1. Write your problem from the first page, then answer your problem(question). How will changing the surface of the penny (by adding soap) affected the number of water drops the penny can hold? The answer is that by changing the surface of the penny, the penny holds less drops of water because the soap is filling up the cracks, and the surface. 2. Write your hypothesis from part B.
If we change the surface of the penny by putting soap on the penny then, the penny will hold less drops of water, and we will get different results then the original.
3. List at least 3 pieces of data from your experiment(and your textbook/notes) that shows support for or refutes your hypothesis.
My hypothesis was supported by my data, I know this because I predicted that the soapy penny would hold less number of drops compared to the clean penny or the penny with no soap.
The data from my lab is as shown: our groups clean dry penny held 31.8 drops but …show more content…
Describe how your group’s results compared to the other groups in your class.
For part A, my groups data was similar to the class data because of our group average was 31.8 which the other groups were also around the same average as we had gotten at 20-30 drops of water.
For part B, my groups data was similar to the class data because our group average was 15 drops which the other groups were also around the same average as we had gotten at 10-15 drops of water.
6. Provide at least 2 possible reasons for any differences you identified in #5. Explain why these reasons would cause the differences you observed. One reason for this could be variation this would cause a difference because it makes it to where we are going to get different results than one another by say different soap type is one of them. A second reason for the differences could be the dropper this would cause a difference because we can get many size drops on the penny compared to one same size
