A Critical Lab
Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...
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.
Curated OER
Focusing on Lenses
Young scholars explore scientific observations by examining the parts of a microscope. In this optics lesson plan, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a microscope....
Curated OER
Microscopes and Telescopes
Young scholars 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
Making a Periscope
Students experiment with a simple periscope to see how it reflects light. They draw a diagram of the path a ray of light follows as it travels from an object, through the periscope, and into your eye.
Curated OER
Pinhole Viewer
Pupils make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.
Curated OER
Cloud Shadows
Students classify the visual opacity of various materials, what is needed to create shadows, and classify clouds by the types of shadows that they produce.
