  • Name the planets in order.
    Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
  • Why is there plastic around wires?
    Plastic is an insulator and blocks heat and electricity from flowing through.
  • Which object should the student move in order to complete a day and night cycle?
    Earth
  • What is a spring scale used to measure
    amount of force
  • What is it called when a liquid changes into a gas?
    evaporation
  • Why does the lightbulb not work in this circuit?
    It is not connected on both sides.
  • Around what time is shown in the picture?
    6-8am
  • What happened after the student stirred the mixture?
    The salt dissolved and made a saltwater solution
  • If the Earth is facing away from the sun, it is
    nighttime
  • If students wanted to know how the amount of force needed to drag a wood block across a surface is affected by the type of surface, what would they need to change in the experiment? What would stay the same?
    The type of surface would change but the amount of force, spring scale, and block would all stay the same for each trial.
  • What are they trying to determine in this experiment?
    How mass affects the force needed to move objects
  • Students paint the inside of several boxes a different color. They observe that the inside of the box that is painted white looks brighter than the other. Why is this?
    More light is reflected by white paint.
  • How long does it take the Earth to rotate once on its axis?
    24 hours/ 1 day
  • What could object 2 be?
    metal
  • How long does it take the Earth to orbit the Sun?
    365 days/ 1 year
  • Which lights would turn on in this circuit?
    Lightbulb 1 only
  • If the lightbulb on the right goes out, what will happen the lightbulb on the left?
    It will remain lit.
  • Which property of matter would be used to separate sand and iron filings?
    magnetism
  • In which season is the Earth tilted away from the Sun?
    winter
  • If the Earth is facing the sun, it is
    daytime
  • Complete the sentence: Solubility is the ability to dissolve. If something dissolves, it is _________ and will make a _________.
    If something dissolves, it is soluble and will make a solution.
  • Students look through the side of the aquarium and notice that the image of the tongs appears to break as the tongs enter the water. Which property of light are they observing?
    refraction
  • Around what time is shown in the picture?
    3-4pm
  • Predict which surface, concrete floor, carpet, or grass, that the balloon car will travel the least distance.
    grass, because it has more texture/more friction and will not travel as far
  • What causes seasons?
    The Earth's tilt as it orbits the sun
  • What is the magnetism of an iron nail?
    magnetic
  • the amount of matter in an object
    mass
  • How is light behaving as it encounters both materials?
    Material 1 it is refracting, material 2 it is reflecting
  • As air is released from the balloon, which way will the balloon car move?
    west
  • How would you separate a honey and water?
    evaporate the water
  • Why does it look like the sun rises and sets?
    The Earth is spinning (rotating) on its axis
  • The Moon ORBITS the Earth and ________ light from the Sun.
    reflects
  • Which object are less dense than water?
    toothpick, plastic paperclip, cork, and vegetable oil
  • What would you change to reduce the amount of force needed to move the masses?
    decrease the height of the ramp
  • Which 2 switches can be open and all the parts will still work?
    1 and 3
  • Which property of matter would be used to separate sand and water?
    state of matter --> separate with filter paper
  • Complete the sentence: all metals are ___________ but not all metals are ___________.
    all metals are CONDUCTORS but not all metals are MAGNETIC
  • Which surface provided the least amount of friction?
    concrete
  • In which season(s) is the Earth NOT tilted toward or away from the Sun?
    spring/fall

    the height of the ramp
  • Which substances dissolved in the water?
    Only the papain dissolved
  • In which season is the Earth tilted toward the Sun?
    summer
