http://www.longwood.k12.ny.us/wmi/wq/collin/index.html – page is not found

so we went to http://www.longwood.k12.ny.us and find “WMI.” Then we went to http://www.longwood.k12.ny.us/wmi/ but couldn’t find anything about Shakespeare.

We tried different ways such as http://www.longwood.k12.ny.us/wmi/wq , http://www.longwood.k12.ny.us/wmi/wq/collin , and http://www.longwood.k12.ny.us/index.html but still couldn’t find about Shakespeare.

Then we searched the site in Google, and we had this page with the name “Untitled Document”. Finally we found the site that shows the information about “Romeo and Juliet” by Shakespeare.

We searched http://www.ssischool.org/ in find pages similar to the page and the information that we had were about other international schools in Vietnam and about Phu My Hung. The numbers of hits were about 27. When we searched http://www.ssischool.org/ in find pages that link to the page, we had 4 hits and information about SSIS, UNI Overseas Recruiting Fair, and about Vietnam.

What I learned from google search is that if we use google advanced search, we can find the accurate information faster. Moreover, while I used  adcanved google search, I learned some signs too. For example, if there are unwanted words, you can use negative sign (-) to get rid of that word.

Another fact that I learned is if the page is unfounded, I can search that site in google and find that site.

Lastly, I learned how to find similar pages and the page that links to. From now, I can research more accurately and easily…

My element is silver. Atomic number of silver is 47. It’s solid and metallic. It does not have exact discovered place but it is mostly found in China. The symbol came from the Latin word argentum. There are 47 protons and electrons and 61 neutrons. Pure silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable. Pure silver has the highest electrical and thermal conductivity of all metals.

The fact that 45% of population are living with under $2 impact on me.  I did not know that much people are in poor condition. Also, they die because they starve… they don’t have any food to eat. I realized importance of the food. Moreover, I felt that they really need help from other people.

Finally, I learned that I can help poverty people even I am a teenager. When I grow up, I will be a doctor and I will provide help to them…
