I will know the behaviors of light. I will be able to incorporate text features that enhance nonfiction text material.

1. What produces electromagnetic waves? Electromagnetic waves are produced when an electric charge vibrates or accelerates. 2. How fast does light travel in a vacuum? 3.0×10 8 m/s 3. What makes electromagnetic waves different from one another? Different wavelengths and frequencies

A1: W HAT DOES INSULATION PREVENT ? A. the collapse of ceilings in homes Insulation does not help with structural support in homes. B. the unwanted transfer of thermal energy in or out of a building Thermal energy always moves form warm to cold areas. In summer insulation prevents thermal energy from moving into a building and in winter insulation prevents thermal energy from moving out of a building. C. the loss of thermal energy inside a building when it is hot outside In summer thermal energy moves from outside a building to inside because thermal energy always moves from warm to cold areas. D. the gain of thermal energy inside a building when it is cold outside In winter thermal energy moves from inside a building to outside because thermal energy always moves from warm to cold areas.

A student earns quarter grades of 2.1, 2.9, and 3.1. What does the student’s 4 th quarter grade need to be to raise the overall average to 3.0? Average grade = ( th quarter grade) ÷ 4 = 3.0 ( th quarter grade) ÷ 4 = 3.0 Next multiply by 4 on both the sides th quarter grade= 12 4 th quarter grade= 12 – 8.1 = 3.9 So, Melissa has to score 3.9 in her 4 th quarter in order to get an overall average of 3.0

Reflection Refraction Diffraction Interference

Reflectionoccurs when a wave bounces off a surface that it cannot pass through. Reflection does not change the speed or frequency of a wave, but the wave can be flipped upside down.

Refractionis the bending of a wave as it enters a new medium at an angle.

As an ocean wave approaches the shore at an angle, the wave bends, or refracts, because one side of each wave front slows down before the other side does. FUN FACT Refraction

Diffractionis the bending of a wave as it moves around an obstacle or passes through a narrow opening.

T URN TO A PARTNER – DISCUSS HOW A WAVE WOULD DIFFRACT IF ITS WAVELENGTH IS LARGE COMPARED TO THE SIZE OF AN OPENING OR OBSTACLE.

T URN TO A PARTNER – DISCUSS HOW A WAVE WOULD DIFFRACT IF ITS WAVELENGTH IS LARGE COMPARED TO THE SIZE OF AN OPENING OR OBSTACLE. -- ANSWER A wave diffracts more if its wavelength is large compared to the size of an opening or obstacle.

This wave diffracts, or spreads out, after it passes through a narrow opening. Picture of Diffraction

Interferenceoccurs when two or more waves overlap and combine together.

Constructive interference occurs when two or more waves combine to produce a wave with a larger displacement. Types of Interference

Destructive interference occurs when two or more waves combine to produce a wave with a smaller displacement. Types of Interference

A standing wave is a wave that appears to stay in one place—it does not seem to move through the medium.

S MALL GROUP : Complete a graphic organizer on the four behaviors of light. Draw a picture in each box and write a sentence to define each behavior.

E LECTROMAGNETIC W AVE R EVIEW A CTIVITY The teacher asks a question and gives think time. (60 seconds BEFORE you can begin writing) Students think and then respond independently in writing. (No talking) Finally, students share their thoughts one at a time around the table (or circle) Continue around the table until the teacher says stop.

T HINK -W RITE -R OUND R OBIN : What are the five categories of nonfiction text features?

F IVE C ATEGORIES OF T EXT F EATURES 1. Text Divisions 2. Organizational Tools 3. Graphics 4. Font Size or Formatting 5. Layout

G ETTING THE MOST FROM YOUR TEXTBOOK : H OW TO USE TEXT FEATURES Text features include the physical features of the text that highlight the important content. – Table of contents – Glossary – Index – Charts and graphs – Headings – Insets and sidebars – Maps – Diagrams and cutaways – Bullets, asterisks, and stars – Captions and labels – Timelines – Types of print – Photos and pictures

CategoryDescriptionExample 1. Text Divisions Identify how the text is organized and presented Chapters, sections, introductions, summaries, and author information 2. Organizational Tools Help readers understand key topics or information Titles, table of contents, index, headings and subheadings, glossary, pronunciation guide, and references 3. Graphics Visual representations that help the reader understand the main text better Diagrams, charts and tables, graphs, maps, labels, photographs, illustrations, paintings, cutaways, timelines captions 4. Font Size or Formatting Any change in font that signals the reader that this is important Boldface, italic 5. Layout Include aids that point readers to important information Insets, sidebar, bullets, and numbers
