Presentations

Reaction Action Other Presenters: Daniel Reed, Luke Cherniack, Erin Goodwin

Action Reaction is a presentation centered on how the basics of chemical reactions can be applied to engineering. The basic principle of a chemical reaction being a rearrangement of atoms is explained using the formation of water molecules. Then, the five key signs of identifying chemical reactions are introduced with video demonstrations of each. For the hands on activity, the “elephant toothpaste” reaction is introduced. It is a safe reaction involving dilute hydrogen peroxide decomposing to air and water with an iodine catalyst. Doing this reaction in the presence of dish soap creates a column of foam. The students then preform this reaction, making a tall column of foam. Finally, presenters explain how reactions like this are used in all branches of engineering to help improve the world.

Digital Sound Other Presenters: Timothy Spafford, Brook Rulewich, Nickolas Ziter, Mallory Gordon, David Glowny, Denver Overend, Liam Fahey, Casey-Ellen Collette, Amy Reynolds

People rely on the engineering behind the science of sound everyday, whether its through listening to an Ipod, setting up speakers for a public event, or even through hearing aids. And yet, in this digital age, it is not clear to many people how exactly sound is stored in a digital device, what sound actually is, and how sound can be produced electronically. Therefore, this presentation displays and explains the intriguing engineering behind sound and its application in electronic devices.

Solar Energy: The Future of Residential Power Other Presenters: Daniel Reed

This presentation gives an overview of energy flow and conversion and applies these concepts to solar power. The presentation gives an elementary explanation of how photovoltaic cells and takes a peak at what's new and upcoming in the exciting field of solar power.

Thermoelectric Devices Other Presenters: Leili Tootsov, Casey-Ellen Collette

Learn about how to convert heat into electricity! This presentation covers the basics of efficiency, energy usage, energy conversion, and power, and walks students through the materials science behind thermoelectric devices. Students also experiment with their own thermoelectric devices and produce electricity to power propellers.
