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 solve problems relating to illumination on the International Space Station.

Instructional Ideas

• Provide a mini-lesson on the restriction of domains in order to model real-world situations

Classroom Considerations

• The hands-on activity requires flashlights, preferrably of different strengths
• Requires TI-Nspire handhelds

Pros

• The lesson provides a hands-on activity as a hook
• The TI-Nspire document also comes as a solution document for the teacher

Cons

• None
