Sound Experiment 2014

Sound Through Different Medium

1. QUESTION/OBSERVATIONS

How does different medium affect sound?

2. HYPOTHESIS

I predict that the different materials we use will affect the quality of the sound though the cup telephone.

3. EXPERIMENT

Equipment/Materials: At least have 2 cups. Strings. Nylon. Thick wool. Ribbon. Toothpick. Ruler (to measure the length.)

Process/Method: 1. Get 2 cups and put a hole through the bottom in the middle. 2. Measure your medium (string,nylon etc) so they are exactly the same length. Attach the medium to the cup with a toothpick. 3. Test - Make sure each test the string/medium is taut. 4. Rape the sound and record.(Quality/How loud)

4. RESULTS

What are the results that you came up with? Well the result that I came up with is really good. Their was 3 different kinds of strings that we had to use and they all sounded different as well. The most scariest one of them all was the wire one. It sounded like you were talking to someone on the other side of a dark and creepy cave.

5. CONCLUSION:

This experiment that we got to do was so cool and exciting the entire class enjoyed and so did I. I really hope we get to do this again because it is cool to make cup phones for your self. Wouldn’t you want to make something that cool with your classmates?
