SC15.1.3

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).

Planning and Carrying out Investigations

Crosscutting Concepts

Cause and Effect

Knowledge

Students know:
  • Some materials allow all light to pass through.
  • Some materials allow partial light to pass through.
  • Some materials block all the light from passing through.
  • Some materials reflect light, which changes its direction.

Skills

Students are able to:
  • Investigate to determine the effect of placing objects made of different materials in a beam of light.

Understanding

Students understand that:
  • Simple tests can gather evidence to determine that placing different materials in a beam of light will cause light to either: pass through, partially pass through, block, or reflect.
