Science consultant and retired teacher Brian Wallrapp engaged fourth-grade students at Winthrop Avenue in numerous experiments that demonstrated the forces of magnetism, static electricity and electromagnetism. The dynamic class reviewed science principles taught in class and helped to prepare students for state testing this spring in a fun-filled and informative way.
Mr. Wallrapp, also known as “Magnet Man,” taught the students that all matter is made of atoms and discussed where electricity comes from, how magnets repel and attract, and how the human body can conduct electricity. To demonstrate static electricity, the students rubbed a balloon on each other’s hair and used the charged balloon to lift salt. They also formed a human circuit to light a bulb and learned how a plasma globe transfers energy from one location inside the glass to another.
