While Google, Bing and Yahoo dominate (居……之首) adult search engine choices, they are not always the best choice for students. The sites on this list are good search engines that students can rely on.
Fact Monster
Homework help is always on hand with Fact Monster (www. factmonster. com). It is mainly fit for students aged from 7 to 12. There are also all kinds of games, spelling tests and more for kids to improve their study and have some fun.
Ask Kids
Ask Kids (www. askkids.com) is a great site for students to safely find the information they need from the web. Besides being a useful and safe search engine, Ask Kids also has a useful picture and video search function that allows students to find pictures or videos that may be useful to their information search.
SortFix
SortFix (www. sortfix.com) is one of the useful search engines for students because it provides relevant, organized search results. It does this by analyzing the keywords in the search results, and giving the searcher the ability to focus on, or remove, certain keywords. It is a useful search engine if you are not sure what information you want to find, or if you are tired of finding irrelevant results in your searches.
Wolfram Alpha
Created by Stephen Wolfram, Wolfram Alpha (www. wolframalpha. com) can calculate things that it would take a hundred or more individual websites to do. It uses a set of ways to answer questions directly that you type into the search box, which is different from other websites. You can find everything from the nutritional value of an apple to the real-time position of the International Space Station. An Apple app is offered so that you can add it to any iPod Touch devices. It is best suited for older students.
