Product Description

Build a simple pinhole projector to study optics. This is a great precursor to understanding lenses. Then, while you're still outside, go on a pinhole walk looking for natural pinholes--you'll see them everywhere once you know how to find them.

The directions are written directly to the students so you don't have to introduce them. This is a great addition to a study of light and optics. The lab includes cards for Claim, Evidence, and Reasoning (CER) that can be used in a variety of ways.

Use this to learn and reinforce answers to questions such as:

  • What does a shaped pinhole show when it’s held near a screen?
  • How can trees make perfectly round circles of light on the ground?

Once students try this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions. 

Concepts Addressed

  • Light coming from objects can be projected onto a screen.
  • A pinhole will cast an image of whatever is behind it.

Answer Keys and Teacher Notes address most questions and issues that might arise in this study—you shouldn’t have to do any outside research unless you want to.

Materials Needed Foil, Pushpin, Thin cardboard, White cardboard screen, Scissors, Tape.

Prep Needed Gather supplies.


Teaching Time   30 min or more depending on writing assignments and whether you take the pinhole walk.
