Refraction: Converging Lenses
Refraction: Converging Lenses

Students investigate images formed by converging lenses using the Light Box & Optical Set, and discover the Focal Point. Download Teacher Notes and Student Worksheets Required Equipment

Index of Refraction
Index of Refraction

The semicircular block is ideal for a first quantitative activity on refraction. When placed as in this activity, rays bend only when exiting the block, simplifying observations. Students will measure angles of incidence and refraction, and calculate the index of...

Images Produced by Curved Mirrors
Images Produced by Curved Mirrors

Students use the Light Box and Optical Set's two different curved mirrors to investigate how light reflects from concave mirrors. Students make predictions and observations, and make generalizations about the focal point of a mirror, depending on its curvature. Download...

Color Addition
Color Addition

Students use the Light Box and Optical Set to observe the results of combining beams of colored light. Concepts include primary and secondary color addition and complementary colors. Download Teacher Notes and Student Worksheets Required Equipment Acknowledgements: Thank you to...
