Hello? Grade 4 Blue Builds String Telephones

Ms. Kornobis’ class recently worked in Science the lesson on sound and waves and had a fun activity to understand what they learned. They built tiny telephones made of plastic cups and wool threads. Then they tested if sound went through and the partner on the other side was able to receive the message. Some groups tried to put together three and even four cups! Alo, can you hear me?
