Convex lenses can make real images on a screen. It's almost magical to watch in this day where screens are ubiquitous. This is a simple and easy experiment to for kids to start or continue a study of light and optics. Kids will be intrigued by the phenomenon and want to dig into the concepts. Activity includes a one-page reading that can be used as a read aloud or student reading or teacher read-aloud. Reading includes questions and 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 to the image as you move a lens toward a screen?

  • What happens to the image as you move a lens away from a screen?

  • What does it mean for lenses to have a focal point?

 

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

 

Concepts Addressed

  • Convex lenses can project images onto a screen.

  • The image is only clear at a specific distance from the screen.
