Rock On!
Fifth graders built working loud speakers out of recycled materials. They studied the relationships between electricity and magnetism and learned how speakers work. Using the Engineering Design Process, they then designed, built, and tested their speakers. When talking to 5th grader Finn, he said, "My favorite part was figuring out how to make the speaker. My group came up with a few designs. We had some difficulties with the suspension system because the cone was not straight, but after a few tweeks we got the speaker to make sound." ROCK ON 5th Grade!
