Physical Science A

Bellwork:
    1.  Draw a graph that shows objects:
                    -moving towards at a constant speed
                    -moving towards at an increasing speed
                    -Moving towards at a decreasing speed
                    -Moving away at a constant speed
                    -moving away at an increasing speed
                    -moving away at a decreasing speed

    2.  Explain the difference between:
                    -scalar vs vector
                    -distance vs. displacement
                   
    3.  What is the average velocity of an object that travels 480 km in a time of 10 hours.

    4.  What is the velocity of a plane traveling at 350 km/hr, heading into the wind with blowing at 20    
    km/hr?

    5.  What changes will cause an object to accelerate?

-Practice Test

-Check over the objectives today.

-Organize the binder

-Study for test!

Physical Science B

Bellwork:
    1.  How is the electricity that we use daily different from the electrostatic discharge we get when touching a     charged object?
   
    2.  Explain the concepts of voltage, current, and resistance.  When you have finished answering the     bellwork, take a moment and explain this answer to the person next to you.

    3.  What factors affect the resistance of a wire?

Check and go over the Ohm's Law homework and vocabulary.  Use the whiteboards to check.

Discuss series and parallel circuits.

HW:  Schematic diagrams.  Finish the schematic diagram packet.  We will check and go over these tomorrow.
