Amelia Earhart

On the lunar eclipse night of Tuesday, August 28, 2007, there was a presentation of the collected data of the fallen pilot - Amelia Earhart, where from NMC after the whole car pooling incident, we were able to watch paint dry once more. The presentation was very informative, providing much information of the American pilot that disappeared over the Pacific. The presentation consisted of several materials that were found from a plane wreckage along with tools that was used to pry open clams, which was believed to be used by Amelia Earhart. At the same time of listening to the presentor, I strayed off from the time and ran out to find that the clouds have covered the moon =.= ...really nice. *sigh* I headed in afterwards to learn more about the new found evidence where they continued on with the comparisons of plane wreckages and the plexi-glass. Besides the whole plane wreckages, modifyied tools, and clams. I got to see a pig get eaten up by strawberry hermit crabs!! Woohoo!! That was cool! but it was only the before and after views. :(

Lunar eclipse

The lunar eclipse, which was blocked by the clouds at one time, was completly visible upon exiting the museum, and was too cool!! Obtaining the blood red - orange color due to the sunlight refracting off of the Earth's surface, "it lasted for about 90 minutes"(Saipan Tribune).

this is the eclipse that i saw on August 28, 2007

Tides


a. What is a tidal range?
A tidal range is the difference between high and low tides.

b. What causes high and low tides?
Tides are caused by the gravitational attraction of the Moon and the Sun as well as the rotational velocity of the Earth, producing a centrifugal force that balances the gravitational attraction between the Earth and the moon, causing great bulges of water to appear. A high tide then occurs when the point is under a bulge and a low tide occurs when the point of the Earth is away from the bulge.

c. What causes Spring and Neap tides?
A spring tide, occurs twice a month throughout the year when the Sun/moon/Earth are in line; resulting in a very big tidal range, thus marking a larger gravitational attraction. Whent he Sun/moon are at 90 degrees to each other, a neap tide results, occurring during the first and last quarter moons.

d. How does tidal range effect the types of organisms and the shape and size of the organisms?
Based on the type of tidal range that an area experiences, it may then be justifiable to state that the diversity of organisms which may inhabit the tidal zones must be able to succumb to the changing tides as the high and low tide markers are the most violent zones - in terms of the energy being released in that area (the crashing of the waves), the amount of food, as well as the endurance of the organism(s) when exposed during low tide. The variety of organisms which would most likely inhabit these areas would range from several types of shellfish, crabs, and vegetation.
