This is an opportunity to explore occurrences of parabolas in the world around us.
Parabolic shapes in the real world
According to Wikipedia, that great internet source of both information and misinformation, "In nature, approximations of parabolas and paraboloids are found in many diverse situations."
Research ONE example of a parabola in real life that has not already been used by a classmate.Tell us in your own words about your parabolic find (at least 150 words). Do not just make this up off the top of your head. The St Louis Arch, for example, is NOT a parabola—it is an inverted catenary.
To get credit for this Forum, you must cite a source confirming that your example is, indeed, parabolic and not some other more exotic curve. Using a personal example (My eyebrow) will not count unless you can cite a source verifying that eyebrows are parabolic.
Please, DO NOT use examples listed below:
Roller Coasters, Ballistics, Angry Bird Parabola, Parabolic Microphones, Golden Gate Bridge , Path of an Object, Car Headlights, Fountain at Detroit Airport.
