Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

The course treats the following topics: - Relevant physical oceanography - Elements of marine geology (seafloor topography, acoustical properties of sediments and rocks) - Underwater sound propagation (ray acoustics, ocean noise) - Interaction of sound with the seafloor (reflection, scattering) - Principles of sonar (beamforming) - Underwater acoustic mapping systems (single beam echo sounding, multi-beam echo sounding, sidescan sonar) - Data analysis (refraction corrections, digital terrain modelling) - Applications (hydrographic survey planning and navigation, coastal engineering) - Current and future developments.

This course will begin with brief overview of what important current research topics are in oceanography (physical, geological, and biological) and how acoustics can be used as a tool to address them. Three typical examples are climate, bottom geology, and marine mammal behavior. Will then address the acoustic inverse problem, reviewing inverse methods (linear and nonlinear) and the combination of acoustical methods with other measurements as an integrated system. Last part of course will concentrate on specific case studies, taken from current research journals. This course is taught on campus at MIT and with simultaneous video at Woods Hole Oceanographic Institution.

The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include:

the acoustic cues used in determining the direction of a sound source,

the acoustic and mechanical mechanisms involved in speech production and

the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear.

In this project, each student will be assigned to a group of three to four students. Each group will be given random character description cards. These characters will be treated as the first generation in a fictitious town. The cards will include specific genetic traits, skills, jobs, as well as reference if the character suffers from type 2 diabetes. Students will need to use the character cards to author and illustrate a short story about the fictitious town which follows at least three generations of the families in the cards. Students must also include pedigrees for a minimum of three traits as well as diabetes as evidence of inheritance.

Using the signal transduction pathway for the cholera toxin to understand activation and inhibition.

These worksheets were developed by Bryanne McDonough (PhD Candidate, Boston University) for a 6 week summer AS101 course taught at Boston University using the Openstax Astronomy 2e textbook. Each lesson was two hours long, so modification may be necessary for using these worksheets in a shorter class format, although many are already split into two parts. I'm open to feedback and would love to hear if you decide to use this resource in anyway: please contact Bryanne McDonough (bnmcd@bu.edu).

This article describes covert and overt active engagement strategies for use with elementary students. Find the Question templates are included for use with informational text.

This is a quick and easy to implement active recovery/stretch series to use with a PE class that is sore from a few intense workout sessions.  It could be used for a High School Aerobis Class, Lifetime Activities Class or even a Beginning/Advanced Strength Training Class.

These activities cover topics in Galaxies and Cosmology, aligned with the OpenStax Astronomy textbook. Topics cover chapters 1, 5, 6, 24-30, and sections of chapter 17 and 19 concerning distance. All activities are designed to be done in small groups in the classroom, but most can be adapted for use as homework or projects. Quantitative and Hands-on activities may be used as labs.
