The students had the opportunity to extend their knowledge of simple machines by building Rube Goldberg machines that could solve a problem they face in their lives. Machines solved problems such as: turning an alarm clock off, turning the light on without getting out of bed, opening and closing a garage door, feeding a dog, feeding a fish, putting toothpaste on a toothbrush, and closing a blind. Students presented their projects to the class. They had the choice of presenting their machines live, creating a video and showing it to their class or a hybrid of both where students videoed their machine, but then explained to the class what was happening in the video. I have attached three of the videos to this blog entry.Two of the videos feature music by Julian Smith, a new YouTube sensation.
In this lesson students used 21st century presentations skills as well as various technology skills to create their videos. I could improve this lesson by allowing students to keep a class blog which would allow them to collaborate on their project, swap ideas and constructively criticize each others’ work before the presentation day.
