Welcome to March!
After a much needed break students came back to school and amazed me with the work on their Rube Goldberg machines. Everyone showed a great deal of care in researching,planning, hypothesizing, experimenting, and reporting on their outrageous machines! Some featured elements include:
A lift launch of the marble raised by a string attached to a lever
A marble catapulted into a funnel aimed with accuracy and precision by clay of a particular mass, dropped from exactly 17 inches
A ramp supported by a trio of tripods with stable bases and a reasonably secure center of gravity
The potential energy of a powerful spring launch which was super kinetic!
A marble whose exact roll around curves was managed by counterweights and stopped by magnetic attraction
A precise and powerful ball bearing shot which rang a bell whose sound energy would normally be muffled by carpet
A marble launched on a buoyant aluminum boat powered by the wind energy from a fan
A marble buoyed downstream on a waterfall, which rattled an aluminum tunnel which rang the bell twice
A marble which rang a bell and was stopped in its track by its mass piercing the surface tension of a pool of water and sinking
A marble whose direction was beautifully controlled by guide rails and friction, which rang a hand made plastic bell
A perfect strike which knocked bowling pins off of their center, and rang the bell
And SO ON!!!!! Great job everyone!!!!!!!!!!
