If you're looking for a fascinating and simple start to your study of optics and lenses, consider pinholes. They're are a great way to start your optics investigations. If you've never studied pinholes you're in for a treat! With a bit of foil and a desk lamp you can make pictures on a screen. Kids are fascinated by this phenomenon and happy to explore over and over. Pinholes act like convex lenses. Activity includes a one-page reading that can be used as a student reading or teacher read-aloud. Reading includes questions and sample answers. Also included are 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 happens when you put a pinhole in front of a bright scene? 
  • What will a pinhole show when placed in front of a screen? 
  • How can you set up a pinhole to show a scene?

 

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. 
  • Lamps radiate or give off light.
