Today, we are talking about the importance of a research question in your Internal Assessment. The research question is not just a formality; it's the cornerstone of your entire investigation.
Why is it so important? Can't we just start experimenting?
Great question! Without a well-defined question, your experiment may lack focus, making it difficult to draw meaningful conclusions. A strong research question guides your entire process.
What makes a good research question then?
A good research question should be focused, specific, investigable, and relevant to chemistry. For example, instead of asking about reaction rates in general, we could ask: 'How does temperature affect the rate of the reaction between sodium thiosulfate and hydrochloric acid?' Can someone tell me what makes the second question better?
Itβs more specific and focused on one aspect of chemistry!
Exactly! It allows for a targeted investigation. Remember, a specific question leads to a better exploration. Let's summarize: focused, specific, investigable β these qualities help ensure a meaningful experiment.
Brainstorming Research Questions

Now let's discuss brainstorming your research questions. Start broad with an area of interest in chemistry. For example, kinetics, acids and bases, or organic synthesis.
How do we narrow it down from such a broad area?
Good point! Once you identify an area, think about what independent and dependent variables you can work with. This helps clarify your focus.
Like changing the temperature in a reaction?
Yes! For instance, you could investigate how changing the temperature affects the speed of a reaction. So now, how would you write a potential research question based on that?
Maybe, 'How does increasing temperature affect the speed of a chemical reaction?'
That's close! Try to specify the reaction and conditions, like: 'How does temperature affect the rate of the reaction between sodium thiosulfate and hydrochloric acid?' Itβs important to be clear and specific.
Assessing Research Questions for Feasibility

After formulating a question, the next step is to assess its feasibility. This involves ensuring you have access to the necessary resources, equipment, and safety protocols.
What if I think my question is too complex?
That's a valid concern. If a question requires advanced equipment or techniques beyond what is available, it's wise to refine it further for practicality.
How do I ensure I pick a question I'll be engaged with?
Excellent question! Choose a topic that genuinely interests you. Personal engagement can significantly enhance the quality of your investigation. Remember, your curiosity will shine through your work!
So if I connect my research to a real-world application, it might help?
Absolutely! Real-world applications make the work more meaningful. In summary, ensure your question is feasible, safe, and personally engaging for the best results.

Detailed
Choosing a Research Question
The research question is foundational to the Internal Assessment (IA) in the IB Chemistry curriculum. A well-crafted question functions as a guide for the chosen investigation. Key qualities of a good research question include being:
- Focused: The question should address a specific chemistry topic rather than a broad one. For instance, rather than asking 'What affects reaction rate?', you might ask, 'How does temperature affect the rate of the reaction between sodium thiosulfate and hydrochloric acid?'
- Specific: Clearly outlines the variables involved in the inquiry.
- Investigable: It must be answerable through experimentation with available resources, avoiding both overly simple and exceedingly complex queries.
- Relevant to Chemistry: The question should align with the IB Chemistry syllabus.
- Leads to Quantitative Data: Ideally, it allows for the collection of data suitable for statistical analysis.
- Allows for Depth of Analysis: A good question uncovers relationships or trends that can be explored in detail.
To assist in formulating a good research question, the section suggests a brainstorming approach, beginning broadly within the chemistry syllabus, then narrowing down to specific variables (independent, dependent, and controlled). After refining the question, students are encouraged to assess resources and safety considerations to finalize their inquiry, ensuring personal engagement and genuine interest in the topic.

The research question is the cornerstone of your IA. A well-formulated research question is focused, specific, and investigable.
Detailed Explanation
The research question serves as the main inquiry of your Internal Assessment (IA). It is crucial for guiding the entire scientific investigation because it defines what you will explore. A strong research question will be narrow enough to be manageable yet broad enough to allow exploration. You need to ensure that it can be answered through practical experimentation.
Examples & Analogies
Think of the research question as a compass for a journey. Just as a compass points you in the right direction, a well-defined research question directs your investigation, helping you stay focused on your goals and avoid wandering off into unrelated areas.
Qualities of a Good Research Question

Qualities of a Good Research Question:
- Focused: It addresses a specific aspect of chemistry rather than a broad topic.
- Specific: It clearly defines the variables involved.
- Investigable: It can be answered through experimentation using available resources and within the given timeframe.
- Relevant to Chemistry: It clearly falls within the scope of the IB Chemistry syllabus.
- Leads to Quantitative Data: Ideally, it should allow for the collection of numerical data that can be analyzed statistically.
- Allows for Depth of Analysis and Evaluation: A good question will reveal relationships, trends, or underlying principles that can be explored in detail.
Detailed Explanation
A good research question possesses several important qualities: it should be focused on a specific topic rather than a broad one; it needs to clearly define the variables you are studying, like independent and dependent variables; and it must be investigable with the resources you have. Furthermore, it should relate to chemistry concepts covered in the syllabus. The question should ideally allow you to gather quantitative data, which means you can analyze it statistically. Finally, it should be structured in a way that allows for detailed exploration of concepts, trends, or principles.
Examples & Analogies
Consider a good research question as a recipe in cooking. Just as a recipe provides specific ingredients and steps for creating a dish, a focused question outlines exactly what you will explore. For example, asking, 'How does temperature affect the cooking time of pasta?' is much more precise and manageable than simply asking, 'What happens when you cook pasta?'
Brainstorming and Refining Research Questions

Brainstorming and Refining Research Questions:
1. Start Broad: Identify an area of interest within the chemistry syllabus (e.g., kinetics, acids/bases, organic synthesis, electrochemistry).
2. Identify Variables: For your chosen area, think about what independent variables you could manipulate and what dependent variables you could measure.
- Independent Variable: What you change (e.g., temperature, concentration, surface area, type of catalyst).
- Dependent Variable: What you measure (e.g., rate of reaction, pH, mass change, volume of gas produced, absorbance).
- Controlled Variables: What you keep constant to ensure a fair test (e.g., total volume, stirring rate, purity of reagents, pressure).
3. Formulate a Question: Phrase your question as a clear, interrogative sentence.
- Initial idea: "Acids and bases."
- Refinement: "How does the concentration of a weak acid affect its pH?"
- Further refinement: "How does varying the initial concentration of ethanoic acid affect the equilibrium pH of its aqueous solution at 298 K?" (This is specific, includes a controlled variable, and clearly defines the scope).
4. Consider Resources and Safety: Before finalizing, ensure you have access to the necessary equipment and chemicals, and that the experiment can be conducted safely within school guidelines. Conduct a preliminary risk assessment.
5. Personal Engagement: Choose a topic that genuinely interests you.
Detailed Explanation
The process of developing a research question begins with brainstorming ideas. First, consider what intrigues you about chemistry and select a broad topic from the syllabus. Next, pinpoint the specific variables you wish to explore: identify what you will change (independent variable) and what you will measure (dependent variable), while keeping control variables constant for a fair test. After that, phrase your question clearly, refining it as needed to make it specific and focused. Ensure you have the resources and safety measures in place to conduct your investigation, and choose a topic that genuinely excites you, as personal interest will enhance your engagement and the quality of your results.
Examples & Analogies
Imagine youβre planning a road trip. You start by deciding a general direction (your broad topic). As you plan, you figure out what stops you want to make (variables) and consider how long and well-maintained your vehicle is (resources and safety). Finally, you map out your route (refined question), ensuring it leads to interesting destinations, which would keep you motivated and engaged during the trip.
