Biology in Practice Investigation (LC 2027) (Leaving Cert Biology): Revision Notes
Biology in Practice Investigation
What is the Biology in Practice Investigation?
The Biology in Practice Investigation is a major component of your Leaving Certificate Biology course, making up a substantial 40% of your overall grade. This investigation is based on a common brief that the State Examinations Commission (SEC) releases each year, and you'll complete it during your second year of study.
This investigation gives you the opportunity to work like a real scientist, connecting classroom learning with practical research skills that professional biologists use in their daily work.
The three main components you must complete
1. Scientific research
Your first task involves conducting thorough background research on the topic outlined in the brief. This research phase requires you to:
- Investigate the issue presented in the annual brief thoroughly
- Use secondary sources such as textbooks, scientific articles, and online databases to gather information
- Process and evaluate the information you find to understand the scientific context
- Use this research to inform and guide your experimental design
Think of this as building the foundation of knowledge you'll need before you start your practical work.
2. Experimental work
The practical component forms the heart of your investigation. During this phase, you need to:
- Develop a clear hypothesis based on the issue and your background research
- Plan and design a well-structured experiment that tests your hypothesis
- Collect primary data through careful investigation and observation
- Analyse your results systematically to identify patterns and trends
- Draw evidence-based conclusions from your findings
Your experimental design should be thorough, accurate, and demonstrate good scientific methodology. This is where you'll spend most of your practical time and effort.
3. Final report
The culmination of your work is presenting your findings in a comprehensive report that:
- Presents an evidence-based argument in response to the original brief
- Follows the specific format set out by the SEC
- Demonstrates clear links between your research, experimental work, and conclusions
- Shows your understanding of how your investigation relates to real-world biology
How you'll be assessed
Examiners evaluate your work across four key areas, each with different achievement levels:
Knowledge and understanding
This assesses how well you grasp the biological concepts involved in your investigation.
- High achievement: You demonstrate deep understanding of concepts with clear explanations and develop testable hypotheses linked to scientific theory
- Moderate achievement: You show good understanding with clear descriptions and some hypothesis development
- Low achievement: You display limited understanding with basic outlines and follow given hypotheses
Investigative skills (design and method)
This evaluates the quality of your experimental approach and data collection.
- High achievement: Your design is clear and thorough with accurate data collection and analysis
- Moderate achievement: You show generally good design and methods with reasonable quality data
- Low achievement: Your design is unclear with limited or poor quality data
Investigative skills (analysis and conclusions)
This examines how well you interpret your results and draw meaningful conclusions.
- High achievement: You draw valid conclusions linked to your hypothesis and evaluate errors in your design
- Moderate achievement: You reach reasonable conclusions with some recognition of potential errors
- Low achievement: Your conclusions are limited with no recognition of experimental errors
Relating work to scientists and society
This assesses your ability to connect your investigation to the broader world of science and society.
- High achievement: You provide thoughtful reflexion on the wider importance of your findings
- Moderate achievement: You make some connections between your work and science/society
- Low achievement: You make very limited links to the broader context
Each assessment area contributes equally to your final grade, so it's important to give attention to all four components rather than focusing on just one area.
Important assessment information
The Biology in Practice Investigation is assessed by the State Examinations Commission (SEC), ensuring standardised evaluation across all schools. This investigation serves multiple important purposes:
- It allows you to connect theoretical biology with real-world applications
- It helps you develop practical skills that professional scientists use regularly
- It gives you experience in conducting independent research and presenting findings
- Schools have flexibility in organising the investigation to best support student learning
The investigation provides an excellent opportunity to demonstrate your scientific thinking and practical abilities while exploring biology topics that interest you. Take advantage of this chance to showcase your understanding beyond traditional exam formats.
Key Points to Remember:
- The Biology in Practice Investigation counts for 40% of your LC Biology grade - it's a major component worth serious attention
- You'll work in three phases: background research, experimental work, and final report writing
- Four assessment areas determine your grade: knowledge/understanding, investigative skills (design and analysis), and relating work to society
- This is your chance to be a real scientist - embrace the opportunity to conduct independent research
- The SEC provides the brief annually, so stay updated with current requirements and deadlines
