Describing Matter With Real World Applications







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.
