Sound waves
We were trying to solve the problem of there is
too much noise so we made earmuffs. First we learnt that some objects make
echos like bars and poles. Then we learnt that rubber blocks sounds waves the
best.I used cardboard, foam, fluffy wool, glue gun, pva glue and rubber to block the sound the best. I made mine in two days. I can only hear with them off. Mine are comfy too. I do writing with them. I do reading too. I have a straps made of loom bands. I love my earmuffs.
Miss Langdon took a photo of everyone’s earmuffs. All of them block sound by 50%. I would call them the blockers. They were for blocking sound waves. People that used rubber in their ear muffs hardly heard anything.
