Physical Science A

Bellwork:
    1.  What is an electromagnetic wave?

    2.  What are some of the forms of energy found on the electromagnetic spectrum?

Objectives:
    1.Identify the different regions on the electromagnetic spectrum and compare them in terms of     wavelength, frequency, and energy.

    2.  Explain why radio waves can travel through space, but sound waves cannot.

    3.  Explain why there is a time delay between the time we send a radio message to astronauts     on the moon and when they receive it.

    4.  Explain why we see a distant event before we hear it (e.g., lightning before thunder,     exploding fireworks before the boom).
   
Collect Test Remediations.  Check Binders

Discuss the electromagnetic spectrum and the forms of energy found on it.

HW: Write one page on which form of the electromagnetic spectrum play the biggest part in your life.  Explain why it has such a big impact.  Give examples of how you use it daily.

Physics A

Bellwork:
    1.  If I apply a 100 N force to an object and cause it to move 2 meters, how much work is being done?

    2.  What happens to the amount work done if the angle that I apply the force is increased to 40 degrees?      Do I still do the same amount of work?  If not by how much does the value change?
