Sonar Demonstration -- Human Sound Wave
Kent Syverson, University of Wisconsin-Eau Claire
Sonar technology allowed scientists to produce high-resolution maps of the sea floor for the first time. This sonar demonstration uses a Human Sound Wave to image the "sea floor" in a lecture hall. In ...

Introduction to circuits and Arduino coding
Lauren Sahl, Maine Maritime Academy; Barbara Fleck, Maine Maritime Academy; Sarah O'Malley, Maine Maritime Academy
This activity guides students through making a simple circuit and writing a simple Arduino sketch (code) to make some LEDs blink. It precedes a lab where students build a temperature sensor, and could be used prior ...

Earth's Magnetic Field CogSketch geoscience worksheet
Bridget Garnier, Blue Valley School
Sketching activity that uses a sketch-understanding program, CogSketch. To draw attention to the changes in magnetic inclination with latitude on Earth, students move, rotate, and match packages of "rock" ...

Wave Interference
Glenn Richard, SUNY at Stony Brook
This activity engages students in the exploration of interference between sinusoidal wave forms. They use an interactive applet to manipulate the phase, wavelength, amplitude, and phase velocity of two waveforms ...

Discovering New Worlds
Dora Kastel, New Visions for Public Schools
This resource is a set of student and teacher materials for a new NGSS-driven Earth & Space Science (ESS) unit (4-6 weeks of instruction). The anchor phenomenon students are exploring through modeling and data ...

Slinky and Waves
This physical model presented by Jeffrey S. Barker, Associate Professor of Geophysics, Pennsylvania State University. Starting Point page organized by R.M. MacKay.
Use a Slinky to show:P and S waves, Wave reflection, and Standing waves in interactive lecture demonstration. -

Lab 5: All About Air Pressure
John McDaris, Carleton College
The lab activity described here was created by John McDaris of SERC for the EarthLabs project. Summary and Learning Objectives Students select a storm from the HURDAT database and create its track in the ...

A short lecture on evaluation of Complex integrations for Geophysics
Avradip Ghosh, University of Houston-University Park
In Geophysics, we heavily use Fourier/Laplace, or inverse Fourier/Laplace transforms in all branches. Anyone who has tried to evaluate them using pen and paper (especially an inverse Fourier/Laplace transform) ...

Visualizing Sun Position of the Seasons
Chris Sinton, Ithaca College
The goal of the exercise is to help students visualize and better understand how the sun changes apparent position over the course of the seasons.

Conceptest: Equator tilt
David McConnell, North Carolina State University
What would happen to the average temperature at the equator during our summer if the tilt angle of Earth's axis increased to 27 degrees? A. Temperatures would increase B. Temperatures would decrease C. ...
