1-ps4-2. Make observations to construct an evidence-based account that objects in darkness can be seen only when illuminated. [Clarification Statement: Examples of observations could include those made in a completely dark room, a pinhole box, and a video of a cave explorer with a flashlight.
In this unit, students continue to explore the phenomena of human senses, focusing on how objects can be seen when they are illuminated by a source of light, and how light passes through opaque, transparent, and translucent materials differently. Students then investigate how a beam of light changes when it hits a mirror.
This lesson helps students prepare for these Next Generation Science Standards Performance Expectations: 1-PS4-2 . Make observations to construct an evidence-based account that objects in darkness can be seen only when illuminated.
MS-PS4-2: Wave Reflection, Absorption, and Transmission Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials . ( Structure and Function )

(1-PS4-1), (1-PS4-3) Constructing Explanations and Designing Solutions. Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomenon and designing solutions.
