About this worksheet

What students practice

  • Students model light traveling from a source, bouncing off an object, and entering an eye.
  • Students use investigation results to explain how blocking different light paths affects sight.
  • Students predict whether an object will be visible when a light path changes.

How to use

Read the investigation together and trace the tested paths with a finger. Have students use the results to answer questions and draw a light-path model.

Curriculum

The Playground Puppet Light Test

Use test results to model how a puppet becomes visible.

1. Investigate the Puppet Stage

Read the investigation. Use the results to answer each question.

A Puppet Show Inside a Box

At the playground's puppet stage, Ms. Chen's class investigated what lets someone see a cloth puppet. An adult placed the puppet inside a large box. The puppet did not make its own light. A small opening had a soft eyecup that blocked daylight when a student looked inside. The box stayed closed during each test.

First, the class fixed a flashlight inside the box, to the side of the puppet. It pointed at the puppet, not toward the viewing opening. Next, students marked two places for a sheet. Place A was between the flashlight and the puppet. Place B was between the puppet and the viewing opening. A sheet at either place did not touch the puppet.

Then the class ran five tests in order. They changed whether the flashlight was on and whether a sheet was at A or B. They kept the puppet, flashlight, and viewing opening in the same positions. The same student looked through the opening each time. Students recorded whether the puppet was visible, meaning the student could see its shape.

Test 1: Flashlight off; no sheet. The puppet was not visible.
Test 2: Flashlight on; no sheet. The puppet was visible.
Test 3: Flashlight on; opaque card at A. The puppet was not visible.
Test 4: Flashlight on; opaque card at B. The puppet was not visible.
Test 5: Flashlight on; clear sheet at B. The puppet was visible.

The opaque card did not let light pass through it. The clear sheet let light pass through. The two sheets were the same size and covered the same area when placed at B. Before each test, students checked the sheet's position and the flashlight switch. Afterward, they planned models using arrows to show the direction light traveled. Their models needed to explain both the visible and the hidden puppet.

1.
Compare Tests 1 and 2. Which claim does this comparison support?
  • A. The viewing opening became larger when the light was on.
  • B. Light from the flashlight helped make the puppet visible.
  • C. The puppet made its own light when the flashlight was off.
  • D. The viewer moved closer when the flashlight was on.
