Rube Goldberg...um, who's that? He didn't exist when I was in school. For some reason I am the only person in the world who didn't understand what a Rube Goldberg project was. Time to learn. Maddie had to create a "functional Rube Goldberg invention". In other words, it had to "do" something. It also had to have at least 5 components. So, here it is...
The train was the force (wheel and axle). It pulled a string that went through a bobbin (pulley). The string the pulled our pen (wedge). When the wedge moved, the tape rolled down the incline (book) which was on a wedge (wedge #2 that is). Tape rolled down incline into the dominoes (dominoes). Dominoes hit the mouse trap (2nd class lever). Mouse trap launched the ball over the net to the other side and Maddie hit it back! Complete, totally awesome and done!
School has gotten so much more complicated!
