SC.4.2 Waves: Waves and Information

  • SC.4.2.1 Gather, analyze, and communicate evidence of waves and the information they transfer.

    • SC.4.2.1.A Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

    • SC.4.2.1.B Generate and compare multiple solutions that use patterns to transfer information.

SC.4.4 Energy: Conservation and Transfer

  • SC.4.4.2 Gather, analyze and communicate evidence of energy conservation and transfer.

    • SC.4.4.2.A Use evidence to construct an explanation relating the speed of an object to the energy of that object.

    • SC.4.4.2.B Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electrical currents.

    • SC.4.4.2.C Ask questions and predict outcomes about the changes in energy that occur when objects collide.

    • SC.4.4.2.D Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

    • SC.4.4.2.E Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

    • SC.4.4.2.F Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment.

SC.4.6 Structure, Function, and Information Processing

SC.4.13 Earth's Systems: Processes That Shape the Earth
