Properties of Light Scoring Guide - compacted as a NARRATIVE and in TABLE form

Beginning: Student demonstrates by explaining or drawing a picture that shows light will bounce off a mirror, light will change direction when it goes from one substance to another, and visible light can make different colors (by shinning on different colored objects).

ProgressingStudent demonstrates by explaining or drawing a picture that shows light can be made to bounce off a mirror at different angles, light will bend when it passes through different substances, and visible light makes objects different colors by reflecting the color of the object.

ProficientStudent demonstrates by explaining or drawing a picture that the angle of incidence is equal to the angle of reflection, the refraction of light depends on the density of the substance it travels through, that the color of an object is created from the reflection of that color and the absorption of all other colors, and white light is composed of all colors and will separate into different colors by refraction.

Student demonstrates by explaining or drawing a picture -

that shows light bouncing off a mirror.

Student demonstrates by explaining or drawing a picture -

showing light will change direction when it goes from one substance to another.

Student demonstrates by explaining or drawing a picture -

showing visible light can make different colors (by shinning on different colored objects).

2

Student demonstrates by explaining or drawing a picture -

shows light can be made to bounce off a mirror at different angles.

Student demonstrates by explaining or drawing a picture -

visible light makes objects different colors by reflecting the color of the object.

Student demonstrates by explaining or drawing a picture -

light will bend when it passes through different substances.

3

Student demonstrates by explaining or drawing a picture -

that the angle of incidence is equal to the angle of reflection

The color of an object is created from the reflection of that color and the absorption of all other colors. Because white light is composed of all colors and will separate into different colors by refraction.

The refraction of light depends on the density of the substance it travels through.
