Your instruments

Go to Flutomat to calculate the length of your pipes in centimeters

I need a post that details...

What your instrument will be
The materials you are using
Your song
Your partners
Your notes (e.g., C4, D3, etc.)
Your frequencies (261.31 Hz, etc)
Your wavelengths (.8 m, etc.)
The lengths of your note pipes or strings


Now, go to Flutomat to calculate the length of your pipes in centimeters

The role of the mouthpiece...

A mouthpiece is designed in such a way that it concentrates, or forces sound across a column of air.  How did you do this with the straw instruments you designed last week?

How do you make a kaleidoscope?

Yesterday, we worked with lasers and mirrors to reflect light. How do you think the pattern above was created?  How many mirrors would you use?

What is resonance??

Give examples of resonance using light and sound waves.

Videos on Electromagnetic Radiation Applications

Electromagnetic Radiation

Today we will be taking notes on the electromagnetic spectrum. You will need to take a link at the links here, here and here.

MAKE a drawing of the spectrum in your white notebook. Label 7 types of waves, where the longest frequency is, where the shortest frequency is, where the longest wave is, and the speed of light in a vacuum.

Draw a transverse wave and label parts.... crest, trough, amplitude, node, wavelength

List 5 ways we use electromagnetic waves each day!

Today I am sick, so please follow these directions and COMPLETE THE BLOG POST BELOW.

TEST is postponed to Friday.

===
Use the computer or Google text to define the four following terms
frequency
period
amplitude
wavelength

(To use Google Text, text define _____(put the word in) and send to 466453)



You will be going a wave simulation. Work in groups of 3. The worksheet for today can be found here (print off an activity sheet for your group) and the actual activity can be found here I am looking for word observations, not a formula.

Looking at Data

Today, I want you to look at the data found at the link at the bottom of this post. Clicking on a county or state will give you more data. What trends do you see in the counties of Iowa (remember, Red is Republican, Blue is Democrat)? What trends do you see in national map? Take a look at Delaware, Clayton, and Buchanan counties, which make up the West Delaware school district. What does this tell you about how people in our school feel about the election last night?
