1-PS4-2: Illumination and Darkness

Make observations to construct an evidence-based account that objects in darkness can be seen only when illuminated. (Cause and Effect)

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. Illumination could be from an external light source or by an object giving off its own light.

Assessment Boundary: none


The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour.  These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection. Learn more about assessment design here.




Appearance (e.g. visible, not visible, somewhat visible)
