``` Name: ______________________________
Date: _______________ Activity Sheet 1: Waves Activity 1: ___ 1) Set up and turn on your wave generator. ___ 2) Adjust the knob until the wave is steady and creates a wave pattern. ___ 3) Sketch what the wave looks like. below: Activity 2: ___ 1) Find the white spot on the string and note where it is. ___ 2) Turn the wave machine back on, adjusting the knob until the wave is steady, and observe the string. ___ 3) Which direction does the red string appear to be moving? _______________________________________________________________________ ___ 4) Which d irection is the white part of the string moving? _______________________________________________________________________ ___ 5) What is giving the wave its energy? _______________________________________________________________________ ___ 6) What is the m
aterial the energy is moving through? _______________________________________________________________________ Information taken from: "Ducksters: Education Site for Kids and Teachers." 2006. 22 Apr. 2014 < h ttp://www.ducksters.com/ > Name: ______________________________
Date: _______________ Activity 3: Diagram: ___ 1) Turn on the wave machine and adjust the knob until the wave is steady. ___ 2) Find the l ine of equilibrium on the diagram. Use a ruler and measure the height of the string from the table. Record this in the box on the diagram. ___ 3) Find the c rest on the diagram. Use a ruler and measure the height of the string’s crest from the table. Record this in the box. ___ 4) Find the t rough on the diagram. Use a ruler and measure the height of the string’s trough from the table. Record this in the box. ___ 5) Find the difference between the c rest and the l ine of equilibrium . This is called the a mplitude of the wave. Record this in the table on the next page.

Date: _______________ ___ 6) Find the difference between the t rough and the l ine of equilibrium . This is also called the a mplitude of the wave. Record this in the table below.
Results: Height (cm) Difference (cm) Crest Trough Question: What do you notice about the differences for the c rest and t rough ? _______________________________________________________________________ _______________________________________________________________________ Information taken from: "Ducksters: Education Site for Kids and Teachers." 2006. 22 Apr. 2014 < h ttp://www.ducksters.com/ > Name: ______________________________
Date: _______________ Activity 4: ___ 1) Turn on the wave machine and set it so that you get two or more crests. ___ 2) Use your ruler to measure the distance between two of the high parts of the wave (crests) in centimeters (cm). This is called the w
avelength . Wavelength = ___________________ ___ 3) Predict (hypothesis) what you could you do with your wave machine to make the wavelength either shorter or longer. Hypothesis: _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ ___ 4) Test out your prediction and see if it is correct. Write your answer (conclusion). Conclusion: _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ Information taken from: "Ducksters: Education Site for Kids and Teachers." 2006. 22 Apr. 2014 < h ttp://www.ducksters.com/ > ```
