  • 3. SEARCH ENGINES
    • Here is a list of commonly used search engines.
      • Google
      • Yahoo
      • MSN
      • Excite
    • Click on the above links to open search engine.
  • 4. How to use search engines
    • Type desired search topic into text box
    • Click on search icon to search topic.
  • 5. Activity 1
    • Use three different search engines to research “states of matter”.
    • In your book, write down the web addresses for the top 3 results for each search engine.
            • Google
            • Yahoo
            • MSN
            • Excite
    • Are the top 3 results on each search engine the same?
  • 6. Improving your search results
    • You can search for a topic that has two terms
    • You can make your search more accurate by using certain joining words, such as AND, OR and NOT
  • 7. Using ‘AND’
    • Using ‘AND’ helps you search for documents that contain both terms. This will narrow the field for a more specific result.
      • For example, states of matter AND liquids
    States of matter liquids Documents including both the terms
  • 8. Using ‘OR’
    • Using ‘OR’ helps you search for documents that contain either of the two terms. This will broaden the field for a wider result.
      • For example, states of matter OR liquids
    States of matter liquids Documents including both the terms
  • 9. Using ‘NOT’
    • Using ‘NOT’ excludes terms from your search, to help your search be more specific. This will narrow the field. (Brackets help to separate the terms.)
      • For example, (states of matter) NOT (liquids)
    States of matter liquids Documents including one term and not the other term
  • 10. Activity 2
    • Using AND OR and NOT, conduct a search using the terms. (don’t forget the brackets for NOT)
        • States of matter
        • Particle model
          • Use Yahoo for your search
    • Your task is to write a description of each state of matter, and use the particle model to help explain your answer.
