Selecting search results
Lesson details
Learning outcome
I can describe how search engines select results.
Key learning points
- Search engines are tools, which help you find things online.
- Web crawlers are used to create a search engine's index.
- Search engines look up search terms in indexes.
Keywords
Search engine - a tool that finds websites based on the search term used
Index - a list that helps find and organise information quickly
Web crawler - a program that visits websites and collects information to help create a search engine’s index
Common misconception
When you use a search engine, it checks every website in the world before coming back with a result.
A search engine just searches its index to find the relevant results.
Teacher tip
When discussing searching for things online, it is important to remind children of online safety rules. Make sure that you test some of your search results before the lesson, to ensure that results are appropriate.
Equipment
It might be useful to show a physical encyclopedia to compare with a search engine
