During
the week of December 5 West Middle School seventh-grade science classes were
learning about volume. Volume of regular objects is found by this
equation: length x height x width. The unit of measurement for solid
objects is centimeters cubed. For a liquid, the unit of measurement
is mL.
During
a hands-on lab activity the students found the volume of a solid irregular
object by using the method of water displacement. They put objects such as a
screw, a nut, and or/a washer in a graduated cylinder, filled to a specific amount
with water. Then they observed how much the water rose. The difference in these
two measurements was the volume of the solid irregular object.
From
our lab the students now know that volume and weight are very different. Also
the greater the weight does not always mean the object will have a greater
volume. This lab demonstrated one of our many science curriculum objectives.
