In this video from Curious George, students are engaged in a classroom activity that introduces them to volume. Using cubes, the students learn that volume is the amount of space that something takes up and that, no matter how they are configured, objects made using the same-sized parts will have the same volume.
The objects we encounter in our everyday lives have different physical properties. Many of these properties, including height and weight, can be measured using common tools. For example, to determine the height of a desk, you might use a tape measure or meter stick. To learn the weight of a phone book, you might place it on a bathroom scale.
Volume is another important physical property that we encounter in our everyday lives. To understand volume, you must first understand matter. Anything that exists is made of matter. Matter occupies space, and volume is the amount of space that matter occupies.
Depending on the shape of an object, measuring its volume can be straightforward or complicated. For objects with a regular shape, such as a phone book or a bowling ball, a simple formula can be applied to calculate volume. But for objects with an irregular shape, such as a pear or a paper clip, volume must be calculated in other ways. One method, called water displacement, involves placing an object in a marked container of water and measuring how much the object raises the water level when it is completely submerged. By knowing how much water is "displaced" by the object, you can determine how much space it takes up.
The volume of an object, like the various cube configurations featured in this video segment, is equal to the combined volume of its parts. That is, if ten cubes of the same size are attached to one another, then the volume of the assembled object—no matter what its overall shape—is equal to the sum of the volume of all ten cubes.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
