Research the origin of the metric system to discover how the kilogram was first defined and what other units of mass it replaced. The air in your classroom has a density of about 0.001 grams per cubic centimeter (0.001 g/cm3) (Figure2.8). This means there is a new (or improved) theory waiting to be discovered that can explain the new evidence (as well as all the old evidence).30 UNIT 1 THE PHYSICAL SCIENCES A car has more mass than a bicycle because the car contains more matter.

Explain, using numbered steps, how you could find the volume of a small, irregularly shapedrock. Measuring the You can measure the volume of liquids by pouring them into a graduated volume of liquids cylinder. TPT empowers educators to teach at their best. The way people came to understand the solar system is a good example of how new evidence leads to new and better theories (Figure 2.5).32 UNIT 1 THE PHYSICAL SCIENCES 2.1 Measuring Mass and Volume 33 Like this book? How do you get distance from speed and time and time? The density of a liquid is lower because the atoms are not packed as tightly as in a solid. He puts a thermometer in a pot of boiling water and observes that the water cools off once its removed from the heat source.
