Science 4

In Grade 4 science, students will use a model of waves to describe wave patterns in terms of amplitude and wavelength. In addition, students develop understanding of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation. They will apply their knowledge of natural Earth processes to generate and compare multiple solutions to reduce the impacts of such processes on humans. In order to describe patterns of Earth’s features, students analyze and interpret data from maps. By developing a model, students will describe that an object can be seen when light reflected from its surface enters the eye.

Students will use evidence to construct an explanation of the relationship between the speed of an object and the energy of that object. Students also develop an understanding that energy can be transferred from place to place by sound, light, heat, and electric currents, or from object to object through collisions.
