This activity is a unique and engaging way to introduce students to sound waves and wave basics. Using Google Earth (a free download), students will travel to the following eight stops: 1) Virginia Tech, Vibrations and Acoustics Lab 2) NOAA Sound Garden, Seattle WA. 3) Krakatoa, Indonesia 4) Bracken Bat Caves, San Antonio TX. 5) Cedar River Watershed, North Bend WA. 6) Chile, South America 7) Sumatra, Indonesia and 8) Oregon State University, Wave Lab.
Each of the stops has a pop up box of information that includes images, text, stop questions and links that guide students to new understanding of waves. Links can include reading, interactive on-line simulations, games, infographics and video clips.
The topics addressed at the stops include: wave structure, frequency, sound traveling through different mediums, measuring sound using decibels, comparing/contrasting echolocation and sonar, relating volume and amplitude/pitch and frequency, looking at seismic waves/longitudinal vs. transverse waves and tsunamis - engineering for protection, current research and early warning systems.
This is intended to be an introduction to waves and sound. Students do not need to have any background instruction prior to this activity.
The activity should take 1-2 class periods. This activity is designed for a 1-to-1 environment. Please make sure that each student completing the activity has internet access and Google Earth installed on their device.
