Grade 12 Project (Grouping 10-12)
Team Members: Mildred Lau, Mo Zhang, Paul Sedach (3 Members)
Subject Area: Physics
Project Type: Experimental
Project Level: Advanced
Project Format: Traditional
Summary: The project was designed to show how sound traveled through different substances and then equate this to how sonar causes damage to whales underwater. Various chemicals in liquid, solid and gas phases were compared to each other at the same temperature and to themselves at different temperatures. The chemicals were chosen on the basies of their chemical formula, structure, atomic mass, and amount of differing amount of valence electrons. These results were then used to show how and why aquatic life (specifically whales) are more affected by sound in water than those creatures that are above ground.
Software Tools used: Macromedia Dreamweaver MX, Notepad, and Useful File Utilities Batch Replacer were used for putting the web page together. Adobe Photoshop, Corel Draw and Microsoft Excel were used for the graphics and graphs.
Hardware Tools used: Hand Saw, Drill, Screwdriver, Jig Saw, Refrigerator, Stove, CanoScan FB630P Scanner, Athlon 2000+ computer, FujiFilm FinePix 2400Zoom Camera, Altec Lansing Speakers
Source of the Idea for the project: After a recent program on CNN about the deaths of whales (to draw attention away from the war in Iraq) to SONAR, we decided it was an awesome idea for us to put to use in Group 4 (you've got to have it in all three areas) as it had to do with physics, chemistry, and biology (but mostly physics - we're all physics students...)
Special Skills used to build the project: Some small amount of html and Java Script, hand tool skills
Awards won for the project: None yet
This project has been put up for Canada's Virtual Science Fair:
