gives off?
    heat, light, sound
  • Why is it important to only test one change at a time in an experiment?
    so you know what caused the result
    so that experiments last longer
    so the tests are shorter
    so the teacher is happy
  • Sound is made when:
    absorbed energy turns into heat
    objects vibrate
    waves travel through space
    particles interact with light
  • Why does a bouncing ball not bounce as high each time?
    some energy is changed to heat and sound, some energy is transferred to the ground
  • When energy is transferred in a collision, what three things can you observe?
    heat, sound, change in motion energy/direction
  • An egg-drop design breaks the egg. What should students do?
    do background research on designs
    give up and go home
    improve the design and test again
    say that it worked
  • What happen's to a stretched or compressed spring's energy when it is released?
    it converts to chemical energy
    nothing happens, it stays the same when it's released
    it becomes motion energy
    the energy disappears
  • What type of energy from the sun do solar panels use to generate electricity?
    light
    color
    sound
    heat
  • If a sound is very loud, will the sound wave have a high or low amplitude?
    high amplitude
  • What is the energy level of a cold object?
    it has low heat/thermal energy
  • What is an example of stored energy transforming into light energy?
    e.g. when you burn a candle, when you snap a glowstick, when you use a battery to power a flashlight
  • What type of energy do solar panels get from the sun to generate electricity?
    light energy from the sun is transformed into electrical energy
  • When you touch a metal spoon in a bowl of hot soup, why does it feel hot?
    heat moves from your cooler hand into the warmer spoon
    the heat disappears and then reappears in the spoon
    heat moves from the warmer soup into the cooler spoon
    the collision of your hand and the spoon transfers energy
  • How can you give more motion energy to a soccer ball?
    Possible answers: you can kick it, you can make it move faster
  • When two objects collide, energy can transfer and make:
    electricity and chemical energy
    sound and electricity
    heat and chemical energy
    sound and heat
  • What type of energy does a light bulb use?
    electricity / electric energy
  • What is most important when testing a raincoat?
    how warm it feels
    how well it keeps out water
    how much it costs
    the color of the material
  • How does increasing volume affect the amplitude of a sound wave?
    louder volume = larger amplitude
