Aerodynamics/Birds
Other than wings, what part of the bird also helps with creating lift?
Tail
What part of a shark breaks up the tension in water and reduces drag?
Their skin/scales
What animal often uses hexagons in its homes?
Honeybees
What animal communicates long distances via super low frequency sounds?
Elephants
Name something that makes most birds efficient for flying?
torpedo shape, feathers, hollow bones, wings, tail feathers- any of these
What did scientists use to measure the air currents when a bird flies?
Tiny bubbles
Many fish have a torpedo shape- what does this reduce?
Drag
Why are hexagons most efficient for a hive?
It's the most structurally sound shape and has the most carrying capacity while using the least amount of wax.
Lower frequency sounds travel farther because.....
They can go around trees and rocks without being absorbed.
Name something in nature that utilizes patterns?
(almost anything accepted!)
Imitating the design of birds could help us with what technology?
Mainly airplanes (but other answers accepted such as watercraft or other vehicles)
Viscosity is a fluid's resistance to [________]
A fractal is a pattern that the laws of nature repeat at different scales. IS the pattern being repeated a smaller or bigger version of itself?
Smaller
Sounds below the human level of hearing is called [____]
Infrasonic
Elephants time their communication for these reasons...
Less competing noise, atmosphere/weather that affects how sound travels.
Who was the mathematician that came up with the theory about lift and air currents?
Bernoulli
Fish like Puffer Fish and Rays who use their front fins for the main production of movement need this adaptation because....
they need to maneuver in tight spaces and be able to have agility vs. speed
Alan Turing (who cracked the German code in WW2) came up with a theory about how patterns in nature are formed. What was his theory?
Dueling forces have "on" and "off" switches that create things like digits, stripes, and patterns in nature.
The "secret" infrasonic communication elephants use was discovered by Katharine Payne at this location...
Oregon Zoo
This sequence is the mathematical explanation for things like shells, radial flower petals, pine cones, etc.
Fibonacci Sequence
When air above a wing gets compressed and moves quickly, and air below widens and slows down, this creates [____]
Lift
What official event had to ban shark-imitating suits because it was considered "technological doping"?
Olympic Swimming
Joseph Plateau studied angles: When you put 4+ bubbles next to each other, what angle is formed?
120 degrees
Elephants are VERY loud- they communicate around 117 decibels- the same level as: [______]
Construction Equipment or a Live Rock Band
Name an animal that can hear wider ranges than humans.
Rats, mice, cats, dogs, bats, whales/dolphins, etc.
