I-05-1: Zachary Taylor: the 12th president ; ballon event in Philadephia So, as Jim said, James Polk was the 11th president,and my report was (is about) the next president, Jack reteller, was elected in 1849.
It was surprising, because he was the first president that didn't have any previous political experience. The main reason he was chosen as the candidate was because he was a war hero. In the army, his main cordorma old ruffian ready(man called him old rough and ready). I guess
because it's a raff edgies(rough edges). He was kind of blonde(blunt), and didn't really look like a military hero. He like to do things,like wear serving (civilian)clothes instead of(and set of)
a uniform, even in battle. And he is so short and plump(blonde) that he had to be lifted to (be happy to live )up to his horse. But he didn't went(did win) a lot of battles. He became more and more popular.So the victor(whig) party decide to nominate him for the presidency, even no one knew anything about where he stood on the issues.
I couldn't find much about the accomplishments. Probably because he was
only an office about a year and a half before he died. But, one thing, he pushed for the development of transcontinental railroad, because he think it was important to form a link with the west coast. The were a lot of welfare (wealth) in California and Oregon from comers(commerce) and mineral and stuff. Also he established an agriculture bureau in the Department of the interior and promoted more government aid to agriculture. Well, that's about all I found. Like I said, he died in office in 1855(1850). So, it was(his) vice president took over. That's the next report. So, thank you. I-05-2: ballon event in Philadephia Listen to a talk in a special event:
I want to welcome each at(and) a every ballon enthusiast to Philadephia. Thank you for coming here this morning to commomerate the first balloon voyage in the United States. On Jan 9th,1793,at 10 o'clock in the morning, a silk(sealed) balloon lifed into the sky above the city, which was at the time the capital of the country.
According to the original record of the flight, the voyage lasts 46 minutes, from departure of Philadephia to its landing across the Delervier river in New Jersey. Though our pilot today will try to approximate the original landing site,
they are at(there is) the mercy of the winds. So, who knows where their(they'll) drift off to?
Even the balloonists(Brunals) in 1793 experience some
un(one)certain weather that day, there was clouds, fogs and mist in various(every) directions. Our enactment promise to be nothing less than (unless) the spectacular. The yellow balloon directly behind me is 5 stories high. It's inflated with helium,unlike the original which was filled with high hydroeon(oxygen) and unbeknownst (aren't be known) to the pilot potentially explosive.
Gas filled models are pretty(put) uncommon now because the extremely high cost. So the eighty other ballons in today's launch are hot air(there), heat by propane(propeling) burners. These ballons are from all over the country. I am glad you brought up the question of our investigation into the make up of the earth interior. In fact, since this is the topic of your
reading assignment for next time, let me spend the last few minutes of the class talking about it. There were several important discoveries in the early(yearly) part of this century that help geologist develop a more accurate picture of the earth interior. The first key discovery has to do with seismic waves. Remember, they are the vibrations caused(called) by earthquake. Well, scientists found they travel thousand of miles
through the earth interior. These founding enable geologists to study the inner part of the earth. You see, this study revealed(review) these vibration were two types; compression, or P waves, and shear(sheer) or s waves.And researcher found p-waves travel both liquids and solids while s-wave travel only solid matter. In 1906,a British geologist discovered P-waves slow down at a certain depth but kept traveling deeper; On the other hand, s-wave either disappear or were reflected back. So he concluded that the depth marked(might be) the boundary between a a solid mantle and a liquid core. Three years later, another boundary was discovered that between the mantle and the earth crust. There're still a lot to be learned about the earth. For instance, geologist know the core of the earth is hot. Evidence is the molten lava flow outside of
the valcano. But we are still not sure what the source of the heat is?
