Group: Emmy, Grace, Phoebe and Milly. Rube Goldberg machine

Our instruction was to create a machine that made a simple task but in a complicated way. The machine also needed to have 4 simple machines and 4 elements.I joined a group with Emmy, Phoebe and Milly. We planned out that we would flip a page in a book and throw some rubbish in the bin, but that our original idea.Our final point of the machine was to flip the page in the book and put the lid on the bin.

ObjectiveProject Description

Results

Emmy learnt about chain reactions and what they are.Phoebe understood how simple machine work and what they are(Same with me).Milly found out how to make a Rube Goldberg machine and what pulley are.

Marble roller and tube-Element 1I searched through my old toys and found the old marble roller from Grade 3. The marble roller is at the very start of the machine which the marble later goes through the tube.

Wedge and car-Element 2We never thought of this element because we originally used the catapult. For a long time we kept using the catapult hoping it would work but.. There were some technical difficulties. We finally had an idea of a new element(the wedge and the car) and removed the catapult.

Car and dominoes-Element 3Fortunately, this element was part of our original model, which was a relief of not having to change everything incase it backfired.

Pulley and bin-Element 4Mr. McKie supplied us with pulleys and Emmy brought in her Smiggle desk bin. This element is the last stage of the machine and the hardest part because we couldnt get the dominoes to release the string properly.(But we worked out what was going on after experimenting closely).
