Hello there today I am going to tell you about how does sound travels !
today in science class we did science experiments.
The first experiment I did was called the coat hanger experiment.
Hypothesis : I don’t think the light will travel through the coat hanger.
conclusion: The sound traveled to my ear when the scissors hit the coat hanger!!
The second experiment was called the yogurt cup telephones .
Hypothesis: I think the sound would travel through the string to the other cup.
conclusion: In the end it did not work the sound did not go through the string.
The third experiment is called the sound salt.
Hypothesis: I think the sound will stop in the salt
Conclusion: The sound stops vibrating in the salt it also stops on your hand!
The fourth and final experiment is called the sound water.
Hypothesis : It will vibrate the water when you put the metal things in the water.
