A common experiment for studying the reflectivity of different colored surfaces makes use of colored construction paper, aluminum foil, a light source, and a light sensor. Voyager’s light sensor and the little flashlight included with the Explorer Kit are perfect tools for performing this experiment. Empty graphs and data tables suitable for copying for student use are included with this lesson.
NGSS Alignment: MS-PS2-3
MS-PS2-2: Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
The standard is broken down into the three NGSS pillars below:
Science and Engineering Practices - Developing and Using Models
Disciplinary Core Ideas - PS4.A Wave Properties and PS4.B Electromagnetic Radiation
Crosscutting Concepts - Structure and Function
