Today is presentation and project day.   Each group will present their project to the class.  Remember that everybody in class has to present.  Everyone is nervous.  Just relax and have fun with it. 

When all the groups have finished, we will continue out discussion of renewable vs. nonrenewable resources.

Physics B

Bellwork:
    1.  Explain the difference between a virtual image and a real image.

    2.  How do the formation of the images formed in a concave mirror change as the object changes postition     relative to the focal point?

    3.  Make generalizations about the image position and orientation for a concave and convex mirror.

Go over the ray diagrams and the color lab.

*******Keep up on you WORK!!!!!!***********
Discuss practical application and uses of light and mirrors.

Group Explanation Challenge:
You will work in groups of three to explain all the items bellow.  Place the explanations on the information sheet.
1.  How do headlights work?
2.  Why is the sky blue?
