360Science™: Interference of Sound Waves

By: The Flinn Staff

360Science™ blends the best of student-engaging digital content with easily adaptable hands-on labs to offer your students a uniquely comprehensive learning experience.

In this lab experience, students will be able to demonstrate destructive interference of sound waves. By directing the sound wave from a tuning fork down two paths of differing length, the waves will be out of phase. When one of the path’s length differs by one-half of the wavelength, the waves will cancel each other out due to destructive interference. Editable, differentiated instructions range from a time-sensitive prescriptive lab to full open inquiry, and robust online videos and content help students prepare for and better understand the labs they’re conducting.

Product Details

360Science™: Interference of Sound Waves
Concepts:
Frequency, Wavelength, Speed, Interference, Longitudinal waves, Sound waves
Outcomes: Students will explore the destructive interference of sound waves produced by tuning forks. The destructive interference takes place by sending a sound wave down two paths of different length, provided one of the paths is longer than the other by half-a-wavelength.
Associated Phenomena: How can you tell that a guitar string is out of tune?

Our 1-year option provides access to all digital content for one year plus lab supplies for a single class of 30 students. Our 3-year option extends access to digital content to three years at a discount.

What is Flinn 360Science™?
We’re introducing a whole new way to teach experiential science! We’ve taken a hard look at science study from all perspectives and, thanks to the feedback of thousands of teachers nationwide, we’ve created a way to make it easier to provide personalized instruction while delivering the kind of lab experiences your students truly need.

Our new and comprehensive learning solutions are designed to bring science to life by giving you all the tools you need to incorporate more (and effective) hands-on learning in your classroom or lab. 360Science allows you to provide your students with the support they need to make real-world connections to key scientific principles and help make those abstract concepts concrete.

Every 360Science lab solves the most common challenges educators face in bringing more hands-on science to their students—from not having enough time to matching the right level of challenge for students’ abilities to providing appropriate background content, safety techniques, assessments and more.

Enable student-driven, blended learning through a unique combination of leveled lab instructions supporting prescriptive, guided- and open-inquiry lab exercises (see PDF resource for specific details) with robust digital content, such as videos and carefully curated Open Educational Resources (OER). From editable, digital instructions to assessments and alignment with Next Generation Science Standards (NGSS), we have everything you need to improve mastery, remove the intimidation factor and foster your students’ natural curiosity.
