Have you ever been in a swimming pool and seen someone in the water look cut off at the surface of the water? What you are seeing is due to refraction. When light bends through something, such as water, it is called refraction. And, that is what is happening when we look at our reflection in the mirror - light is bouncing back at us from the mirror. What do you call it when light bounces off something? It is called reflection. Light is amazing! It is a form of energy that can bend and bounce, and it comes in all different colors.

piece of plastic polarized film (purchase at a hardware store)Ĭopyright © College Physics.

Dispersion Angle through a Prism (visual aid).

1 light source (such as: overhead projector, slide projector, sunlight through opening in window shades, flashlight).

1-5 prisms (can be assorted sizes) (available in science supply catalogs or websites, or hobby stores).

1 plastic ruler or pencil or popsicle stick (or any straight object that can get wet).

1 clear plastic bowl (deep enough to show refraction).

The total cost for four stations is ~$20. The materials at each station are re-usable for an unlimited number of teams.

slinky (optional demonstration see Introduction/Motivation section).

The currents may have been produced to begin with by transforming the energy of motion into electrical energy.Įnergy can be transferred in various ways and between objects. In such collisions, some energy is typically also transferred to the surrounding air as a result, the air gets heated and sound is produced.Īlignment agreement: Thanks for your feedback! Light also transfers energy from place to place.Īlignment agreement: Thanks for your feedback! Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. When objects collide, energy can be transferred from one object to another, thereby changing their motion.

Make observations to produce data to serve as the basis for evidence for an explanation of a phenomenon or test a design solution.Īlignment agreement: Thanks for your feedback!Įnergy can be moved from place to place by moving objects or through sound, light, or electric currents.Īlignment agreement: Thanks for your feedback! Energy is present whenever there are moving objects, sound, light, or heat. This activity focuses on the following Three Dimensional Learning aspects of NGSS: Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.Ĭlick to view other curriculum aligned to this Performance Expectation

For example, we wear sunscreen and sunglasses to protect our skin and eyes from ultraviolet waves. Explain that there are also waves that cannot be seen by the human eye that affect our daily lives.Understand that a prism sorts a light beam into its various wavelengths, appearing as a rainbow of colored light.

Understand that light is made up of waves, and that waves at different wavelengths create different colors.Understand the phenomenon of refraction - that when light travels across the border of two transparent media (such as air, glass, Lucite, etc.), the path of light bends.By understanding polarized light, engineers have created laser applications, electron microscope imaging and medical imaging techniques, in addition to sunglasses and camera filters that reduce the glare from the sun.Īfter this activity, students should be able to: Engineers also use their knowledge of light energy, lenses and prisms as they design eye glasses, binoculars, cameras, medical equipment, satellites, optics and lasers.

Civil and structural engineers study light properties to determine the optimum type of windows to install in a building. Įngineers apply their knowledge of the properties of light and light energy to the creation of many useful products and tools.
