     These students are learning to use a graduated cylinder.  They've learned to look for the bottom of the meniscus to measure accurately.  And they are learning how metric units of measurement are related.
     They learned that one milliliter equals a cubic centimeter.  They also learned that 1000 milliliters equals a liter (just like 1000 millimeters equal a meter).
     During this lesson, they measured 20 milliliters of water in the graduated cylinders, predicted the mass of the water, and then checked their predictions with a balance.
     After learning to use their graduated cylinders, they were challenged to use them to determine the volume of an irregularly shaped solid (a large metal screw).   This can be done by displacing water, but they needed to figure out that trick.
