Hello everybody,

Today we did a experiment for sound. We watched a video about the experiments.

I was in a group with two boy no girls but it was Okay. I worked on my collaboration skills with kids i wouldn’t work with normally. Here we are making the telephones:

 

Experiment:

Experiment 1 we made yogurt cup telephones it only sooooo weird! We had to attach different types of string to the cups to see if sounds travelled. It did a little bit but i think we need a better string and a quiet space to listen. Here are my friends trying the experiment.

We also made a model of the ear to see how sound travels to the brain.
