The more different kinds of causes and effect, the better (potential energy, electricity, chemical reactions…). The students have to focus in the transfer of energy, problem solving, creativity and teamwork. On the final day, each group share their experience to the rest of the class.   Process: 1.- To introduce the lesson students view quick clip of Rube Goldberg device, for example the one below 2.- Make 4-5 students groups. 3.- Start thinking in the possible steps, energy transformations, materials etc. and draw the design drafts. Brainstorming. 4.- Do a list with all the material you will need, and how are you going to organize. The students can bring items from home to create the Rube Goldberg machine such as paper towel tubes, ping-pong balls, dominoes, matchbox cars, marbles etc. 5.- Contrast the design to the teacher, including size dimensions. 6.- Build the machine, and meanwhile document all the process: the problems to follow the design, the solutions to the problems, how are you measuring all the energy transformations for the document etc. 7.- Display their Rube Goldberg machine to the class during the last 10 minutes or so of class.
