Ballou 2016 Mr. Meyers Unit III (Waves) WAVE Interactions Ballou 2016 Mr. Meyers Unit III (Waves)

Kick-Off Complete sentences ~ 5-7 min Mr. Meyers A1, A4, A5 3.3 2/6/2017 1. What do you see when you look at your self in a mirror? Why does this happen? 2. Why does your cellphone lose its signal when on the metrotrain? TIER 2: Provide an example of one of the three Laws of Motion. Be sure to state which law is being highlighted.

Turn, Talk, Share, & Write ~ 3 min When I say START, pass your lifeline to your nearest neighbor For 45 seconds each student will edit their partner’s responses to the lifeline. Write 1 glow and 1 grow from their responses + = At least three complete sentences, few to no grammar errors = A minimum of two complete sentences some grammar errors - = Does not complete lifeline on time, sentences incomplete The person that WOKE UP the EARLIEST will SHARE the SUGGESTIONS and EDITS on their partner’s LIFELINE, FIRST. Students will be RANDOMLY called to SHARE OUT what THEIR PARTNER discussed. BE PREPARED TO SHARE!!

Agenda ~ 1 min In Class: Homework: Lifeline Objective Turn, Talk, & Write Objective Organized Binder Check Cornell Notes Types of wave interactions? Independent Reading Chapter 20 section 3 Scholar Groups (TEST YOUR KNOWLEDGE) Learning Log Homework: Complete “Properties of Waves” Chp 20:3 (G3.4)

Announcements STAY FOCUSED so we can meet our OBJECTIVE. PHONES ARE AWAY!!! Due TODAY Binder Check – Everyone should have a binder Quiz 3.1 CLOSED Grades are OUT!! Missing Assignments can ONLY be made up if excused absence. NEWSELA STAY FOCUSED so we can meet our OBJECTIVE.

WRITE OBJECTIVE IN YOUR LEARNING LOG (OWN WORDS) ~ 2 min By the end of class students will compare and contrast reflection, refraction, and diffraction by deconstructing informational text and performing mini-investigations in small groups. Standard: HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media. WRITE OBJECTIVE IN YOUR LEARNING LOG (OWN WORDS)

Wave Interactions EXPLORATION ~ 2 min Instructions: When I say START, you and members of your assigned group will INVESTIGATE several wave interactions and identify each phenomenon based on your notes. Draw a diagram and describe your investigation in the summary portion of your notes. Rules: Every group member must contribute No cellphones 2 minute timer Responses must be written down before the timer runs out Be prepared to share

Why do waves reflect? ~ 2 min A reflection occurs when a wave bounces back after hitting a barrier. All waves can be reflected Sound waves reflecting off a barrier are called an echo.

Why do waves diffract? ~ 2 min Diffraction is the bending of waves around a barrier or through an opening. The amount of diffraction of a wave depends on its wavelength and the size of the barrier opening.

Why do waves refract? ~ 2 min Refraction is the bending of a wave as the wave passes from one medium to another. The wave changes speed as it passes from one material to the next. The resulting wave bends and travels in a new direction. When light waves pass through a prism the different colors travel at different speeds through the droplet

Draw a diagram and describe your investigation in the summary portion of your notes. Rules: Every group member must contribute No cellphones 2 minute timer Responses must be written down before the timer runs out Be prepared to share

Critical Thinking Questions ~ 8 min Critical Thinking Questions How does refraction relate to wave speed from our lessons, last week? Construct a Venn Diagram to compare reflection, diffraction, and refraction Why is it important to understand how waves interact with other objects? Use specific examples

Independent Practice (15-20 min) Scholarly Studies Option 1: Read Chapter 20:3 “Wave Interactions”. Complete Cornell Notes SILENTLY for Chp 20:3 Students that attempt AND are successful with BLANK Cornell Notes will receive 5 extra credit points. At the end of 15 minutes you will be graded on your overall performance. + = All important topics are completed, written neatly. = Missing a couple topics and remained on task for the majority of the time - = Unable to complete 1 pg of Cornell Notes, remained distracted

SCHOLAR GROUPS (TEST YOUR KNOWLEDGE) ~ 1 min Rules: Every group member must contribute No cellphones 1 minute timer All answers must be written down before the timer goes off WITH page numbers When I say START, you and members of your assigned group will DEMONSTRATE your COMPREHENSION from the text by answering questions. Each group will have 1 minute to answer the question and support their answers using a text. Reward: 1st place 100 hero points, 5pts extra credit on quiz

Question 1: Draw an example of refraction? TEST YOUR KNOWLEDGE ~ 1 min Question 1: Draw an example of refraction?

Question 2: Compare and Contrast refraction and diffraction? TEST YOUR KNOWLEDGE ~ 1 min Question 2: Compare and Contrast refraction and diffraction?

TEST YOUR KNOWLEDGE ~ 1 min Question 3: Is this statement true, “The amount of diffraction of a wave depends on its wavelength and the size of the barrier opening”? Why or why not?

Question 4: What does light do when it disperses? TEST YOUR KNOWLEDGE ~ 1 min Question 4: What does light do when it disperses?
