This week we have been focusing on images formed by curved mirrors. Tonight's homework is to analyze the data that you have gathered on so (object distance) and si (image distance).  As you look at the graph of so and si, please follow the analysis directions (attached below).  Your answers to the analysis questions on this sheet must be included in the analysis and conclusion sections of your formal lab.

Also, be prepared to share the equation and results of your analysis in class tomorrow.

This week, we learned how light forms images.

We are ending this week in waves working on two activities.

Thursday: Review Waves Investigation, introduce wave superposition. Homework: Waves Worksheet 4 (the odd problems)
Friday: Answer questions on odd problems.  Homework: finish even problems on Waves Worksheet 4.
Start EM Waves group research project.  This project is a group presentation of research about a particular electromagnetic wave.  You will do most of your research and presentation preparation at home.  This will require you to collaborate with your partners at home online (email, facebook, twitter, google+, GoogleDocs, SMS, etc.).  Due date - next Friday.

You can find the most up-to-date instructions on our class website: class.dannug.com. Look for section 13: Light, Optics & EM spectrum.

Here are the following groups and research topics:
1st Hour -
Alex M, Michael D, Anthony S - Gamma Rays
Alex F, Julie W, Calvin S - X-Rays
Zac D, Jimmy M - Microwaves
Belicia T, Eunice K - Visible Light
Khalid I - Infrared
Geoffrey P, Trevor M, Jason C - Radio Waves
Anitta V, Saadia S - Ultraviolet

3rd Hour -
Wayne S, Omkar S, Edmund Q - Visible Light
Austin W, Mike C, Justin F - Infrared
James H, Becca C, Lauren A - X-Ray
Ah Young K, Jeff H, Carlie Z - Microwaves
Kevin H, Evan W - Radio Waves
Surab S, Joel B, Saad M, Syed A - Gamma Rays
Mandi R, Amanda V, Zerilda X - Ultraviolet

Monday: Waves investigation Day 1
Tuesday: Waves investigation Day 2
Wednesday: Finish Waves Investigation Day 3.

Go out and experience some physics!

Monday: Begin Pendulum Lab
Tuesday: Finish Pendulum Lab and complete the springs lab extension. 
If you did not finish the labs in class, make sure to finish them for homework.  The pendulum lab requires you to graph your results and determine if there is a mathematical relationship in each of the three data sets.  If there is a pattern, determine the equation for the pattern.

The Spring Lab Extension activity should be done in your journal after the pendulum lab.  The directions for the lab is on our class website class.dannug.com.

Both labs are to be done by tomorrow (Tuesday).

Have fun and experience some physics!

Monday, we reviewed the concepts of momentum, impulse and collisions through the use of clickers and through questions and answers.

Tuesday, we completed the test on momentum.

Wednesday, we will begin discussing motion of objects in a circle.

On Friday, we used iPads to analyze the motion of carts colliding with
each other. Through this, we calculated the momenta before and after
the collision.
On Monday, we wrapped up the lab with a discussion of the results.
On Tuesday, we discussed the law of momentum conservation and
practiced applying this law to collisions. The homework given was
momentum worksheet 2.
On Wednesday, we will answer questions on the homework and discuss
inelastic collisions.

In case you were wondering, there is a scanned answer sheet for the unit 8 review on our class resource site, class.dannug.com. Look for it in the Energy section, linked at "view the answers for the UNIT 8 REVIEW".

So, go experience some physics!
