OBJECTIVES: comparing reflect and refract. Discovering exactly how light moves VOCABULARY:

 lens reflect refract MATERIALS: winter prism lens glass that water or various other objects the light can go with flashlights Swift GH microscopic lense or other reflecting light microscope

Students watch at different items and also determine if lock reflect or refract light

BACKGROUND:

The world is full of images for children. A enjoy in a mirror or home window can scare them; a penny in a pool might look closer 보다 it yes, really is. Irradiate has constantly played with our sense of sight. Youngsters can learn how these photos are various from the actual thing. Children need to uncover that lock can change the method light moves. As children play with optic toys, they start to see that light deserve to play tricks v their eyes.

You are watching: What is the angle of reflection degrees

Young kids need to experience various examples the reflect and also refract to recognize them easily. Reflect is simpler to know than refract. Enjoy is simply a "bouncing" ago of one image, when refraction is a change of direction of an image. A prism, for example refracts or bends light to create a rainbow.

However, with just a small guidance, students have the right to look at light and also identify whether it refracts or reflects. PROCEDURE:

In this lab, students will "play" with light. Student will see several instances of reflection and refraction and will try to find how light moves.

screen different varieties of objects that reflect and also refract. Common objects include mirrors (reflect); glass of water through spoon in that (refract); foil (reflect); oil in a glass party (refract); prism (refract); glass (refract); lens (refract); or any type of shiny surface (reflect). Instruct students come shine light with the various objects and also have them record on their lab sheet whether the irradiate is refracted or reflected. Instruct castle to create in the object and then words "reflect" or "refract." Students must look in ~ the Swift GH and also then look with the optic tube. The irradiate is refracting v the tube. Ask the students exactly how they can get much more light with the objective. Give them words "mirror" as a clue. The winter can help concentrate light v "reflection" and also then assist to illuminate things better. The Swift GH provides reflected light. The irradiate bounces increase from the object with the lens in the objective. The light climate is refracted with a series of lenses.

Then you view the image through the eyepiece.
