Exploration of What Noises I Can Make Using a Cup, a Rope, and a Paper Clip
|Experiment Title:||Exploration of What Noises I Can Make Using a Cup, a Rope, and a Paper Clip|
|What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.:||The purpose of my experiment was to try to make sounds using a cup, a rope, and a paper clip.|
|What was your hypothesis?:||My hypothesis was that I could make a low-pitch squeaking sound but not a high-pitch squeaking sound.|
|What materials did you use in your experiment? List them all.:||one paper clip
|What procedure was followed? Provide a brief description of the steps you followed during your experiment.:||1. Use the blade of scissors to cut a small hole in the bottom of the cup – big enough for the rope to fit through but small enough so that the paper clip wouldn’t fall through.2. Tie the string onto the paper clip.
3. Put the string through the hole with the paper clip hitting the bottom of the solo cup.
4. Then try to make whatever sound that you want to try to make, by pinching the string and then rub your fingers down the string.
|What were the results of your experiment?:||The results of my experiment were that I could make a squeaking noise.|
|What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect? What did you learn?:||I thought that I could make the low-pitch squeaking sound, and I could make it. I learned that you can make squeaking sounds by rubbing a rope. Some of it was because the string vibrated and the cup made the sound because the sound waves bounced between the sides of the solo cup.|
