Experiment Title: Making a Bell Sound with Clothes Hanger and Spoon
What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: The purpose of the experiment was to determine if I could make a bell sound using a clothes hanger and a spoon (separately).
What was your hypothesis?: My hypothesis was that the hanger bell would work and it would make a bell sound. We didn’t make a hypothesis for the spoon because we did this with our Grandma and she forgot to ask us for a hypothesis on the spoon.
What materials did you use in your experiment? List them all.: The materials we used were:
1. a metal clothes hanger
2. 2 strings
3. spoon
4. wooden table or chair
What procedure was followed? Provide a brief description of the steps you followed during your experiment.: First we tied a string to the hook part of the metal clothes hanger, making it so there were 2 about equal length hanging from the knot. Then we put the two strings to our ears (one string to each ear). Then we stood by the wooden table or chair and, still holding the strings to our ears, gently hit the clothes hanger on the table. Repeat the same steps for the spoon.
What were the results of your experiment?: The experiment did work and the bell sound did happen very clearly for both spoon and hanger. The hanger sounded more like a bell and the spoon sounded more like a piano key being hit.
What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect? What did you learn?: My conclusion is that my hypothesis was correct. I never knew you could make a bell with such simple items. It was really cool to find out that you can. I really think my Grandma’s experiments are awesome. So are my mom’s.
