(3.5) Matter and Energy
Students explore physical materials and make observations about temperature, mass, magnetism, the abilities of objects to sink or float. They also develop the abilities to classify materials as solids, liquids or gases; to predict changes in materials caused by heating or cooling; and to create mixtures.
The student is expected to measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float.
The student is expected to describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container.
The student is expected to predict, observe, and record changes in the state of matter caused by heating or cooling.
The student is expected to explore and recognize that a mixture is created when two materials are combined such as gravel and sand, and metal and plastic paper clips.
