Biology is a branch of science that studies living organisms, their structure, function, growth, and evolution. It is an extensive and complex field that encompasses a wide range of topics, from molecular biology to ecology. The International Baccalaureate (IB) Biology Higher Level (HL) curriculum aims to provide students with a comprehensive understanding of the principles and concepts of biology.
In this essay, we will discuss the Internal Assessment (IA) component of the IB Biology HL curriculum. The IA is a scientific investigation that allows students to apply their knowledge and skills to real-life situations. The IA is worth 20% of the student’s final grade and consists of a written report and a presentation.
The IA can be conducted on any topic related to biology, and students are free to choose their own research question. In this essay, we will outline the steps involved in conducting an IA, discuss the criteria used to assess the IA, and provide some tips for writing a successful IA.
Step 1: Choosing a Research Question
The first step in conducting an IA is to choose a research question. The research question should be specific, measurable, and relevant to biology. The research question should also be feasible, meaning that it can be answered within the time and resources available to the student.
A good research question should be focused on a particular area of biology. For example, a research question could be “What is the effect of temperature on the growth of bacteria?” This research question is specific, measurable, and relevant to microbiology.
Step 2: Planning the Investigation
Once the research question has been chosen, the next step is to plan the investigation. The investigation should be designed in such a way that the research question can be answered. The investigation should also be ethical and safe.
The planning stage involves identifying the variables that will be investigated, designing the method, and identifying the equipment and materials needed. The planning stage also involves identifying any potential hazards and developing a risk assessment.
Step 3: Conducting the Investigation
The third step in conducting an IA is to carry out the investigation. The investigation should be conducted in a systematic and controlled manner. The data collected should be accurate and reliable.
During the investigation, it is important to record all observations and measurements. It is also important to keep a record of any problems encountered during the investigation and how they were resolved.
Step 4: Analyzing the Data
Once the investigation is complete, the data collected must be analyzed. The data should be analyzed using appropriate statistical methods. The results should be presented in tables, graphs, and charts.
The data analysis should be used to answer the research question. The results should be discussed in relation to the research question and the hypothesis.
Step 5: Writing the Report
The final step in conducting an IA is to write the report. The report should be written in a clear and concise manner. The report should include an introduction, a methodology section, a results section, a discussion section, and a conclusion.
The introduction should provide background information on the research question and the hypothesis. The methodology section should describe the methods used to conduct the investigation. The results section should present the data collected and analyzed. The discussion section should interpret the results and relate them to the research question and the hypothesis. The conclusion should summarize the findings and their implications.
The IA is assessed using five criteria:
Personal Engagement: This criterion assesses the student’s personal engagement with the research question and the investigation. The student must show evidence of personal engagement and initiative.
Exploration: This criterion assesses the student’s ability to design and plan an investigation. The student must show evidence of a systematic and controlled investigation.
Analysis: This criterion assesses the student’s ability to analyze data using appropriate statistical methods. The student must show evidence of accurate and reliable data analysis.
Evaluation: This criterion assesses the student’s ability to evaluate the results of the investigation and draw conclusions. The student must show evidence of critical thinking and evaluation.
Communication: This criterion assesses the student’s ability to communicate the investigation and the results in a clear and concise manner. The student must show evidence of effective communication skills.
Tips for Writing a Successful IA:
Choose a research question that is specific, measurable, and relevant to biology.
Plan the investigation carefully, ensuring that it is feasible, ethical, and safe.
Collect accurate and reliable data, recording all observations and measurements.
Analyze the data using appropriate statistical methods and present the results in tables, graphs, and charts.
Interpret the results and relate them to the research question and the hypothesis.
Write the report in a clear and concise manner, following the structure outlined in the assessment criteria.
Use proper referencing and citation in the report.
Proofread the report carefully, checking for spelling and grammatical errors.
