Science Processes and Inquiry

Physical Science

  • 1 The position of a moving object can be described relative to a stationary object or the background. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

  • 2 Energy is the ability to do work or to cause a change in matter. Forms of energy include electricity, heat (thermal), light and sound. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

    • 1 Electricity is the flow of electrical power or charge.

      • a The flow of electricity is controlled by open and closed circuits.

      • b Some materials are conductors of electricity while others are insulators.

    • 2 Heat results when substances burn, when certain kinds of materials rub against each other, and when electricity flows through wires.

    • 3 Light is a form of energy made of electromagnetic waves.

      • a Light waves travel in a straight line.

      • b Substances may cause light waves to change direction of travel (e.g., reflection, refraction).

      • c Sound is a form of energy caused by waves of vibrations that spread from its source.
