Quarter Credit: For this quarter, course work will consist of:  2 projects 10 pts each  2 test 10 pts each  Daily 3 questions 40 pts total (1 pt per day)  Participation 20 pts total · In class (approximately on time, still in room when bell rings, only reasonable amounts of time out of the room) · On task (head up, working / participating, not distracting or disrupting others) Other than tests and possibly projects, students //must be present// to earn credit. (Make-up work for //excused// absences will be available on the class website and are to be handed in within a week of returning to class.)

<span style="font-family: Arial,sans-serif; font-size: 14pt;">Perfect Attendance Bonus: <span style="font-family: 'Times New Roman',serif;">Any 13 consecutive school days of attendance is eligible for a 5 point extra credit bonus, up to 3 bonuses per quarter. For multiple bonuses, the 13-day periods cannot overlap.

<span style="font-family: Arial,sans-serif; font-size: 14pt;">Expectations: <span style="font-family: 'Times New Roman',serif;">It is expected that anyone choosing to be in class is working toward our goal of learning enough physics to get credits. Respect is fundamental to helping everyone achieve that goal.

Thur 5/24 - Main Sequence

- MAP testing, "Through the Wormhole" videos in room when done.
 * Monday - Wednesday 5/21-23**

Make-up: Complete project using guide below - Research and make a slide on 1 topic from at least 3 different categories
 * Wednesday - Friday 5/16-18**

Make-up: Watch the video at the link below. Answer the questions in the attached viewing guide. http://video.pbs.org/video/1456686369/ - Video Nova: Hunting the Edge of Space about the development of telescopes
 * Tuesday 5/15**
 * == Advisory 2nd hour**

- Tests back - Re-do flashlight and screen experiment using a magnifying glass - Compare converging mirrors to converging lenses
 * Monday 5/14**

- Use glass blocks to measure how they bend light - Learn angle of incidence and angle of refraction, which are measured to the perpendicular - Use Snell's Law to calculate the speed of light in the block
 * Friday 5/11**

- Run a toy car from the table onto a towel and it changes direction! - When the car (or light) changes from a faster medium to a slower medium, when edge is slowed down first and the ray bends. - This bending at a surface is called reFRACtion - It's why a pencil or straw looks bent sticking out of a glass of water
 * Thursday 5/10**

Test!
 * Wednesday 5/9**

Make-up: N/A - Jeopardy! review day
 * Tuesday 5/8**

Make-up: Watch the video at the link below. Answer the questions in the attached viewing guide. http://topdocumentaryfilms.com/through-the-wormhole-does-time-exist/ - Video on experiments about time and different theories about how it works
 * Monday 5/7**

- Field trip to Pluto! - On 1:10,000,000,000 scale first 4 rocky planets are within sight of the school. - After Jupiter we walk 100s of yards to get from planet to planet (the gas giants, only marble sized) - Pluto and Neptune are almost to the YMCA
 * Friday 5/4**

Make-up: Watch the video at the link below. Answer the questions in the attached viewing guide. http://topdocumentaryfilms.com/the-fabric-of-the-cosmos/ - Video The Fabric of the Cosmos: What is Space??? - Space really is something and isn't just an empty framework!
 * Thursday 5/3**

- Ray diagrams for mirrors - By keeping track of a couple of rays of light from the top of the object, we can figure out where the image will form - Two rules: 1) In parallel - out through focus & 2) In through focus - out parallel
 * Wednesday 5/2**

- Experiment to find images formed by a concave mirror - Used a flashlight with a picture drawn on the end pointed at a mirror - Measured how far the object was from mirror and how far away a clear image formed on a screen - Found the focal length of the mirror - Looked what happened when the object was inside the focal length
