The concepts of refraction and reflection gel with your physical science class during this colorful exploration. Shining lasers through Petri-dish-shaped gelatin desserts, they will notice how the light travels and bounces off the sides....

Very simply, geometers examine a pair of rectangles on graph paper and find a translation and rotation to demonstrate their congruence. A couple of questions follow to stimulate critical thinking about other possibilities.

The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another. 

Introduce your earth science enthusiasts to the earth's energy budget. Teach them using an informative set of slides that include illuminating lecturer's notes, relevant vocabulary, embedded animations, colorful satellite maps, and a...

Ahoy, matey! Here is an engineering expedition that mini mariners are sure to be swept away by! After reading a brief description and history of periscopes, they work in crews to construct one. Use this activity to enhance a lesson on...

Reflection is the bouncing of waves. Reflection can be used simply as entertainment or to guide ocean navigators. As your physics aces begin learning about waves, this resource would be valuable to show them that all of the different...

This video gives a formal definition of odd and even functions, as well as, an intuitive feeling for how they are different. By looking at the graphs of both types of functions, Sal shows the reflection properties of both functions....

Beam me up, Bill! Explore how beams of light behave when they strike flat and curved surfaces. Bill bends light using a nifty contraption that streams three beams through a straight and a curved piece of plastic. He also defines and...

Nineteen word problems dealing with frequency, speed, reflection, and refraction of light are provided here. Empower your physics masters to manipulate equations for computing angles, focal lengths, image heights, and more! This is a...

Students design and construct a listening device that will allow them to listen to the sound generated by specific object inside a box.

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Geometric transformations are explored by high schoolers. They will create a set of instructions for plotting coordinates representing an original transformation of a real-world figure. These instructions are shared with middle...

Middle school science stars observe and record data on the solar radiation reflected off or transmitted through various materials. They predict properties for various materials, and test their predictions by touch. This lesson becomes...

Twelve pages of mostly multiple-choice questions comprise this comprehensive New York Regents physics exam. It covers an entire year's worth of physics curriculum and requires about three hours for completion. Review the questions to...

Students use prior knowledge of angle and lines as they conduct an experiment with a rolling marble to determine the shape of a mystery object located under a metal pie tin.

Young scientist explore the various positions in the debate on stem cell research and then discuss these perspectives before formulating their own positions. They must research the topic and beliefs that others have. They will also look...

Using M.C. Escher's Hand with Reflecting Sphere as inspiration, learners create their own set of self-portraits using various reflective surfaces. The lesson begins with a discussion about portraiture and ends with a presentation of work...

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.

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...

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

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...

When your life science class is learning about the eye and how it works, you can add this activity as a demonstration of how the retina holds an afterimage. After staring at a red, green, or blue bird shape, pupils glance at a cage and...

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...
