1 Exploring Energy Conclusions Answer the following questions based off the Exploring Energy Stations. Give as much detail as you can and avoid words like it and they. Please note: If the question asks why, do not worry about being accurate; simply explain what you think may have caused your observations. Part A: Defining Our Observations Refer to Stations 1, 2, and 3 when answering the questions below. 1. Describe what happened to the water when a vibrating tuning fork was placed into it. 2. Draw a model (i.e. picture, labeled diagram, or graph) that shows the impact a vibrating tuning fork has on the water. 3. Why does the Ping-Pong ball move? 4. Draw diagrams that compare and contrast what a single pulse sent down a slinky looks like before and after more force is added. Initial Force Increased Force 5. Imagine that you were able to view the depth of the pool when the waves were produced from the movement of metal arms. Draw a model that would show what you would have observed from the side. Labs and Projects 1

2 Part B: Using Sound to Enhance Our Observations Refer to Stations 4, 5, and 6 when answering the questions below. Name: Date: Hr. 6. What happens to your vocal cords when you change the loudness of your voice? Why does this happen? 7. Describe what happened to the sand when you changed your voice. Improve your description by providing an explanation of the changes you made. 8. Draw a diagram showing what happens to the paper clips when you increase the force on the drum. Light Tapping Increased Force Part C: Categorizing Our Observations Refer to Station 7 when answering the questions below. 9. Describe how sound and light are impacted when the vacuum was created. 10. What conclusion can be drawn from our observations? Part D: Modeling Our Observations Refer to Stations 3, 8, 9, and 10 when answering the questions below. 11. What happens to the white bobber when water waves were generated after metal arms began moving in the pool? How does this compare to the movement of the rubber ducky? Labs and Projects 2

3 12. Draw a model showing how a slinky moves compared to the motion of the energy when one person grabs a number of coils and pulls them close. 13. Draw a model that compares and contrasts the structure of the slinky when a faster motion is applied to a slinky moving side to side. Initial Motion Faster Motion Part E: Viewing the Properties Associated with Our Observations Refer to stations 10, 11, 12, and 13 when answering the following: 14. Draw a model that compares and contrasts the number of slinky waves produced when a faster motion is applied to a slinky moving side to side. Initial Motion Faster Motion 15. Describe how the sound produced by shorter keys (Let s Make Music) compares to the sound produced by longer keys. 16. How do the shorter tuning forks support your answer from above? Labs and Projects 3

4 17. Imagine that a slinky could show the differences in the sounds produced by the shorter keys and shorter tuning fork. What might a model of these sounds (represented with slinkys) look like? Longer Materials Shorter Materials 18. When you blew across the top of the bottle scales, you observed a low sound in the bottle with the least amount of water/most amount of air. When you tapped this same bottle, you observed a high sound. Why? 19. Imagine that a slinky could show the differences in the sounds produced by the bottle with the least amount of water/most amount of air. What might a model of these sounds (represented with slinkys) look like? Blowing Across the Top Tapping the Side Refer to stations 5 and 14 when answering the next two questions: 20. Imagine that a slinky could show the differences in the sand when you used the Cymatic demonstrator. What might a model of these sounds (represented with slinkys) look like? Quieter Sounds Louder Sounds Labs and Projects 4

5 21. Draw a model that compares and contrasts the height of the waves produced when a wider side-to-side motion is applied to a slinky moving at a constant speed. Initial Height Height after Wider Side-to-Side Motion Part F: Viewing the Behaviors Associated with Our Observations Refer to stations 15, 16, 17, and 18 when answering the questions below. 22. Why does the aluminum foil appear shinier after turning on the light? 23. Draw a model (i.e. picture, labeled diagram, or graph) that shows what might happen to sunlight when it strikes roads that are painted white. 24. Why does the pencil appear to be broken in once placed in the water? Support your explanation with a picture or labeled diagram. 25. Why did the water balloon affect your ability to hear during the funnel phone test? Labs and Projects 5
