The Waves and Tsunamis Project
, Woods Hole Oceanographic Institution
How is a tsunami like a wave on a string? We assemble rubber bands, paper clips and washers into strings with various mass distributions to observe the effects on wave characteristics. The project is supplemented ...

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" ...

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 ...

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 ...

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 ...

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.

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) ...

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. ...
