Lights on the International Space Station
Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Power, Work and the Waterwheel
Students use a two-liter bottle, dowel rod and index cards to design and construct a water wheel. They then calculate the power created and measure the work done by the water wheel in Watts and Joules.
