Do not leave your IA until the last minute. The iterative nature of planning, experimenting, and refining takes time.
Detailed Explanation
Starting your Internal Assessment early is crucial because it involves multiple stages of planning, conducting experiments, and refining your work. This is not a simple task that can be completed in one go. Instead, it's an ongoing process where feedback and new findings may lead you to adjust your methods or findings. By giving yourself ample time, you can thoughtfully ponder each step and produce a deeper, more insightful report.
Examples & Analogies
Think of a chef preparing a complex dish. If they wait until the last minute, they might rush through cooking, which can lead to mistakes. However, if they give themselves enough time, they can taste, adjust flavors, and present a wonderful meal. Similarly, your early start on the IA allows for proper experimentation and tweaking.
Keep a Detailed Lab Notebook

Record everything β raw data, observations, thoughts, unexpected events, dates, times. This is your primary record and invaluable for writing the report.
Detailed Explanation
A detailed lab notebook serves as a comprehensive record of your investigation. This includes all your raw data, observations during experiments, your thoughts about the process, and any unexpected occurrences that arise. By maintaining a well-organized notebook, you will have all your information readily available when you write your report. This makes your findings reliable and supports your conclusions with firsthand data.
Examples & Analogies
Imagine trying to recall details from a memorable trip without taking notes. You might forget the names of places you visited or important moments that happened. Your lab notebook works similarly; it captures every necessary detail of your investigation so you can reference it when you write your report.
Perform Preliminary Experiments

Conduct small-scale trials to test your methodology, identify potential problems, and optimize conditions before doing your main runs. This helps refine your procedure and variable ranges.
Detailed Explanation
Preliminary experiments are vital for testing your proposed methodology on a smaller scale. They allow you to identify any issues that might arise before you commit to your full experiment. By optimizing your conditions in these preliminary trials, you can refine your procedure to minimize errors and make it more effective. This step ensures that when you conduct your main experiment, your results will be more reliable.
Examples & Analogies
Consider a scientist trying to launch a rocket. Before launching the full model, they conduct smaller test launches to check if everything works correctly. This allows them to make necessary adjustments and avoid major failures during the primary launch.
