Listen up! We are constantly exposed to sounds from televisions, radios, traffic, and even each other. When present at safe volumes, these sounds don’t affect our hearing, but, if the sounds are too loud or last too long, hearing may be compromised. Students perform tests with a vibrating tuning fork to observe how sound waves travel through air and how they affect liquids and solids. Students even perform the Weber and Rinne tests to analyze their own hearing followed by thought-provoking questions that force them to think about their own auditory health.
Kit includes enough materials for five student groups— sodium chloride, plastic wrap, five tuning forks, and five plastic cups.
