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.](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/light) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/light) [![](https://www.knowatom.com/hubfs/Light1.jpg) ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/materials-and-light) ## [Materials and Light In this unit, students explore the science phenomena of light and the relationship between sight and light.
