From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . Intro to Refraction. Take 3 cups from the front, labeled 1,2,3. . Observe each straw through the side of the cup as you slowly turn the cup. . DO NOT STIR THE CONTENTS!. Write down your observations. . What has happened in each example and why?. I think this is called.... It happens when.... It happens because.... The air is.... The water is.... The light usually. travels...but when it hits water.... Presented by: Vandana Bathla & Eric Williams. Light Refraction. Have you ever wondered why it appears we see puddles of water on a highway on a hot summer day?. What you are seeing is not really water, but a mirage.. Define refractive index.. Demonstrate refraction.. State the Laws of Refraction.. Solve problems about refraction.. HL: Solve problems about refractive index in terms of relative speeds.. Give examples of refraction in nature.. How to Play . 1. Divide the class into 5 teams and assign one of the following 5 colors to each team: red, yellow, green, blue and orange.. 2. Using your list of questions, ask each team a question. If they answer correctly, click their team gingerbread man and a decoration will appear on the cookie.. light bends or refracts when it moves from one medium to another. the light bends because it changes speed. if light slows down it bends toward the normal. if light speeds up it bends away from the normal. 2. Take the time “make friends” with Slide Master functionality. . (warning: at first it can be frustrating!). Create Master Slide layouts before adding any content . if at all possible. . It will make your life easier.. No feature should be used to the point that it is annoying, but you should know how to use many features so you can use them judiciously.. Here is a boring slide. The background is boring.. Choose a more interesting background, particularly if this is to be read/run without your commentary.. Stephen Kyle. University College London. s.kyle@ucl.ac.uk.

If you find yourself feeling out-of-sorts, pick up a book.According to a recent study, reading can significantly reduce stress levels. In as little as six minutes, you can reduce your stress levels by 68%.
