Properties of Objects and Materials
Objects have many observable properties, including size, weight, shape, color, temperature, and the ability to react with other substances. Those properties can be measured using tools, such as rulers, balances, and thermometers.
Position and Motion of Objects

The position of an object can be described by locating it relative to another object or the background.

An object's motion can be described by tracing and measuring its position over time.
The position and motion of objects can be changed by pushing or pulling. The size of the change is related to the strength of the push or pull.
