During the investigation for this week, students
measured the mass and volume of four objects and found the average of three
trials for each object. Students were able to find the volume
of a rectangular object by multiplying the object’s length by its width and
height and the volume of an irregular object by subtracting the volume of water
in a graduated cylinder without the object from the volume of the water with
the object. The mass was determined by
using a beam balance. Metric units of
measurement were used because of the International System of Measurement used
by scientists world wide.
Some of the real life conclusions the
students came up with after completing the investigation were that Doctors need
to know the mass of a patient before deciding how much of a medication to
prescribe because smaller patients
should receive less medicine. Scientists should use the same system of
measurements so that they can share information without having to convert their
results to another measurement system.
