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 a Light Probe to measure how much light is blocked by layers of the different materials.


In this activity, you will

  • 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.
