Puppet Show reflection

• Tell me WHY the shadows are the shape they are in your video clip. 

• Explain how you got colored shadows, where there is an umbra, and where there is a penumbra.

• Why did you choose to have the shadows be the size they are, and how could you have made them bigger? 

• How did the colors you used set the mood for the music you will use?

• How could the shadow show be modified to make the shadows as small as possible?

Straw Flutes

Today, you will explore the possibilities of instruments with straws. First, try to make a reed instrument with a straw. To do that, use a straw and cut it like this.

Or check out this link


Next, try to make a musical flute using straws of different lengths using the sample picture






















A slide flute can be made using straws, also.






You can also make flutes with test tubes by adjusting the amount of water in each tube. Use the test tubes in the sink to the left of the microwave, and wash them (with soap!) when you are done.

The goal, of course, is to make a flute that can play a beautiful tune. When you get a flute that does this, make a 10-20 second video of your piece using the camera on my desk (batteries are on the microwave)

Here are two examples:





WHEN YOU ARE DONE, DO 6 of the Physics to Go questions at the end of Lesson 4.
