How Loud Is Too Loud?
How loud was that? Individuals build wheels displaying different sounds. Then, learners use the wheels to find the number of decibels the sound creates and how long they could withstand the sound before potential hearing damage.

Sound Measures
How loud is the class's hearing threshold? Using a sound level meter, the class members observe how the loudness of sound is affected by distance. Learners continue to study decibels by seeing how different sounds compare to each other...

Sound Absorption Wall
What types of materials absorb sound? Learners explore sound waves, the decibel scale, and how different materials affect sound. Then, they use their knowledge of sound meters to complete a STEM engineering design task to build...
