The L.O.S.T. Art of Image Description - Converging Lenses
Magnifying glasses and cameras often use converging lenses, but how do they alter an image? Pupils discover a lens, axis, and object arrow before identifying four characteristics of the resulting image. They label the location,...

Optics: Mirrors and Lenses
Did you see that or did I imagine it? Optical illusions are often created with mirrors and lenses, and here is a presentation that covers many different types of mirrors and lenses and how they work. Flat, concave, and convex mirrors, as...

Physics Midterm Exam #3 - Electromagnetic Radiation
True-false and multiple-choice questions are posed in Part A of this exam, covering the topic of electromagnetic radiation. In Part B, problems relating to refraction must be solved. This is a well-rounded exam that will help you...
Curated OER
Mirrors and Lenses
Students identify the characteristics of mirrors and lenses. In groups, they describe the types of images formed by converging and diverging mirrors and calculate the magnification of a spherical mirror. They follow the same procedure...
Curated OER
Light and Optics
Students discover the relationship between lens shape and the formation of images in an experiment. They use three different size converging lenses and a diverging lens to calculate and compare the focal length of each. They graph and...

Building a Compound Light Microscope
What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...
Curated OER
Reflection, Refraction & Lenses
Students are able to describe what happens to light when it strikes different materials. They describe the law of reflection. Students are able to explain why a mirror froms a virtual image. They are able to describe diffuse reflection.

Microscopes and Telescopes
Students analyze a microscope and study what they do. In this investigative lesson students study how microscopes were first invented, and how ray diagrams are used in conjunction.
Curated OER
Pinhole Viewer
Students make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.
