Discover the speed of light and what it means to measure objects in “light years”
MODEL CURRICULUM (GRADE 5) Physical Science
TOPIC- Light, Sound, and Motion
CONTENT STATEMENT- Light and sound are forms of energy that behave in predictable ways. Light travels and maintains direction until it interacts with an object or moves from one medium to another and then it can be reflected, refracted or absorbed.
GRADE 5 CONCEPTS- Light can travel through some materials, such as glass or water. Light can also travel through empty space, like from the sun to Earth.
