This is the front side to a two sided worksheet. This front page is to accompany a lesson about the history and transformation of music technology over the years. The back of the worksheet (separate download, also free on my page) is a planning sheet for the students to create the "next thing in music technology". This makes for an easy sub plan.
With this, I have my students write an advertisement for their own music technology that they've come up with. I do remind my students to solve one of the problems. Music technology changes over time to solve a problem, so if their product can solve one of those problems (space, time, connivence/ accessibility, etc.) I then have the students present their ads (on posters or sheet of paper) and have the class vote on what their favorite new invention was.
