How Does Light Travel?
Science Background: Light travels in straight lines, and this activity allows students to observe light and think critically about how they experience light in their lives. A common misconception for students is that the light comes from their eyes to light up the object, so drawing rays as arrowheads that show the direction of the light is a key concept.
Materials: index cards, ruler, coloured markers or pencils, hole punch, sticky tack, drinking straw, flashlight or ray box, beaker or glass, water
