Join Talisa, Liseli, Arbnor, Mojtaba, and Afolabi as they conduct a fun and educational experiment to make earmuffs for Ms. Morrissey and prevent her from going deaf. Learn how they tested different materials like cotton wool, bubble wrap, and polystyrene to find the most effective option. Discover the importance of conducting a fair test and eliminating background noise for accurate results. This engaging activity teaches valuable lessons on sound insulation and experimental variables. See how the super scientists successfully create earmuffs and save the day!

Making Earmuffs For Ms Morrissey HELP I’M GOING DEAF AHHHHHH! HAVE NO FEAR TALISA,LISELI,ARBNOR,MOJTABA, AFOLABI IS HERE
The equipment for the super scientists Materials Data loggers!!! We’ve gotta make it a fair test!
What we used • Bubble wrap • Polystyrene • Cotton wool • Plan investigation sheet • Data logger • Sound source (shaker) • Ruler • scissors
What the super scientists did 1.We had to make the material the same size. 2.We had to be careful Of the back ground noise So we went to the waterloo room. 3.We then tested the materials and here are the results
What we learned • We learned that cotton wool is the best material for ear muffs because there is air in it. • The worst materiel was Polystyrene because it has holes in it so the vibration flow through. • The second best material is bubble rap because the vibrations get stuck in the holes.
What we would do different Never do an experiment with a background noise or else it will interrupt the sound experiment. Furthermore never swap the person who started the experiment because every body has different strengths.
