In the Quiet the Skies activity learners design and build a Thunder Drum to simulate jet engine noise. Then learners design and build chevrons to reduce the simulated jet engine noise.
Quiet the Skies: How do you reduce jet engine noise?
Objective: Understand how sound is created and how to reduce noise.
Scenario and Task: You are an acoustics engineer. You will design, test and improve a sound-damping system that uses chevrons to quiet jet engine noise. Decreasing the sound level by increments of at least 3 dB can significantly reduce human risk.
AeroEducate 6-8 Activities are developed for learners to investigate topics such as lift, stability, friction, the Magnus effect, and sound. Designed in a 5-E lesson format, each activity begins with an essential question, incorporates a career component through a real-world scenario, and introduces age-appropriate vocabulary. Background information for the facilitator is included. Posters that illustrate key concepts associated with the lesson can be printed or viewed electronically. Separate student directions and templates are included as needed.
Full access to the activity and supporting resources is provided once free registration to the AeroEducate website is completed.
AeroEducate is a series of STEM activities developed by the Experimental Aircraft Association (EAA) in cooperation with North Carolina State University and the National Institute of Aerospace. EAA is a passionate community of aviation enthusiasts from diverse backgrounds.
