Scribbling machines are motorized contraptions that move in unusual ways and leave a mark to trace their paths. They are made from simple materials and set in motion by a vibrating offset motor causing them to bounce, spin, bump and move in interesting ways
Students will construct a bridge to span a minimum distance of 30 cm with no supporting pillars in between the ends of the span. It needs to be strong enough to support 4 smartphones in the centre of the bridge at the same time.
Students become product engineers in a bouncy ball factory as they design and prototype a polymer bouncy ball that meets specific requirements: must be spherical in shape, cannot disintegrate when thrown on the ground, and, of course, must bounce.
How does mass affect momentum in a head-on collision? Students explore this question and experience the open-ended engineering design process as if they are the next-generation engineers working on the next big safety feature for passenger vehicles.
For this maker challenge, students decide on specific design requirements (such as good traction or deep cushioning), sketch their plans, and then use a variety of materials to build prototype shoes that meet the design criteria.
Students are challenged to design their own small-sized prototype light sculptures to light up a hypothetical courtyard. To accomplish this, they use Arduino microcontrollers as the “brains” of the projects and control light displays composed of numerous (3+) light-emitting diodes (LEDs).
