Three more labs to study convex and concave lenses. These labs require no setup and could be used in centers or stations. The directions are written directly to the students so you don't have to introduce them. 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 images appear different when viewed through convex vs. concave lenses?
- What type of lens can flip an image vertically or horizontally?
- What types of lenses are used in telescopes and why?
Once students try this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions.
- Both convex and concave lenses can change the size of an image.
- Convex lenses can flip the image vertically and horizontally.
- Concave lenses don’t flip images.
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 Convex and Concave Lenses, Whiteboard or Blackboard
