Kyle's Own Lab: Testing the different substances

The Own Wave Lab:

Testing the reaction of the Waves when different Substances are added.

How does the unlike substances react to the wave’s movement?


Kyle C.

Due Friday, January 28


TITLE: Shows all the necessary information (Title of the lab, your name, grade, date)

I. GUIDING QUESTION/S (State the guiding question/s):

How does the unlike substances react to the wave’s movement?
How do waves move in different substances?

II.HYPOTHESIS:

I believe that, depending on which substance, the wave’s movement (Frequency) will alter.

Independent Variable (Manipulated): The pen or the Stick (I guess or not [Wait, does manipulated variable have to be always solid?])
Responding Variable: Wave
III. Exploration (PLAN & DO A TEST):
Materials
  • Water (Normal and Bit Hot)- (Principal of Substances)
  • Orange Juice (Substance)
  • Honey (Substance)
  • Soap Water (Substance)
  • Salt Water(Substance)
  • Ruler
  • Notebook
  • Writing Pencils
  • A Plastic Bowl (for testing)
  • Pen
  • Rubber Duck or A round floating object (Test as a boat)
  • Timer





Procedure:
1. Gather a Plastic bowl size of approximately 40 width by 20 length cm.
2. Fill the Plastic Bowl with water depth of 5 cm (this is what I did).
3. Then add any substances (besides water) of approximately 3 cm (think about if ducky can flow)
4. Stir the water with the substance for a minute, place the plastic bowl at the center and probe/move around with the stick or your hand.
5. As probing the water, estimate and observe the speed and the behavior of frequency.
6. Then, Place the circular object (the boat) above the water and move it around the water. (Depending on the consistency/fluency, the object will react unlike)
7. Record the time of the frequency; Record the frequency of the Wave when the object is traveling.

IV. RECORD & ANALYZE (Calculated by Finding the average of 3 Trials) [1Wave is produced every sec]

Observation
(Kyle’s observation)
As I found the frequency of Orange juice, I discovered that there is not much a difference between the frequency of water and orange juice.Due to the consistency and the fluency of the liquid, it was formidable to watch the wave’s movement. But I assume that, the data has been organized well.After the 3 trials, I found that the liquid NOT ADDING foam/ producing foam wasn’t that fluent as the water due to the consistency.After observing the behavior of the salt water which traveled an average of 1.208 w/sec, I examined the interval of first try & second try. I wrote that 3 trials were needed in-order to find the correct frequency.
Short Analysis
(Kyle’s opinion)
Low fluency gives clear wave (think that made sense...)Compared to the taste, I believe the honey maintains high fluency.

Taste: Good
Fluency : High (Would not able to swim due to liquid)
With or Without no foam, I think that the frequency of both aren't that different.The Data suggests that my first try was bit off of the actual w/sec (waves per second.




Analysis of the Data:
Least to Greatest Frequency: Orange Juice - Salt Water - Soap Water - Honey

I had found that the consistency and the fluency were the matter and the solution to the substances. The liquids had maintained consistencies; besides the estimation, I discovered today that while the object was floating/traveling, it bounced or jumped once. I wondered if it was the reaction to the wave or the force. Therefore, I observed that lower the frequency: clear and easier to examine.



IV. Concept Acquisition (CONCLUSION):

(My guiding question “How does the unlike substances react to the wave’s movement?” and “How do waves move in different substances?” my hypothesis “I believe that, depending on which substance, the wave’s movement (Frequency) will alter.”)
My guiding question and the hypothesis proves/tells that I tested the lab efficiently and correctly however my hypothesis was not precise or in other words “didn’t explain my knowledge.” By comparing the results in the data, I found out that lower the frequency- more visible the substance appears. I also comprehended/determined the ways of wave’s interaction when using oil, as a fact when oil was above the water and I forced the oil-water wave to collapse, the oil wasn’t mixed with water since those 2 are never posed to go together.
In conclusion, I can assert that the liquid will be more visible and clear to identify depending on the disturbance causing to react. (Guess that made sense too)

I will try to be positive and confident above my topic; I’m not sure if my data was correct however I assure myself that this was a just a test for myself to learn step by step (so practices make perfect).

V. Concept Application (FURTHER INQUIRY):

For the last “Concept Application,” (Further Inquiry) I would like to draught some major improvements and successes down if I have a chance to re-dew. As this lab of “doing alone” was fun and interesting when no one was bothering, I kind of felt that there had to be partners or groups to work with since, the works can be divided and worked equally rather than alone. Nevertheless, I found this alone lab, tranquil and relaxed since I was the one who was in charge. On the other hand, I assume that this lab made my bathroom a mess due to the honey.
Although I was confident about my guiding question & concept of my lab, there were tremendous mistakes I got confused with. It just occurred to me that I had to be tidy/organized when writing up the lab (since I anticipate for a higher grade). The result was not precise when I recorded the results of the frequency, but I believe that I could have checked if my results were applicable. (Some went off the average score) I was bit unsure that testing on a circular shape tub or plastic bowl might have affected the results. Last but not least (Love the phrase), I regret that during class periods I should have concentrated and finished as some of my classmates did. Otherwise, I believe that not a single disruptions or errors happened during the lab (isn’t it amazing?).

The pink symbolizes the tub, as the manipulated variable hit at the center, the wave will move sideways and hit against the wall; then reflect or bounce back.

  1. Good job on collection of data and organizing it as well. Please be sure to think through your report and revise your work before you publish it in order to communicate everything well.
