Tuning fork lab
Guiding Question: How does density of various solids affect the way the sound waves travel from the tuning fork?
Sophia hypothesis:i believe that if the surface is stronger the sound will be lower and if it is thin it will be louder.
Philipp’s hypothesis: Probably if the material is thicker it won’t vibrate that much. I think that solid will make a lower sound. Glass can vibrate better, because it is way thinner. That is why some people can break a glass by singing.
Exploration/plan&to do a test:
Materials:
Procedure:
1) First we need to gather the materials we will need.
2) Second of all test and write down observations.
3) Thirdly we need record and analyze.
4) and then we will do the further inquiry.
Material Density Loudness
Analyses&data:
Philipp’s analyses: I figured out that it not always depends how thick or how thin an object is. For example the white board does not vibrate that much and the table makes a higher sound. I thought that the table will make a lower sound than the board but it was the opposite. Also the small tuning fork makes on the different objects sometimes higher and sometimes the lower sound.
Sophia's analysis:what i discovered is that there is a difference on the sound and the materials of the object made of,makes a different sound in some thing it did not vibrate as much other materials.
Conclusion:
Philipp’s conclusion:I think that I learned a lot about sound and that I tested it good. It is interesting what the difference between to different objects is. Also the differences between the two tuning forks are interesting. Sometimes the smaller one is higher and sometimes the bigger one. This was funny and interesting. I liked to explore the density and loudness between objects.
Sophia's conclusion:i conclude that if the object density changes the loudness of when it hits it. it depends of the object and what it is made out of.
Further inquiry:
Philipp’s inquiry: I think that I learned a lot. I learned everything about sound and also explored it. I think a made a great job. In the class I worked a lot. This lab is maybe the best I have ever made. In this lab i tested a lot of different materials and used the best ones.
further inquiry: i believe that doing this lab i learned more abut more sound waves and how they travel i tested a lot of different things and different materials (locker table).

Good layout of the lab report. Just the variables were missing so we could see what you were testing for. The data analysis was very general and needs to be more specific examples from the data table. You had a good conclusion, but how could you improve the lab? What would you do differently? Was your hypothesis different in the beginning?
