Boo--Powell has the flu

Today you will be

I.  taking a test
II. working on a phet lab using this document

DO NOT print the document.  Simply #1 to 15 in your notebooks and answer.

Ok, finish the work from Friday to start.

Then we need to think about two pictures:

and this document, which Christine will go over with you on the overhead screen.

http://phet.colorado.edu/files/activities/3551/prelab%20for%20mechanical%20motion%20KE%20PE.doc 


Then complete this and hand it in. (there should be printed copies of this to be handed in.)

Machine Exploration

Go to Edheads and pick at least 2 rooms room in the house.  In each room, search for 10 machines.  Make a list of the machine (for example, maybe it's a pencil sharpener) and the simple machine type for your journal today.

Good luck.

Mousetrap car body ideas

Tuesday-Thursday

What machines will a mouse trap car have?  Well, you need a body, wheels, and a mousetrap.

The mousetrap is a lever.  What type?  Does this make things faster or easier?







Here, we have two machines (3rd class lever and a wheel and axle) with an AMA less than 1.  What does this do for the racer?   How can we maximize this factor for the wheels?
===============



BY 12:30, please tell me or Christine if you are going with Option A, Option B, or Option C.

If you choose to analyze a pre-made video, you'll need to do the following.

1.  Watch the video.  Note the times that you observe the terms above.  For example, you may see negative acceleration at :42-:54   You need to use all the terms above.
2.  Put the terms in order of time, not in the order above.  This will help you think about the way you are going to speak about things.
3.  Listen to some color commentators in a sports broadcast so you understand better what you are asked to do.
4.  Start writing your script.  I will ask to see what you have done tomorrow.

If you choose one of the other two options, please plan out what you are going to do on paper.  Again, I will ask for your documentation.

Final Project

All videos must show evidence of the following.  You must define the term individually and hand in, as well as including a stick figure example of each.

• Newton's First Law
• Momentum
• Pressure
• Inertia (non-moving)
• Inertia (moving)
• Impulse (F vs. t)
• Newton's second law comparison of two objects
• Balanced forces
• Unbalanced forces
• Pairs of forces
• Mass
• Constant speed
• Acceleration, +
• Acceleration, -

Option 1:  Choose a YouTube video of a motorized sport. Identify each of the above terms and and a time associated with it.  Define each term.  Make a video voice over like a weekend sports' announcer that is entertaining and shows your understanding of the terms using a podcast tool.

Option 2:  The year after a teen gets his/her license is the most dangerous year of his or her life.  Use your knowledge of the concepts above to help keep kids safe by making a video for http://www.toyotateendriver.com/teens/video-challenge

Option 3:  Make a stop-motion movie that is at least 10 seconds long that tells a story. Explain in a summary how it uses what you learned in this unit.

Sample Video

Crumple Zones Test

Find a car that has a five star driver rating.  _____________________________

Find a car that has a three star driver rating.  _____________________________

Watch the videos of both undergoing a front end collision.

What happens to the crash test dummy in each.  Be specific.

What safety features does it have?  Be specific

Add to your thoughts by going here:  http://www.pbs.org/wgbh/nova/escape/timecar.html

Which would make a better demolition derby car, in your opinion?

Blue Book Analysis vs. Safercar.gov

Kenz's and Devin's group:  http://t.co/2VQmy07tYk 

Marshall's group:  http://t.co/WLFpDksXi6

Chaunda's group:  http://t.co/hQdgVhMDT8

Zoe's group:  http://t.co/r2KULubSlU


Using these cars, (or send me a tweet with different ones), go to safercar.gov and look at three cars.  Rate the safety of three cars, making some type of chart to support your reasoning (hint--use a rating scale or look at p. 8)

CLAIM

EVIDENCE

REASONING

argument for each

Show Christine or Mrs. D your group's evidence.

Then, go to page 9 of your book and write in YOUR NOTEBOOK the answers to questions 1, 2, and 3.

================

Wednesday:  Write the answers to the journal questions in your notebook.

Read p.  11, Physics Talk.  (pair read, talk, and create pair examples)

Come up with four examples each of the two physics words on the right.

Read p. 12.

Class discussion questions:

How do the safety systems from yesterday impact the possibilities suggested on p. 12?

Answer the Journal Write and the What do you Think Now on p 13
