Rainbows and Human Eye (in library on 5/2/11)

Today I would like you to investigate how a rainbow is formed and how the human eye sees things, including how nearsightedness and farsightedness are corrected.  These concepts correspond to questions 12 and 14 on your 14+15 Review Sheet.  Both of these concepts will be short answer questions on your test on Thursday.

Instructions for Rainbows:
1.  Go to The Physics Classroom Link (bottom one)
2.  Go to Physics Tutorial
3.  Go to Refraction and Ray Model of Light (last one I think)
4.  Go to Lesson 4 and pick Rainbow Formation

Focus on the diagrams for how a rainbow is formed.  What 2 things happen to the light waves?  (think about the wave properties we have discussed).  Draw a picture of what happens in the water droplet.  If blue comes out on top of the droplet, why is it that red is on top of the rainbow that we see?  What 3 requirements are needed to see a rainbow?  (this is in the very last sentence of the rainbow section)

Instructions for The Eye:
5.  Follow previous instructions in Physics Classroom, but go to Lesson 6 (The Eye)
6.  Read about Anatomy (a), and Image formation (b)
7.  Read about farsightedness and correction (d)
8.  And nearsightedness (e)

Check out the eye diagram and how the human eye works.  How does the lens help focus to near and far?  What is wrong with a person's eye if they are farsighted and how is it corrected?  What is wrong with a person's eye if they are nearsighted and how is it corrected?

The Week of 5/2-5/6

• Monday 5/2:  Go to library.  Check off Lens HW and go over.  Look up rainbows and nearsightedness and farsightedness (instructions/questions will be on this blog).  Then do project research and/or LoggerPro graph for Snell's Law Lab.

The Write-up:

1)            Labeled diagram including metric measurements

2)            Mechanical advantages (probably ideal) for 3 simple machines

3)            Discussion of 3 other Physics principles that are involved in your machine.  Explain them

4)            Write a paragraph describing the challenges and successes you experienced in doing this project.  What would you change?

The Week of 2/1-2/4

Welcome to the 2nd Semester!

Tuesday 2/1:  Return Final Exams and recollect.  2nd Semester Survey.  Notes on Simple Machines.   Video:  "The Way Things Go."
Thursday 2/3:  Notes on Mechanical Advantage and Efficiency.  "How to make the perfect lever lab."  Another machine video.  Introduce machine project.  Brainstorm with group.
Friday 2/4:  Problems with mechanical advantage and efficiency.  Work on machine project.

Final Preparation

By this time I think I have graded everything that I have from you and the grades have been entered into Edbox.  If you see an inaccuracy or if you have a question, please e-mail me.  The Physics in Motion Projects were truly a delight to read.  I learned a lot about the different sports and activities and it was fun to see how you all applied the physics.  There were a few projects that had missing parts that can be made up. 

Answers to the Semester Review Packet are posted in the documents section.  I highly recommend that you work through the problems to prepare yourself for the final.

Remember the notecard guidelines:
1)  No bigger than 4 x 6 (in inches)
2)  Can write on both sides
3)  Must be hand-written by you, no photocopying
4)  The card will be collected after the test (if you really want it back, you can get it back later)

What you need for the final:
1)  1-2 decent pencils with erasers
2)  A scientific calculator that you know how to use
3)  Paper for the problems and short answers
4)  Something to do if you get done early

I will provide you with the equation sheet that is in the documents section.  The test has about 30 multiple choice, 9-10 problems, and 3 short answers.  I expect it to take most people at least 1.5 hours.  Unless you have an IEP or 504 that gives you more time, you need to complete the test in the 2 hours allotted. 

Your best preparation is going over the review sheet and/or notes and making a good notecard of the things that you find hard to remember.  Other than that, remember to breathe and take the questions one at a time.  If one is frustrating you, move on and come back to it later.  Try not to spend too much time on the multiple choice.  Frequently your first impression is correct, and second-guessing yourself can be counterproductive.

We will be going over the Review Packet on Monday and Tuesday, in addition to clearing up any questions about grades.  If you have any questions about the material or your grade, don't hesitate to ask.  I will be available for Test Corrections and help on Tuesday at lunch.

Your Late Work and Extra Credit Deadline Has Been Changed Until Tuesday By the End of Lunch!!

You do not have to do the last 3 because we didn't cover angular momentum mathematically.  However, there will be a conservation of angular momentum problem for extra credit, so if you have time, it may be worthwhile to go over that.

The Week of 1/17-1/21

I hope you had a nice 3-day week-end!  We have 1.5 more weeks in the semester, so make sure that you know what you need to get done.  The Semester Review Packet is now on-line, so you can get started on the review if you would like.  How is your project?  Make sure that you follow the guidelines so that you don't lose points for forgetting something.  There will be a short 7+8 test on Friday, followed by review for the Final Exam.  The late work and extra credit deadline is Monday 1/24!    Late work deadline has been changed until Tuesday at lunch!!

Monday 1/17:  Martin Luther King Day.  No School.
Tuesday 1/18:  Turn in Torque Lab if not already.  Introduce Conservation of Angular Momentum and demonstrate.  You will only be responsible for understanding this conceptually.  Problems 1-5 on page 294 will be extra credit if you want to do them.  Work on 7+8 Review (See documents if you don't have this.  You can skip the last 3 problems).
Wednesday 1/19:  Mid-day FLEX.  Come in for help on either of the review or to work on your project.
Thursday 1/20:  Motion Projects are due.  We will do a walk-around evaluation in the back of the room.  Go over the 7+8 Review Sheet and start going over the Final Review Packet.
Friday 1/21:  Turn in 7+8 Review.  Take short 7+8 Test.  More going over the semester review packet.
