  • Carlos has a chocolate box whose length is 12 cm, height 8 cm, and width 6 cm. What is the volume?
    L x H x W 12 x 8 x 6 = 576 CM3
  • True or False: Mass divided by volume is the density.
    True!
  • The amount of space matter takes up.
    Volume
  • The amount of matter in an object.
    Mass
  • A measure of the force of gravity on an object.
    Weight
  • The change of state that takes place when water vapor in the air forms a cloud is called...
    Condensation
  • The amount of matter in a given volume.
    Density
  • What are the three states of matter?
    Solid, Liquid and Gas
  • What is the formula to calculate density?
    Mass divided by volume. or D=M/V
  • How do you find the volume of a cube or rectangular prism?
    L x H x W
  • What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 29.4 cm3?
    D = M/V 25/29.4 = 0.85 G/CM3
  • True or False: When finding the volume of an irregular shaped object the last step is to subtract the initial and final water levels?
    True!
  • What are the three parts of an atom?
    Proton, Neutron, Electron
  • A set of beads has a mass of 3.2g. It displaces 15 mL of water. What is its density?
    D = M/V 3.2/15 = .21 G/ML OR .21 G/CM3
  • Anything that has mass and takes up space.

  • A candle sitting on the table near a window starts to drip wax on the table. The wax dripping is an example of what phase change?
    Melting
  • The part of the experiment that changes.
    Independent Variable
  • The thing in an experiment that changes as a result of a change in a different variable.
    Dependent Variable
  • The science tool used to find the mass of an object.
    Balance, Triple beam balance, beam balance.
  • Changing from a liquid to a solid is called...?
    Freezing
  • Which has more mass, a brick or a large sponge the same size as the brick?
    A brick, because it doesn't have holes in it the way a sponge does. The brick has more mass.
  • What do the particles do when a pot of water is being boiled on the stove?
    They spread out.
  • Find the volume of a cube that is 10cm wide.
    L x H x W 10 x 10 x 10 = 1000 CM3
  • The science tool used to measure the volume of a liquid or an irregular shaped object.
    Graduated Cylinder
  • True or False: When finding the mass of a beaker of water you use a graduated cylinder?
    False. When finding the mass of a beaker of water you use a balance.
