Reflection
Readiness
TEKS Objective
Demonstrate that light travels in a straight line until it strikes an object or travels from one medium to another and demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces, and refracted such as the appearance of an object when observed through water.
Essential Understanding
The student knows that energy occurs in many forms and can be observed in cycles, patterns, and systems.
