Curated OER
Reflection and Refraction
Life is only a reflection of what we allow ourselves to see. The lesson includes three experiments on light reflection, light refraction, projection, lenses, and optical systems. Each experiment builds off the ones before and encourages...

Cylindrical Mirror
Using flexible mirror-like paper, physical scientists experiment with images produced by curving it and looking into its reflective surface. They find that concave mirrors cause reflected light waves to cross and actually flip the image...

Antigravity Mirror
Is it a bird? Is it a plane? It's super student! Physical science stars can fly during a unit on light as they see the reflection of one leg in a mirror, behind which the other holds them up.
Exploratorium
Corner Reflector
If you set up a triad of mirrors into a corner figuration, they act as a kaleidoscope, bouncing light waves back and forth indefinitely, changing the light that your eyes perceive. Although the materials required are very specific and...

Reflected Light
The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities.
Exploratorium
Parabolas
A parabolic mirror toy demonstrates how concave mirrors objects reflect light and produce a realistic image at their focal point. This resource probably doesn't explain any more than the printed insert that accompanies such an apparatus...
It's About Time
Curved Mirrors
Discover concave and convex mirrors using a laser light. Scholars experiment with real and virtual images before reading a handout and completing homework questions. Included extensions greatly benefit learners, so take advantage of the...

Science Activity 2: Light & Sound
Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...
Exploratorium
Touch the Spring
Concave mirrors and the images they produce are traditional topics in the physics classroom. This resource explains how to set up an investigation of them, and it provides you with the explanation of concepts.
Exploratorium
Hot Spot
Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.
Exploratorium
Polarized Sunglasses
Reflected waves of light move within a plane, and because of this, polarizing materials can reduce the glare our eyes see. This resource explains how to set up a demonstration of this effect. Consider it for use in your physical science...
Exploratorium
Vocal Visualizer
Make sound visible with an activity that provides directions for how to build a vocal visualizer meant to create light patterns. Making noise into the visualizer causes a mirror to vibrate, reflecting a laser beam, and creating the...
