Mr. Arce-Larreta from Salt Lake City UT is requesting supplies through DonorsChoose, the most trusted classroom funding site for teachers.

Physics Of Sound

My students need a tuning fork set, 15 slinkys, and a logitech speaker system for a labs on: finding the speed of sound, wave characteristics and interference.

Celebrating Hispanic & Latinx Heritage Month

Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Students

Science and engineering will provide most of the future jobs and industry in our country.

Our students are 9-12th graders in an urban city high school.

About 60 percent are on fee waivers due to low income. My classrooms include a diverse mixture of low-income students as well as high income high achieving students. I teach AP and IB Physics and general physics.

My Project

The students ability to apply concepts from the book to real world applications will help them understand and learn the material. Engaging students with hands-on learning will also help many students who do not learn from a lecture or from reading textbooks. The tuning forks will be used to estimate the speed of sound in a resonance lab. The tuning forks when held over an closed pipes will resonate at harmonics which can then be used to calculate the speed of sound. The slinkies will be used for a hands on lab to generate longitudinal and transverse mechanical waves. Many wave characteristics can be generated by these objects to introduce students to wave mechanics. The dual computer speakers will emit sound waves with matching frequencies from two sources. They will naturally interfere constructively and destructively with each other. The students walk around the room and hear differences firsthand. These tools will be used in engaging activities in the science laboratory.

Helping us with this project will help future inspire future scientists and engineers.

Sound engineering is vital to the the current music industry. Students love learning this topic as music often connects them to physics and science.
