You have been asked by the ACME shirt company to design a shirt that will block the most light for the company’s new “Sunblocker” line of shirts. They have given you several fabrics to test. Use Go Direct Light and Color to measure how much light is blocked by layers of the different materials.


  • Measure the light intensity as it passes through layers of different kinds of fabrics.
  • Predict which fabric will block the most light.
  • Draw conclusions about which fabric would be best for a shirt.
