  • 1Ask learners: You want to find information about cocoa farming in Ghana. If you type 'cocoa' into a search engine, you might get results about chocolate bars, cocoa drinks, and cocoa farming. How could you make your search more specific to get only farming information?
  • 2Show on projector: two search results - one highly relevant and one irrelevant. Ask: Why do you think one result is better than the other?
  • UNDERSTANDING SEARCH PHRASES AND EXACT SPELLING
  • 1Open a web browser on the projector. Type 'Lake Volta fish farming' into Google's search bar. Point out that using a complete phrase with correct spelling returns more relevant results than typing single words like 'Lake' or 'Volta' separately. Ask: What difference do you notice in the results?
  • 2Demonstrate typing 'lake volta fsh farming' (with deliberate misspelling). Show learners how the search engine tries to correct it but results are less precise. Explain: correct spelling helps search engines understand exactly what you need.
  • 3Use Ghanaian local context (Lake Volta) to make the search practice relevant and engaging
  • USING AND, OR, NOT OPERATORS FOR EFFECTIVE SEARCHES
  • 4Type into the search bar: 'Ghana cocoa AND farming AND sustainable'. Highlight how AND narrows results by requiring all three terms. Then search 'Ghana cocoa farming'. Ask learners: Which search gave you fewer, more focused results?
  • 5Type: 'Accra OR Kumasi markets'. Show how OR expands results to include either city. Then demonstrate: 'Accra markets NOT clothing'. Explain NOT removes unwanted results - useful when your first search brings up things you don't want, like if Kofi searches for 'mobile money NOT Instagram' to avoid social media ads.
  • 6Demonstrate each operator with live searches using Ghanaian locations and topics familiar to B8 learners
  • 1Computer/Laptop with web browser
  • 2Projector
  • 3Internet connection
  • 4Google Search engine
  • 1Ask three learners to stand. Kofi searches 'trotro'. Ama searches 'trotro AND Accra AND fares'. Abena searches 'trotro NOT bus'. Class discusses: whose search will find the most specific information about trotro fares in Accra?
Exercise
  • 1Write down THREE different ways to search for 'Kejetia Market in Kumasi'. First: use one word only. Second: use a search phrase with AND. Third: use AND and NOT together. Which search is most effective and why?

  • 1Ask: Yesterday we learned to use AND, OR, NOT. But do ALL search engines understand these operators the same way? Let's find out. Show three Ghanaian names on the board: Kwame, Sulemana, Mariama. Ask: If you search for 'Ghanaian traditional names', will Google, Yahoo, and Ask.com all show the same results in the same order?
  • 2Quick poll: Put your hand up if you've used a search engine other than Google. Which one? (Collect 2-3 responses to show variety exists.)
  • COMPARING SEARCH RESULTS ACROSS DIFFERENT SEARCH ENGINES
  • 1Open Google and Yahoo side-by-side on projector. Type the same search string in both: 'Ghana galamsey illegal mining effects'. Take a screenshot of the top 5 Google results. Then show the top 5 Yahoo results. Ask learners to observe: Are the results in the same order? Is the first result the same? Are the websites different?
  • 2Create a simple table on the board: Search Engine | 1st Result | 2nd Result | 3rd Result. Fill it in as you search 'Harmattan weather Ghana' on Google, then Ask.com, then Bing. Ask: Why might different search engines rank the same information differently?
  • 3Use search topics relevant to B8 learners' social context - galamsey, Harmattan - to keep engagement high
  • TESTING SEARCH ENGINE RELIABILITY WITH A MULTI-SEARCH TASK
  • 4Assign pairs: Kwabena and Yaa search 'Susu savings groups Ghana' on Google. Yakubu and Amina search the same phrase on Yahoo. Kofi and Abena search on Ask.com. Each pair records the top 3 result titles. After, pairs report back. Class compares: Did all three engines return relevant results? Which engine seemed most helpful?
  • 5Challenge: Search 'MTN Mobile Money transfer fee 2026' on Google. Then search the exact same phrase on Yahoo. Ask: Did one search engine return more recent/accurate fee information than the other? Why might that be?
  • 6Pair work ensures all learners have hands-on search experience and can compare engine outputs
  • 1Computer/Laptop with web browser
  • 2Projector
  • 3Internet connection
  • 4Google, Yahoo, Ask.com, or Bing search engines
  • 5Whiteboard and marker for recording results table
  • 1Whole class reflection: Today we discovered that different search engines give different results for the same search. Yakubu shares: What was the most surprising difference you found? Mariama shares: When might it be helpful to use more than one search engine instead of just Google?
Exercise
  • 1Search 'Cape Coast Castle history' on TWO different search engines (any two from Google, Yahoo, Bing, Ask.com). Write down the top result title from each engine. Circle which result you think is more reliable and explain your choice in one sentence.

  • 1Display two search results on projector without showing which search engine each came from. Result A is from Google about 'Kakum National Park'. Result B is from Yahoo about the same topic. Ask: Can you tell which engine gave which result just by looking? Why or why not?
  • 2Quick challenge: Kofi needs to find out about Damba Festival. He's not sure if Google or Yahoo will have better results. What should he do? (Expected answer: try both and compare.)
  • INTEGRATING SEARCH TECHNIQUES WITH MULTIPLE SEARCH ENGINES
  • 1Pose a realistic research problem: Abena wants to find information about 'sustainable cocoa farming AND Ashanti Region NOT chemicals'. She will search this phrase on Google first, then Yahoo. Open Google, type the exact phrase. Show the results. Ask: How many results? Are they relevant? Now switch to Yahoo with the same phrase. Ask: Did Yahoo understand the AND and NOT operators? Did the results change? Which engine handled the complex search better?
  • 2Demonstrate a search failure scenario: Type 'chop bar' on Google. Show that results mix chop bar definition, menu ideas, and random websites. Ask learners: This search is too broad. How could we use our search techniques (AND, OR, NOT) AND try a different search engine to fix it? Guide them to suggest: 'best chop bar AND Accra AND traditional food' on both Google and Bing.
  • 3Combine Day 1 techniques (AND, OR, NOT) with Day 2 concept (comparing engines) to show how they work together
  • CONSOLIDATION: LEARNERS CONDUCT INDEPENDENT MULTI-ENGINE SEARCHES
  • 4Assign pairs a topic from this list (adjust to learner interest): Yaa Asantewaa's biography, Tilapia farming in Lake Volta, Mobile money security, or Kente weaving techniques. Each pair must: Search the topic using ONE search technique (AND, OR, or NOT) on Google. Record the top result. Then search the same phrase on Yahoo. Record the top result. Compare: Did they get different results? Which search was more useful?
  • 5Gallery walk preparation: Each pair writes their search topic, the search phrase they used, and their conclusion (Which engine was better? Why?) on a sheet. As pairs finish, they post on the wall. Other learners do a quick gallery walk and read 2-3 other pairs' findings. Ask: Did we all find that one engine is always better, or does it depend on the search topic?
  • 6Independent practice confirms mastery of both indicators - effective searching AND multi-engine comparison
  • 1Computer/Laptop with web browser
  • 2Projector
  • 3Internet connection
  • 4Google and Yahoo search engines
  • 5A3 paper or flipchart sheets for recording
  • 6Markers
  • 1Quick whip-around: Going around the class, each learner finishes this sentence: 'This week I learned that effective searching means.' (expecting answers: using AND/OR/NOT, using phrases, checking spelling, or trying multiple engines). Celebrate responses that show integration of both indicators.
Exercise
  • 1You are helping Fuseini research 'Ghana's renewable energy projects AND solar power NOT wind farms'. Search this phrase on Google. Write down: (1) the exact search phrase you used, (2) the number of results you got, (3) the title of the first result. Now search the same phrase on one other search engine (Yahoo or Bing). Write down the same three details. Finally, write one sentence: Which engine gave you more useful results for Fuseini's research and why?
