Lesson

• Program
  • Volume is the measurement of how much total space an object fills.
  • For a "regular" shaped object, you can multiply length, times width, times height.
    • Take a box or cube and make the linear measurements (with a ruler) to determine the volume of the object.
  • Look at a stone and see if it can be measured in the same manner with a ruler. (Probably not)
  • Look at the graduated cylinders. Compare the 4 Liter ones and see if their capacity is the same regardless of the shape of it (they should be).
  • Depending on the size of your object, choose the appropriate cylinder to hold your object.
  • Fill the cylinder partially full of water and mark the level. Now gently lower your object into the water and note the new water line. Subtract the original measurement from the current one and you will have the volume of the object.
  • Now take a small, but regularly shaped object and find the volume with the linear measurement. Next put it into the graduated cylinder and find its liquid volume. How do they compare?
  • Try measuring the volume of a solid object and one of similar measurement, but hollow. How does their volume compare? In the metric system, the number should be the same, even though the units may change. 1 cubic cm = 1 ml = 1 gm (That is one of the reasons the metric system has been so widely used throughout the world.)
