Physics+20

__**December 22**__ Physics students missing today. You need to complete this exam and hand it in to me 9:00 Jan. 6th. I won't accept any exams after this time. __**December 14th**__ - Finish Solar Cookers and design plan. - Type up plan and hand it in - When finished, go through the following optical illusion lesson 1) Research what optical illusions are, types of optical illusions, and how the physics of light is related to these. Record this information in your notes. 2) Listen to the following podcast: [] 3) Look through various optical illusions. Share interesting ones you find with your classmates. Here are a couple good websites [] [] Science of Optical Illusions []

Make sure you also include your design plan and justification for it. Why did you pick that design? What principles of physics do you think are at work? What considerations did you make when designing it. i.e. why did you choose tin foil and black paper/paint.

__**December 10th**__ - Started Solar Cooker background research __**December 9th**__ - Finished definitions from yesterday - Read Plane Mirror Notes - Complete Light Reflection Assignment (#1 to 6) - Activity: Using 2 plane mirrors, determine the angle that produces the most images of an object. In your notes, make a table showing the angle and the number of images produced. You must have at least 10 angles recorded. __**1950's Light Video**__ media type="youtube" key="BWp47NVnBig?fs=1" height="385" width="480" __**December 8th**__ - Law of Reflection Lab - Define the following terms and create a diagram showing how they are all related: interface, normal, point of incidence, angle of incidence, angle of reflection, law of reflection, incidence ray, reflected ray, boundary. __**December 7th**__ - Finished Video: The Mechanical Universe and Beyond: Optics - Finished Light Handout Questions 1 to 5 on the problem set - Activity: How many times can you make a laser bounce? media type="youtube" key="XRLRSdgvLg0?fs=1" height="385" width="640"

__**December 6th**__ - Worked on Light Handout Question. 1 to 13 are Due for Tomorrow - Started Video: The Mechanical Universe and Beyond: Optics __**December 4th**__ - Create an experiment that demonstrates the rectilinear propagation of light - Activity: Show how light behaves when it passes through a transparent, translucent, and opaque object __**December 3rd**__ - Start Light Unit 1) Define the following: luminous, nonluminous, rectilinear propagation, beam, incandescence, ray, transparent, translucent, opaque, penumbra, umbra, eclipse 2) Give examples of common luminous and non-luminous objects 3) Identify objects that are transparent, translucent, and opaque __**December 2nd**__ - Physics Exam __**December 1st**__ - Missed Class - Course Selection __**November 29th**__ - Exam Review - [] __**November 25**__ - Doppler Effect

__**November 24**__ - Mechanical Resonance and the Tacoma's Bridge - Discussed vibrating air columns/made straw flutes Notes: media type="youtube" key="ASd0t3n8Bnc?fs=1" height="385" width="480" __**November 23**__ - Worked on Sound Module #2 __**November 22nd**__ - Finished stringed instrument lab and recorded observations. To be handed in at end of class. - Started working on Sound Module #2 - Discussed resonance: the frequency objects tend to vibrate at

__**November 19th**__ - Worked on stringed instruments lab __**November 18th**__ - Noise Pollution Articles. Find article, summarize for class, and record in notes what noise pollution in and examples of noise pollution - Constructive vs. Destructive Interference

[] []

__**November 17th**__

- noise pollution articles --> need to know what noise pollution is and examples of noise pollution

__**November 16th**__ - Wire Telephone Experiments __**November 15th**__ - Finished Speed of Sound Assignment __**November 10th**__ - Speed of Sound Assignment --> Questions 1 to 5 Due

__**November 9th**__ - Musical Instrument Lab __**November 8th**__ - From your balloon observations, you should know that sound travels slower in carbon dioxide then it does in air. This could be why we heard "muffled" noises. If anyone wants bonus marks, figure out why carbon dioxide seemed to be heavier (perhaps more dense) yet the speed of sound was slower. Bring your answer to me. __**November 5th**__ - Magazine article summary


 * Magic of Physics Assignment:** Many magic tricks are based upon an understanding of the science of physics. Tricks such as lying on a bed of nails or walking over hot coals can be analyzed through an understanding of surface area and heat. For this project, you need to search the internet or other print resources to find a magic trick. Once you have selected a trick, you will gather the necessary materials and practice your experiment. You will then present the magic trick in front of the class with an accompying summary of how physics plays a role in your selected experiment.

 * __September 8th__**
 * Welcome to Physics 20! Physics involves the study of matter and energy and how they interact in nature. Many students fear physics even though it deals everyday things such as light, heat, sound, etc. Our goal for this class will be to understand these concepts and apply them back to our everyday experiences.**

- Attached is the course outline. It will be provided in class, but will also be posted here in case you ever need to refer back to it.

- We also read the article: "What is Physics?", and created a mindmap connecting physics to different disciplines.
