About this worksheet

What students practice

  • Students model light traveling from a source to an object and then into an eye.
  • Students use investigation evidence to explain how barriers change whether an object is visible.
  • Students evaluate cause-and-effect claims about reflected light and seeing objects.

How to use

Read the festival investigation together, then have students use the trial records to build and check light-path models.

The Kite Festival Viewing Booth

1At the Kite Festival, Priya, Jonah, and Elena built a small viewing booth. A battery-powered lamp shone toward a shiny silver patch on a kite. The patch did not make its own light. A visitor looked through a narrow opening at the patch. The students marked two places where an opaque card could be held: A was between the lamp and the patch, and B was between the patch and the visitor's eye.

2The students began with the lamp on, the silver patch in place, and both openings clear. In Trial 1, the visitor saw the patch. In Trial 2, they turned the lamp off but changed nothing else. The visitor did not see the patch. In Trial 3, the lamp was on, but an opaque card was held at A. The visitor did not see the patch.

3In Trial 4, the lamp was on and the card at A was removed. A different opaque card was held at B. The visitor did not see the patch. For Trial 5, the students replaced the card at B with a clear plastic sheet. The lamp, patch, and visitor stayed in the same places. The visitor saw the patch.

4The students made two more changes one at a time. In Trial 6, the lamp was turned so its beam missed the silver patch. The visitor did not see the patch. In Trial 7, the lamp still lit the patch, but the patch was tilted so the bright reflected beam went toward a side opening instead of the visitor's opening. The visitor at the front opening did not see the bright patch.
