St Kevin's Primary and Nursery

Friday, 30th September 2016


This week our Primary Three scientists have been investigating how sound travels, and the effect that distance can have on sound.

We learned that sound travels through vibrations and waves which we were able to feel on our own throats. We then tested how distance can affect the way we hear sounds, first by shaking a maraca at various areas of the school and seeing if we can still hear it from the chalkboard, before doing the same with a person speaking at normal voice level.

We then looked at one of the most famous Scottish inventions – the telephone, before trying to make string telephones from plastic cups.

Our string telephones were a success! We learned that the sound could only travel through the string if we pulled it tight to allow the vibrations to move from cup to cup.
Well done P3 Scientists!!

  1. Nathan really enjoyed showing us and telling us all about what he’s been learning in science. It was lovely to see photos of what he’s being doing in class. I can’t believe how much you know about sound already Nathan, well done!

  2. Everyone loves what you guys are usually up too.
    This sort of clever work and exposure! Keep up the good works guys I’ve added you guys to
    my personal blogroll.
