Grade 4 > Physical SciencesEnergy4.PS3.1 Use evidence to construct an explanation relating the speed of an object to the energy of that object. 4.PS3.2 Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents. 4.PS3.3 Ask questions and predict outcomes about the changes in energy that occur when objects collide. 4.PS3.4 Apply scientific ideas to design, test, and refine a device that converts energy from one form to another. Waves and their Applications in Technologies for Information Transfer4.PS4.1 Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move. 4.PS4.2 Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen. 4.PS4.3 Generate and compare multiple solutions that use patterns to transfer information. |
