Objective: Students will be able to review relationships between the parts of waves, in order to explain properties of waves and wave behavior. Homework: --Benchmark Review Packet (Due Friday) -- GET A NEW NOTEBOOK FOR MONDAY!!!

2. Review Amplitude and Frequency– NO relationship Amplitude and Magnitude(Energy)- Direct Wavelength and Frequency- Indirect Pitch and Frequency- Direct Loudness and Amplitude- Direct

3. Agenda Assignments Homework 2 (Sound) Homework 3 (Sound review) Exit Ticket (The Colors We See) Tomorrow: Review Game Thursday: Day 1 of Test – 20 multiple choice Friday: Day 2 of Test- 2 BCRs

4. Review: What’s Wrong With This? The Grass is green because it absorbs the other colors of light.

5. Review: What’s Wrong With This? The grass is green because the grass is reflecting green and absorbing all other colors. White light is all colors combined to form white.

6. Review: What’s Wrong With This? Refraction is different from reflection because the angle of incidence is greater measure for reflection than refraction.

7. Review: What’s Wrong With This? Refraction is light going inside something and reflection is light bouncing off of something.

8. Review: What’s Wrong With This? Refraction is different from reflection because refraction means the bending of light and reflection means light bouncing off of an object. In the investigation on Thursday, we try to see if the laser would go through the jello or reflect off the jello. The laser went through the jello and bent. This is refraction. The laser bouncing off the mirror was reflection.

9. Benchmark Review: BCR Challenge! Today, we will work together in pairs to complete the BCRs for a BCR review. You will submit your group’s answer on loose leaf. The remainder of the packet is for homework and will be reviewed tomorrow during the review game. The winning group will receive extra credit on the exam!
