This Properties of Light poster is designed to aide students in understanding that light travels in a straight path until it strikes an object. From there, light is either reflected (bounced) off the object or refracted (bent) as it passes through the object. Convex and Concave lenses bend light. Light is refracted because it changes speed as it enters a new medium; Light travels through air (gas) and enters a glass of water (solid and liquid) which causes light to slow down as it passes through the glass of water.
The Texas TEK (5.6C) is listed within the poster inlcuding if the TEK is a Readiness or Supporting Standard. The verb and nouns are highlighted in a color other than black.
Students should be read the TEK before the lesson begins. The teacher and the students should discuss the TEK; the students need to understand that the verb is what they have to do once the teacher is finished with the lesson. The nouns include, but are not limited to, the vocabulary contained within the lesson.
Once I created the poster, I used a poster maker to blow-up the original size (8.5 x 11) to a true poster size document. I hung the Properties of Light poster at the front of my class and used this method as the ENGAGE part of my lesson. I allowed students to use the poster as a "cheat" throughout the lesson. Once I was finished with the unit, I took the Properties of Light poster down to begin a new unit.
