BIKES: Science on Two Wheels

Presented by:

With support from:


Centripetal Force Seat – Take a seat on a rotating stool, spin a hand-held bicycle tire, and see how the rotational forces move them as they turn the tire from a vertical to a horizontal position.

Gear Box Box – Discover why more gears equal less work for the rider! Lift one of four sets of bowling balls, which demonstrates the energy transfer of gears.

Gear Table – Experiment with magnetic gears.

Roller Ramps – Roll a wheel down a series of ramps – each with a different sloping, but with the same height drop – to see Newton’s Laws in effect.

Helmet Aerodynamics – Watch three shapes race through pearlized fluid to see which shape’s design is the most aerodynamic, as it relates to helmet design.

Coatings/Color Match – Try to identify ‘stop sign red’ from a set of 9 samples and learn how the brain recalls color.

Color Mixing Bike – See how the eye perceives color and how colors in the visible spectrum work. Change the ratio of three colored lights to change the apparent color of some miniature bikes.

Tire Treads – Make your own tread rubbings and explore tire variations in sports and terrain.

Hit the Brakes! – Put on the brakes on a spinning disk, using three different pads to see how materials affect friction.

Bike Body Xylophone – Play a series of tubes, made with different materials, to discover why bikes can be made from so many alloys.

Carbon/Steel Scales – Observe two ‘identical’ bikes hanging from two meat scales to see that one is a fraction of the weight of the other, due to its space-age carbon fiber construction.

Bike Seat Bench – Take a seat on a bench topped with a variety of bike seats as you explore design and materials.

Seat Wall – Tour a grid of seats from the 1800s to present day and discover the development of materials from leather to plastics to the most modern fabrics and foams.
