Great organizer for First Grade Light Sources in Spanish
Log in to see state-specific standards (only available in the US).
Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light. Examples of materials could include those that are transparent (such as clear plastic), translucent (such as wax paper), opaque (such as cardboard), and reflective (such as a mirror). Assessment does not include the speed of light.
Make observations to construct an evidence-based account that objects can be seen only when illuminated. 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.
