Biodiversity

Grade 10 · Science · Free lesson

Hey there! Ready to level up your science research skills? Let's explore how asking the right secondary questions can help you refine your main research topic!

When we study biodiversity, we look at the amazing variety of life on Earth. To research this topic deeply, we must start with a major research question. However, our first question is often too broad to answer easily.

To improve our main question, we use a secondary set of smaller, guided questions. These smaller questions help us gather specific facts. We can then refine our original question to make it much stronger and more focused.

Major QuestionSecondary Q1Secondary Q2

For example, if we ask 'How does biodiversity help an ecosystem?', we need secondary questions to narrow it down. We can ask about a specific habitat, like a local pond, and a specific threat, like a new building project nearby.

Focused Habitat: Local Pond Ecosystem
✏️ Worked example

Imagine you start with this broad research question: 'How do human activities affect forest biodiversity?' Walk through the steps to refine this major research question using a secondary set of questions.

  1. Identify the broad terms in your starting question. Here, 'human activities' and 'forest biodiversity' are very large topics that cover too many different ideas.
  2. Create a secondary set of questions to gather specific details. For example: 'Which specific human activity is most common in our local forest?' and 'Which local forest species are most sensitive to changes?'
  3. Answer your secondary questions with basic background research. You find that trail construction is the main activity, and local songbirds are the most sensitive species.
  4. Use these new details to refine your major research question. Combine the specific activity and the specific species into your final, polished question.
  5. State your refined research question clearly: 'How does walking trail construction in Oakwood Forest affect the nesting patterns of local songbirds?'
