Continue a study of convex and concave lenses seeing how they're alike and different. Which can make real images, which can cast a shadow? These 3 labs will make a great addition to your study of light and optics. Each lab includes cards for Claim, Evidence, and Reasoning (CER) that can be used in a variety of ways. Each of the three labs is complete in itself and is an extension of the concepts first taught in the activity 

 

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

  • How do convex and concave lenses differ?
  • What type of lens casts a shadow?
  • What types of lenses are converging and what does that mean?

 

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

 

Concepts Addressed

  • Only convex lenses can make real images (cast onto a screen).
  • Focused images occur only at specific distances.
  • Pinholes can act like convex lenses.
