Speaker Lesson

In this activity, we build a speaker from a styrofoam cup a couple of magnets and speaker wire. It's amazingly easy to do and the sound is really good (though the volume is a bit quiet). I will include my instructions for the students and a copy of the original article where I got the idea and plans from (as well as a list of the materials needed).

Here is a link to the article it comes from:
