Science experiment 3

yesterday on the 23rd of June we did our third science experiment this one was based on sound so..... we did the cup and string thing here is a example of what it looks like

we got into partner's and one person would say something into one cup and then the other person would put their cup on to their ear and the two cups would be connected to a piece of string and the sound would travel down the piece of string and go to the person's ear and vibrate the eardrum and that would make them hear what the other person was saying through the cup we had to answer some questions about what it would be like if you are around a corner being around the corner didn't change how we heard the person speaking but when we tied a knot and the string it didn't do anything also then we were challenged to undo one knot of through the cup and cut the string in half and see if the shorter length of string Made difference. It did! it made the noise  louder...... or maybe that was just because we were closer together . But it was a very fun experiment to do here are some more photos 

BYE!
