The Internet is a Huge House of Candy
The Internet is a bag of “Every Flavor Beans”
Imagine that the Wooden Rollercoaster drops you off at the amazing "House of Candy!" You land at the front door of this huge structure and see that it stretches thousands of stories high into the sky–so high that you can’t see the top floor!
You walk through the front door and meet the sales clerk, Ms. Cand E. Barz, who explains that every floor contains millions of different kinds of candy. She points to a sign that reads: FREE CANDY - ALL YOU CAN EAT! and explains that the owners add more and more floors to the "House of Candy" every single day, with new and different varieties of candy to taste.
"The building stretches up through the clouds and on to the edge of space!" explains Ms. Barz. "It’s up to you to figure out how to get to the floor that has your favorite candy. Be careful what you taste. Not all of the candy is sweet. Some of it is very sour and some of it is too old to eat. Goodbye and good luck!"
Ms. Barz disappears and leaves you standing there on the ground level, drooling and wondering how to find those nutty crunchy chocolate bars you like so much. You don’t see an elevator or set of stairs anywhere in sight. Yummmm…so much candy and so little time! What’s a kid to do?
The Internet can be compared to the imaginary "House of Candy." Many times, when you connect to the Internet, you need to find the answer to only one question, but you soon discover that the amount of information is so huge that you don’t know where to start or how to find it. Furthermore, you know that information on the Internet continues to grow and change every minute of every day! And as you learned a few weeks ago, you can’t believe everything you see on the Internet. What’s a cool fifth grader like you to do in a situation like this?
How does a search engine help you find the good ‘candy’ or good websites? ______

A search engine is just like a sorting machine. It can sort out the good and the bad web pages and leave the bad ones at the bottom, just like a sorting machine would leave the bad candy at the bottom of a bag.
Do all search engines sort websites the same way? Yes No
What influences how they are sorted? ______
______
______
How can you make the sorting machine or search engine pull up better websites? ______
The First Piece of Evidence
Search Engine Features
How does a SEARCH ENGINE work?
Search engines use a computer program called a spider to roam the World Wide Web exploring Web pages and their links. The spider collects information and then a second computer program indexes all the information. Each search engine’s spider and index organizes Web pages a bit differently.
Search engines also have a third computer program that actually goes into the index to find matches between your keywords and Web pages. The sites with the best matches are displayed first. Each search engine has a different way of identifying the best sites. This is why you are very likely to get different results from different search engines. These three tasks are all done without any human involvement— so a huge number of sites are indexed quickly.
Directions: We will investigate three search engines: Google, Yippy and Bing. With a partner you will be assigned just ONE of these features. You need to start with Google and write a definition explaining WHAT your feature is and what it does. In the notes section below, answer the questions and note what you can show your classmates next week. You should explore this feature on Yippy and Bing as well to see how it works on each site.

The Second Piece of Evidence
Search Engine Results
Read: Just think! Every major search engine has information about millions and millions of World Wide Web sites. At the click of a button, a search engine sorts through what it "knows" and lists the sites it "thinks" you want. In some ways, a search engine is like a well-trained dog. It will fetch what you want, but only if you use the right commands.
More Words Are Better
While single words are better commands for dogs, more words are better for search engines. A search for a single word may “fetch” a million sites. Obviously, it’s tough to check a million sites to find the best one for your needs. Adding more words fetches fewer sites that are closer to what you need.
Let’s say your teacher tells you to find out whether the element mercury is toxic. Start by typing in mercury in Google and hitting the enter key.
How many web pages were retrieved? ______
Look over the description of the first few sites. What are they about?______
------
By now you may realize that the word mercury has more than one meaning. Try adding another word to tell what about mercury really interests you. Type in mercury element. How many Web pages were retrieved? ______
Look over the description of the first few sites. What are they about?______
------
Although these sites might have the answer to your question, they might not. Now try adding a third word. Type in mercury element toxic. How many Web pages were retrieved? ______
Look over the description of the first few sites. What are they about? ______
Looking at the Numbers
Compare the number of web pages retrieved for the three searches. What do they tell you about how the search engine does its work?
______
Looking at other Search Engines
Now let’s try that again at another search engine. Go to www.yippy.com

Third Piece of Evidence
Motive
Read: Search engines rely on specialized software programs that periodically visit (spider) the Internet, and locate key words on each web site. Those key words are then cross referenced with the web site location. The searcher accesses the search engine results at various locations, types in the key words for their search, and the results are shown from this cross reference.
There are a number of problems with search engines and the results they offer:
· Search engines simply cannot keep up with all the changes that occur and the new web sites that are built every day. Links are often out-dated
· Web site builders may include key words in their site for the benefit of the spider software that have nothing to do with the true content of the web site itself.
· There is a big business selling web site builders methods of tricking the search engines to get their web site higher in the search results. This may mean that the best sites are not always in the top group of those shown.
MOTIVE: ______
