Question: What material best muffles the sound of a timer?
In order to solve this problem, the Magical Minds scientifically investigate how well a variety of materials worked at muffling the sound of this little chicken timer. We took turns, placing the timer in different materials (cardboard box, metal can, fabric…). We measured how well it worked by measuring how far away from the timer we had to be before we could not longer hear it.
What is your hypothesis? Which material do you think worked best?
