Students learn how electric charges affect objects and how electric current moves through a closed circuit.
Students learn how electric current flows through series circuits and parallel circuits.
Students also learn rules for using electricity safely. Students learn how magnets act and how the earth is like a magnet. By the end of fourth grade, students will develop an understanding of light, heat, electricity, and magnetism. Students construct a series and parallel circuit that will light a bulb. Students manipulate a variety of magnets to determine polarity and their characteristics.
