Objects can be described by the properties of the materials from which they are made. Properties can be used to separate or sort a group of objects or materials.
Objects are made of one or more materials.
Materials can exist in different states – solid, liquid, and gas.
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.
Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
