Parts of a Wave Record the titles in purple in your notebook.

Set up your notebook so that it looks like the picture below. 1.Fold your paper in half. 2.Draw a line across the bottom section of your paper as see in the picture to the right. 3. On the top of your paper, label the left side My Parts of a Wave Definitions. 4. Label the bottom section Diagram. 5. Label the right side Class Definitions.

Raise your hand so that I can check your paper before you begin.

Crest - 1.Write the title above on the LEFT side of your paper. Remember! You will only be writing on the left side of your paper for the next few steps. 2.On the next three slides, you will see pictures that represent the word “crest.” While you are looking at the slides, think about what the pictures might have in common.

Crest

Create Your Own Definition 1.Use the pictures that you just saw to come up with your own definition of the word crest. Think about the similarities in the pictures, and decide what part of a wave the crest might represent. Do not look up the definition for crest. This definition should be in your own words. 2.Underneath your definition, draw and label the crest of a wave. 3.Your paper should look like this: Crest - (your definition) Crest

Trough - 1.Write the the word “trough” (pronounced tr-off) on the LEFT side of your paper a few spaces below your last vocabulary word. Remember! You will only be writing on the left side of your paper for the next few steps. 2.On the next three slides, you will see pictures that represent the word “trough.” While you are looking at the slides, think about what the pictures might have in common.

This definition should be in your own words. 2.Underneath your definition, draw and label the trough of a wave. 3.Your paper should look like this: Trough - (your definition) (with label of trough)

Make a Prediction! ●We have heard the word frequency before. ●We also know words that have a similar root: frequent, frequently. What does frequency mean in normal conversations? What might frequency describe if I am talking about a wave?

Frequency - 1.Write the the word “frequency” on the LEFT side of your paper a few spaces below your last vocabulary word. 2.On the next three slides, you will see pictures that represent the word “frequency.” While you are looking at the slides, think about what the pictures might have in common.

Frequency

OR

Frequency 1.Read all of the directions BEFORE you go to the website! 2.On the website, find the row labeled amplitude, and click the first dot. 3.Then, find the row labeled frequency. Click the first dot along the line that says amplitude. Then, click the first dot along the line that says frequency and press the button labeled “go.” Watch how the waves on the graph and under the boat change. STAY ONTHE FIRST AMPLITUDE button, but continue clicking the other frequency buttons. 4. Try to find similarities between the way that the waves change when you increase the frequency and the pictures that you saw on the slides before this. 5.

Create Your Own Definition 1.Use the pictures that you just saw and the simulation on the website to come up with your own definition of the word frequency. Think about the similarities in the pictures and the website to decide what frequency might mean for a wave. Do not look up the definition. This definition should be in your own words. 2.Underneath your definition, draw and label the frequency of a wave. 3.Your paper should look like this: Frequency - (your definition) (picture or pictures of frequency)

Make a Prediction! ●We have heard of words with the root amp: amplify, amp up, amplitude. ●We know that hooking an instrument up to an amplifier makes the sound louder by increasing the energy. ●We know that the drink, Amp, is an energy drink, like Red Bull. How might increasing or decreasing the amount of energy affect a wave? Would changing a wave’s amplitude, or changing its level of energy, change the way that a wave looks?

Amplitude - 1.Write the the word “amplitude” on the LEFT side of your paper a few spaces below your last vocabulary word. 2.On the next three slides, you will see pictures that represent the word “amplitude.” While you are looking at the slides, think about what the pictures might have in common.

Amplitude

1.Read all of the directions BEFORE you go to the website! 2.On the website, find the row labeled frequency, and click the farthest dot to the right. 3.Then, find the row labeled amplitude. Click the dots along the line that says amplitude. DO NOT click any more of the dots along the row labeled frequency. 4.After you click the dot, press the button labeled “go.” Watch how the waves on the graph and under the boat change. 5.Try to find similarities between the way that the waves change when you increase the amplitude and the pictures that you saw on the slides before this. 6.Click this link to get to the website: ph.html ph.html

Create Your Own Definition 1.Use the pictures that you just saw and the simulation on the website to come up with your own definition of the word amplitude. Do not look up the definition. This definition should be in your own words. 2.Underneath your definition, draw and label the amplitude of a wave. 3.Your paper should look like this: Amplitude - (your definition) (picture of amplitude)

Last Prediction! ●Our last word is wavelength. ●What two words can we make from the word wavelength? ●What does wave mean? ●What does length mean? Knowing what we know about the words wave and length, what do we think that the word wavelength might describe or measure?

Wavelength - 1.Write the the word “wavelength” on the LEFT side of your paper a few spaces below your last vocabulary word. 2.On the next three slides, you will see pictures that represent the word “wavelength.” While you are looking at the slides, think about what the pictures might have in common.

Wavelength

1.Read all of the directions BEFORE you go to the website! 2.On the website, find the measurement above the graph that says wavelength. 3.Notice how the wavelength changes as you change the amplitude and the frequency of the wave. 4.Look at both the graph and the measurement above the graph to see how changes in the wavelength affect the way that the wave looks. 5.Try to find out which has a greater effect on the wavelength - changing the amplitude or changing the frequency. 6.Click this link to get to the website: ph.html ph.html

Create Your Own Definition 1.Use the pictures that you just saw and the simulation on the website to come up with your own definition of the word wavelength. Do not look up the definition. This definition should be in your own words. 2.Underneath your definition, draw and label the wavelength of a wave. 3.Your paper should look like this: Wavelength - (your definition) (picture of wavelength)

When you finish your definitions... 1.Raise your hand so that I can check your work. 2.Then, go to the back counter, and take a sheet of class definitions. 3.Cut and paste these definitions on the RIGHT side of your notebook in the section that you labeled Class Definitions. 4.Cut out the diagram at the bottom of your class definitions sheet and glue it in the diagram section at the bottom of your page. 5.Compare your definitions to the definitions that you glued in your notebook. Are they similar? Is there anything missing from your definition? Did you notice anything that is not in the class definition? 6.Compare your diagrams with the diagram at the bottom of the page. 7.Raise your hand when you are completely finished so that I can check it and record your score.
