Physical Science B:(Monday)

Bellwork:
    1.  Explain the difference between a renewable resource and a nonrenewable resource.  Give examples     of each.

    2.  Why is the statement "Fossil fuels fuel our lives, without them life would become difficult to     nonexistent" such an ominous statement?


Everyone will need to have out their research sheets that were required for homework on friday. 


Groups: 
Each group will work together to discuss the forms of alternative fuels that you have researched.  You will use this as our note taking time.  The goal is to get a variety of ideas from each other.  The more information that is shared, the better you notes will be.  At the end, we will pull the class together, discuss all the information that you talked about in the smaller groups.

Begin the Sales Pitch Activity.

HW: Work on the Sales Pitch Activity

Physics B(Monday)

Bellwork:
1.  Which of the wave characteristic is related to the loudness of the sound.  What is the name given to the scale used to measure the loudness?  What are the units?

2.  What happens to the apparent frequency of a sound if the object making the sound is initially traveling toward you and then suddenly stops?

3.  What is the frequency range the typical human can hear?  What is it call above this range?  Below? 

Go over the doppler effect problems.

Go over the quiz.

Discuss Light and the electromagnetic spectrum.

Assignment:
    Research the various forms of the energy found on the electromagnetic spectrum.  Identify 3 uses for     each     form of energy.  Lastly, you need to pick the one form of energy on the spectrum that has made the greatest     positive contribution to the human civilization(visible light does not count!).  Back-up you pick with support.      The actual writing part of the assignment needs to be a minimum of one page.  

HW: Finish the 1 page assignment.
