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.
Convex lenses can project images onto a screen.
The image is only clear at a specific distance from the screen.
Convex lenses focus light.
