Making a Phone Using Two Cups and a String

First Name: Anna
Age: 7
Experiment Title: Making a Phone Using Two Cups and a String
What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: The purpose of this experiment was to see if I could make a phone using two cups and a string.
What was your hypothesis?: My hypothesis was yes – the cup would work. But I already knew it would work from a book I read.
What materials did you use in your experiment? List them all.: I used:1. a cup
2. string
3. 2 paper clips
4. scissors
5. brother
What procedure was followed? Provide a brief description of the steps you followed during your experiment.: First, we cut the string and made it very long so we could talk to each other from far away. Then we punctured a hole at the bottom of each cup and put the string through each hole, making a line. After that, we tied a paper clip to each end of the string so that it was secured to the cups. Then we walked far apart so that the string was taut and then started talking into them.
What were the results of your experiment?: The cup phone did work well. Sometimes it was a little fuzzy and you couldn’t hear what somebody was saying. For example, I thought my brother said “hakuna-matata-ta-ta-ta” but really he said “Hi, Anna. I’m Aaron.”
What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect? What did you learn?: My hypothesis was correct. It is very cool how you can make a phone using only two cups, a string, paper clips, and scissors. And of course a friend! I learned that the cup phone sometimes isn’t clear, but that it still works good.
