Analyze and interpret data from observations to compare how light behaves when it shines on different materials.
- Physical Science: Exploring Light and Shadows
The student will demonstrate an understanding of the properties of light and how shadows are formed.
Objects can only be seen when light shines on them. Some materials allow light to pass through them; others allow only some light to pass through; and some do not allow any light to pass through and will create a shadow of the object. Technology such as mirrors can change the direction of a beam of light.
