2 Fails to Begin Effectively Directions not followed. Nearly all steps missing. Doesn t show understanding of how to develop experiment. They will calculate the percentage of air in sand using their volume measurements. They will see how the smaller the graduations on a measuring device increases its accuracy.
Volume is the amount of space something takes up.
It can be measured three ways. If an object is rectangular, the length, width and height can be measured with a metric ruler. The three numbers multiplied together are the volume in cubic centimeters. For irregularly shaped solids, water displacement can be used. The volume of a certain amount of water in a graduated cylinder or other measuring device is first measured.
