2 ) Construct explanations from observations that objects can be seen only when light is available to illuminate them (e.g., moon being illuminated by the sun, colors and patterns in a kaleidoscope being illuminated when held toward a light).

[SC2015] (1) 3 :

3 ) Investigate materials to determine which types allow light to pass through (e.g., transparent materials such as clear plastic wrap), allow only partial light to pass through (e.g., translucent materials such as wax paper), block light (e.g., opaque materials such as construction paper), or reflect light (e.g., shiny materials such as aluminum foil).

[SC2015] (4) 2 :

2 ) Plan and carry out investigations that explain transference of energy from place to place by sound, light, heat, and electric currents.

a. Provide evidence that heat can be produced in many ways (e.g., rubbing hands together, burning leaves) and can move from one object to another by conduction.

b. Demonstrate that different objects can absorb, reflect, and/or conduct energy.

c. Demonstrate that electric circuits require a complete loop through which an electric current can pass.

[SC2015] (4) 8 :

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

[SC2015] PS8 (8) 18 :

18 ) Use models to demonstrate how light and sound waves differ in how they are absorbed, reflected, and transmitted through different types of media.

Light is a very important energy source that keeps us warm and lets us see the world. Light travels in waves in bundles of energy called photons. Those photons contain all seven colors in the rainbow. Grab a prism and check them out!

The classroom resource provides a video that describes light, how it moves, and how it helps us see. This resource can provide background information for students before they construct their own models and carry out their own investigations. There is also a short test that can be used to assess students' understanding.

Light always travels in a straight line until something gets in its way. When that happens, light can be absorbed, reflected (bounced off), or refracted (bent), depending on what kind of surface it hits.

The classroom resource provides a video that will explain how light can move on and through different surfaces. This resource can provide background information for students before they create their own models or conduct their own investigations. There is also a short test that can be used to assess students' understanding.

Light is energy and color is a part of the light. In this video, students will learn more about how light behaves and why we see red.

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

In this media-rich lesson, students conduct simple experiments to investigate how light travels. They examine the paths that light takes with different materials and observe shadows, reflection, and refraction.

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.

This classroom resource provides a video that will describe the parts of the eye and how they work to allow sight. After utilizing this resource, the students can complete the short test to assess their understanding. This resource will provide background information to students before they create their own models.
