7. Your Challenge Today?

8. Making a Speaker

9. Making a Speaker...with Plates =

10. Your Materials Plates (styrofoam, paper), Bowls (styrofoam), and Cups (styrofoam) Masking Tape 2 Neodymium Magnets (½” diameter x ½” height) 1 Neodymium Magnet (½” diameter x ⅛” height) Magnet Wire (32 gauge) Index card Ruler Scissors AAA Battery Instruction Manual created by ExCITe Center MET-Lab

11. Your Goals 1.Build a speaker that can play sound from an MP3 player when connected to an amplifier. 1.Refine and redesign the speaker to improve volume, clarity, and range of sounds produced. 1.Communicate your process and progress to judges.

12. Please Consider Safety When you touch the battery to the wire for testing, be aware that heat may be given off. The magnets are VERY powerful. ●Keep away from credit cards and electronic devices. ●Try not to get pinched when magnets snap together. ●Magnets may shatter if they snap together quickly.
