In this lab students dig into convex lenses and see how they flip the image depending on how you hold them. It's a good lab for deepening skills and requires no setup, yay! If you're studying light and optics with your students, this is a quick and simple lab and could even be set up as a center or station. 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:
- How do objects look when viewed through a convex lens?
- How do objects appear to change according to the position of the convex lens?
- When does an image appear upright when viewed through a convex lens?
Once students try this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions.
Concepts Addressed
- When a convex lens is held near an object the image is always upright.
- Convex lenses converge or focus light.
- The image you see through a convex lens depends on its location relative to its focal point.
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.
