  • What types of energy do we get from the sun?
    light and heat
  • What is an example of heat transfer through objects that are not touching?
    e.g. the sun heating up a sidewalk, roasting a marshmallow over a fire, using a space heater, etc.
  • Where does the energy come from to cook food on a solar cooker?
    The light from the sun. It transforms into heat to cook the food.
  • What is an example of stored energy transforming into light energy?
    e.g. when you burn a candle, when you snap a glowstick
  • How does electromagnetic radiation travel?
    It travels in waves
  • Do x-rays or radiowaves have more energy?
    x-rays have more energy. They have a smaller wavelength.
  • If you are touching a bowl of warm soup, what direction does the energy transfer?
    heat energy transfers from the warmer soup bowl to your cooler hands
  • What is the energy level of a cold object?
    it has low heat/thermal energy
  • What is an example of heat transfer by touching an object?
    e.g. warming hands on a bowl of hot soup, cooking pancakes on a griddle, etc.
  • Which form of energy transfers through vibrating particles?
    sound energy
  • How much energy do whispers have?
    they are a soft sound so they have low energy
  • How much energy do loud sounds have?
    high energy
  • Does sound travel faster through solids, liquids, or gasses?
    solids --> usually. Especially solids like metal
  • If an object has a high temperature, does it have high or low energy?
    high temperature = lots of heat = lots of thermal energy
  • How can you measure heat energy?
    You can use a thermometer
  • What type of energy do solar panels get from the sun to generate electricity?
    light energy from the sun is transformed into electrical energy
  • If you have an icepop at room temperature, what direction does the heat energy transfer?
    It transfers from the warmer air to the colder icepop.
  • Name 5 different types of energy
    types of energy: heat, EMR/light, sound, movement, electricity, chemical, gravitation, nuclear, elastic
  • Through which type of matter does sound move the slowest?
    gas, because the particles are farther apart
  • What type of EMR can we see?
    visible light
