Fourth grade students use investigations to learn about the natural world. While studying physical science, students learn about matter, and how to compare, contrast and measure changes in physical materials. They also explore force and motion, and investigate different forms of energy.
By fourth grade, students are ready to learn that energy exists in many forms, including mechanical, sound, electrical, light, and heat/thermal. They begin in-depth explorations of electricity, such as building electrical circuits, and they learn about conductors and insulators. Students also design an experiment to test the effect of a force on an object.
