Overview:

The Sun is a natural source of visible light waves. Our eyes see the reflection of the sunlight off the objects around us. Check out the simulation to learn more about scattering light.

Content Standard(s):

Science
SC2015 (2015)
Grade: 4

8 ) Construct a model to explain that an object can be seen when light reflected from its surface enters the eyes.

NAEP Framework

NAEP Statement::
P4.2: Objects vary in the extent to which they absorb and reflect light and conduct heat (thermal energy) and electricity.

NAEP Statement::
P4.9: Light travels in straight lines. When light strikes substances and objects through which it cannot pass, shadows result. When light travels obliquely from one substance to another (air and water), it changes direction.

Scientific And Engineering Practices:

Developing and Using Models

Crosscutting Concepts: Cause and Effect

Disciplinary Core Idea: Waves and Their Applications in Technologies for Information Transfer

Evidence Of Student Attainment:

Students:

Construct a model and use it to explain that in order to see objects that do not produce their own light, light must reflect off the object and into the eye.

Teacher Vocabulary:

reflection
opaque
translucent
transparent
refraction

Knowledge:

Students know:

Light enters the eye, allowing objects to be seen.
Light reflects off of objects, and then can travel and enter the eye.
Objects can be seen only if light follows a path between a light source, the object, and the eye.

Skills:

Students are able to:

Construct a model to make sense of a phenomenon.
Identify relevant components of the model including: light (including the light source), objects, the path that light follows, and the eye.

Understanding:

Students understand that:

An object can be seen when light reflected from its surface enters the eyes.
