i have to make a Rube Goldberg project for my science class.
( if u dont know what it is click http://www.youtube.com/watch?v=DtVkzgKObv0
note: the video above is far more then i need, below are deatails from the sheet we recieved.
your rube goldberg machine could do one of the following:
- begin by droping a marble into the machine and end it having the marble ring a bell
- begin by droping a marble into the machine and end by burstin an inflated ballon
- begin by dropping a marble into the machine and end by squeezing toothpase out of a tube.
you may choose a diferent talk but have it aproved by teacher.
Your machine needs to include a minimum of 5 different steps from start to finish, each step utilizing some principal of physics ( newtons laws, simple machines) it needs to be small enough to fit in the class room.(and prob bus. i dont get driven) the task should be completed in less than 3 minutes.
you MAY NOT use flames, chemicals etc. do not include offencive material or themes. no electric, live animals, or electronic equipment.
your machine should be constructed from materials you scrouge from home. the total cost for your machine should not exceed $5-$10. you should plan to put the pieces toghter with nails, screws, brackets, wood glue,or hot glue; not tape. the final product should be sturdy and transportable. possible materials: rubber bands, paper towel rolls, mouse traps(spring kind) rulers with grooves, parts of old toys, parts of plastic milk jus, soda bottles, straws, popsicle sticks, scraps of wood, foam board, bottle caps, etc.
any ideas of a simple yet good idea?
