Note: We are purposely using the terms “size” and “amount” instead of “volume” in discussions of density. We are also using “heavy”, “light”, and “weight” instead of “mass”. If your students have ...

Mass is the amount of matter in an object. Volume is how much space the object takes up ... I stop the class and we discuss the concept. Discuss density and have groups explain what is going on using ...

The density of an object or a substance is its mass, divided by its volume. We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. For example ...

record the mass accurately measure and observe the mass and the volume of the different objects use appropriate apparatus and methods to measure volume and mass and ...

It is always in three dimensions. To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³).
