Grade 4: Do You See What I See? (4-PS4-2)


In this unit students learn about how light enters the eye and they are able to see objects. There are multiple opportunities for students to discover what is happening with light bouncing off of objects and entering our eye. Students understand that you can change the direction of light by placing mirrors in the light’s path. They understand that if you put multiple mirrors at different angles, you are able to see something that is out of the eye’s point of view.
