Those students who attended class worked on their optics presentations.
Homework:  for Thursday, Refraction lab report; for Friday, Optical Device Presentation

The index of refraction is a ratio of the speed of light in a vacuum to the speed of light in some other medium.  It is an optical property of that medium.  If you need help with the concept and calculations, read p.524-525 in the text.
Homework:  p.525 #2, 3, 5-7, 9; refraction lab report
Presentation is due Friday.

We completed this experiment today.  Consult your handout for proper lab report format and hand in the report for this experiment by Wednesday.

We used the period to work on your assignment that is due next Friday.  Continue this work on the weekend.

We had a quiz on light and reflection today.  We completed an activity to see how the refracted rays of light were related to incident rays of light shone through a semicircular prism.
Homework:  complete the calculations in your observation table and answer discussion questions b, c, e, f, g, i on p.521; continue work on your presentation

We learned what causes refraction today, and the rules to predict how a ray of light will refract.  See the text, p.515-519.  We will have a quiz on light and reflection in mirrors tomorrow. 
Homework:  continue research for optical device; answer p.519 #2, 3, 5; review mirror concepts by reading p.504 and answering p.506 #1-3, 7, 9-13

We spent time researching chosen optical devices to develop a presentation about them.  The presentations themselves are due on Friday, March 2.  You must hand in your visual, rough notes, and list of references in APA format right after your presentation.
Homework:  continue research on your optical device

Convex mirrors are also called diverging mirrors.  We completed diagrams to show how rays of light can be used to predict the location of the image and its characteristics for both concave and convex mirrors.  Look at p.497-500 in the text.
Homework:  p.501 #3, 5-8, 10

We completed an activity to investigate how light rays reflect from a concave mirror.  Read p.497-499 in the text.  The handout, "concave ray diagrams", can be printed from the SNC 2D Physics unit page of this site.
Homework:  complete the ray diagrams on the handout, front only

No class for per.4 due to assembly.
Per. 5 class watched video about mirror use by Archimedes.
