The National Geographic Society. National Geographic website Essay

The National Geographic Society. National Geographic website - Essay Example The beautiful animals illustrated in the website connect the viewers of the website with nature. At the top of the website there are eight primary links that allow the users to visit different parts of the website. The eight primary links are photography, animals, environmental, travel, adventure, nageotv, kids, and video. The photography section has lots of different pictures of animals, nature, landscapes, among other things. The kids section has educational games children can play. The travel section has images and information about the cultures of different parts of the world. Below the primary links at the top there are secondary links in yellow. The secondary links take the users to different segments of the website. The secondary links are daily news, the magazine, maps, science, education, games, music blogs, movies, in the field, mobile, and newsletters. The daily news segment has lots of interesting articles. I read an article that stated that being bilingual delays aging effects. In the maps section there are different interactive 3D maps of the world. The magazine link has the current issue of the National Geographic magazine for the month of March 2011. The issue can be read online free of charge.

The Experiment That Use Heat Loss plus Heat Gain of a Given Substance Lab Report

The Experiment That Use Heat Loss plus Heat Gain of a Given Substance and Also the Given Phenomenon of Specific Heat in the Laboratory - Lab Report Example The paper tells that a mass of a given metal block got weighed then a piece of twine like 30 cm long became attached to it. Then the block became lowered into a steam boiler. The boiler then had half filled water.   As the water got heated to boil, the mass of an empty calorimeter got measured. The calorimeter got filled two-thirds with water that was several degrees colder compared to room temperature. Then the mass of both water and calorimeter became measured. In the experiment, an outer cap became placed around the calorimeter to prevent heat loss from it when it becomes warmer than room temperature. In the experiment, the two metals used became copper and Iron. The mass of copper and iron became 269.53g and 230.80g respectively upon weighing. The mass of calorimeter used became 46.13g. The mass of calorimeter added water for Iron was slightly more than that of copper. In starting with an original temperature for the calorimeter plus water at 21.9 degrees, in dipping the blocks of metal, the final temperature dipped with copper became 30.4 degrees while for iron became 30.1 degrees. In calculating the specific heat of solid for the two experiments, an error of 0.006cal/g-degrees became found for copper while an error of 0.003cal/g-degrees became recorded for Iron. Therefore, iron recorded a percentage error of 2.86% from the accepted value while copper recorded a percentage error of 6.45%.
