LIGHTS ON THE INTERNATIONAL SPACE STATION
 
Algebra 2

Key Topics: Power functions with negative exponents

The Lighting Environment Test Facility, or LETF, at NASA Johnson Space Center in Houston, Texas, investigates and evaluates proposed lighting systems for use on space vehicles. Lighting systems enhance the crew’s direct and indirect viewing ability during spaceflight. Students will perform a hands-on activity to explore the inverse relationship of illumination to distance. Students will then go on to calculate the number of lights needed in a module on the International Space Station.

Students will
  • analyze data from a simulation;
  • model data from a simulation using a graphical and algebraic approach; and
  • apply the measure of illumination, lux  =  Candela / m2 , to various situations.
