  • When water freezes it will _________________.
    expand
  • What tool would you use if you were measuring an object in grams?
    a balance
  • What unit would you be measuring if you were using a graduated cylinder?
    milliliters
  • What happens when water is heated?
    It expands, in a thermometer, the red liquid would go up the stem.
  • What does EXPAND mean?
    Get bigger, increase
  • Name an object less dense than water.
    wooden bead, cork, toothpick
  • Do equal volumes of water and ice have the same mass? Explain.
    Yes, because even though ice takes up more space (it expands when it freezes), the mass does not change.
  • What does CONTRACT mean?
    Get smaller, decrease
  • Explain one way the Celsius and Fahrenheit scales are different.
    Celsius-Freezing is 0 degrees, Room Temp is 22 degrees, Body Temp is 37 degrees. Fahrenheit-Freezing is 32 degrees, Room Temp is 72 degrees, Body Temp is 98.6
  • When water expands, it becomes __________ dense, so it stays near the surface.
    less
  • What unit would you be measuring if you were using a measuring tape?
    centimeters
  • What happens when water is heated?
    It expands, in a thermometer, the red liquid would go up the stem.
  • If an object FLOATS in water, the object is __________ dense than water.
    less
  • Explain why this picture is incorrect.
    It should be warm, room temp, cold. Cold water is more dense than water so it sinks. Hot water is less dense than water so it floats near the surface.
  • When water contracts, it becomes ___________ dense, so it sinks to the bottom.
    more
  • All over the world the __________ sytem is used, but in the United States we use the ____________ system.
    metric, customary or English
  • What tool would you use if you were measuring an object in centimeters?
    measuring tape
  • Why does ice float?
    Ice is less dense than water.
  • What tool would you use if you were measuring something in milliliters?
    graduated cylinder
  • What tool is used to measure TEMPERATURE accurately?
    A thermometer
  • What unit would you be measuring if you were using a balance?
    grams
  • Name an object more dense than water.
    rubber stopper, penny, marble, paperclip
  • Draw a picture of cold water (use blue), warm water (use red), and room temperature water (clear) all in one vial. Where would each type of water settle?
    Top: warm Middle: room temp Bottom: cold
  • What happens when water is cooled?
    It contracts, in a thermometer, the red liquid would go down the stem.
  • If an object SINKS in water, the object is ______________ dense than water.
