Light Show Details for Tuesday and Wednesday

You have Tuesday and Wednesday to do this.  It's due BEFORE Break.

====================
GRADING RUBRIC

Note that this a 50 point project, and is your assessment for light and sound. It is a benchmark.

Make a video using the web cam or a flip camera or cell phone that tells a story.   It must use a series of shadow puppets.  Audio will be added to this eventually.  Be thinking of the following as you do this:


Personal Writeup


  1. What colors can you see on the completed video?   
  2. What color of shadows can you see?  Is this the same or different?
  3. What does the color tell you about the story?   The mood?
  4. Can you explain a plot with a beginning, a middle, and an end? (Answer in one or two sentences)
  5. List a specific example in your video where there is a fuzzy-edged shadow( ____seconds)  How was it formed?
  6. List a specific example in your video where there is a sharp-edged shadow( ____seconds)  How was it formed?
  7. List a specific example in your video where there is a larger shadow( ____seconds) than the puppet.  How was it formed? 
  8. List a specific example in your video where there is a smaller shadow( ____seconds) than the puppet. How was it formed?
  9. A List a specific example in your video where there is a penumbra, or lighter shadow( ____seconds)  How was it formed? 
  10. List a specific example in your video where there is an umbra, or darker shadow( ____seconds)  How was it formed?
  11. Were there any wavelengths of light you could not see in your video?   How could you tell?
  12. Make a table and compare the qualities of light and sound.
  13. Explain how you could improve your video to make the mood better through lighting or to make the quality of the shadows better.
  14. Explain what each of the people in your group did on Tuesday and Wednesday.  Be very specific.

QR Codes: Applications of Light

Today, you will be making a scavenger hunt using QR codes


STEP 1:  Watch the video



STEP 2:  Find out about qr codes https://sites.google.com/a/lshigh.org/gotbooks/qr-codes
and be able to compare them to bar codes.

STEP 3:  Decide what your qr codes will link to:

  • a website
  • a location on google maps
  • a clue (perhaps on twitter or weebly) that will require you to solve a riddle
  • other ideas
Here's how one person figured it out:   http://ilearntechnology.com/?p=4211
Here is another:   http://storify.com/720mi/qr-code-scavenger-hunt  (this includes the video above, as well as other ideas)

STEP 4:  Plan your hunt and make the qrcodes:   http://www.qrstuff.com/ is one maker that is kind of cool, but there are dozens of them out there.

Your QR scavenger hunt must have at least seven clues, which should be saved as .png or .jpg and pasted onto a word document.  Send this to me at the end of the class..   The groups are as follows:

Christina A
Kristin S.
Michael C

Aaron D
Clayton L
Cassidy O

Jake P

Sarah M.
Jordan W.

Blake S.

Electromagnetic Spectrum Notes

Teachers' Domain: Tour the Electromagnetic Spectrum
Teachers' Domain: The Electromagnetic Spectrum: FRONTLINE
Teachers' Domain: Tour of the Electromagnetic Spectrum: Radio Waves





  • What are electromagnetic waves?





  • What is a photon?





  • Name one manufactured device or natural phenomenon that emits electromagnetic radiation in each of the following wavelengths: radio, microwave, infrared, visible light, ultraviolet, X-ray, and gamma ray.





  • Which type(s) of electromagnetic radiation do human bodies emit? Which type(s) can our senses detect?





  • List three ways that electromagnetic radiation is used to improve our everyday lives. 


  • ============

    Everybody has at some time thrown a pebble into a puddle and observed the ripples spreading across the surface.  Some of us don’t stop until the puddle has been completely filled with every loose piece of debris in the vicinity.  Now let’s dive in a bit deeper into the physics.

    1)      Before you change any settings
    a.       What is the shape of the pulse?
    b.      How can you explain this?  Talk about crests or frequency.
    Reflection:
    2)      Increase the amplitude to maximum.
    3)      Turn off the water and add a vertical wall (bottom right button) across the entire width of the tank.
    4)      Turn on the water for just a couple of drips.
    5)      Observe the wave reflection from the barrier
    a.       What is the shape of the reflection?
    b.      In what ways does it differ from the incident (incoming) wave?
    c.       Compare this result to what you learned about reflected pulses from the wave on a spring demo?
    Interference:
    6)      Allow the faucet to run.  Feel free to adjust the frequency.
    a.      What do you think the particularly bright and dark spots represent?
    7)      Show the graph and observe the last couple of waves in front of the wall.
    a.       Once again, considering the wave on a spring demo, what do these last waves on the graph remind you of?
    8)      A second example of wave interference can be seen by removing the barrier and turning on a second drip
    a.       Draw or describe the resulting pattern.
    b.      How are the dark & light stripes similar to and different from standing waves?  (Hint:  Look at the graph again)
    c.       What do you think may be happening along the gray rays?
    d.      How can you test your ideas?  Hint:  Consider the purpose of the horizontal dashed line.
    e.       Perform the experiment.  Was your hypothesis supported or rejected?
    9)      Adjust the drip frequency, pausing a few seconds for the image to stabilize after each change.
    a.       How does drip frequency relate to the number of rays?
    b.      What is the range for the number of rays you can generate?
    c.       Is there a pattern?
    10)  Return the frequency to full and double the drip spacing.
    a.       Now how many rays can you count?
