This means the investigation carries the same weight regardless of which level you are taking.<\/p>\n<p>To put this in perspective: The IB Physics IA is worth more than any single written exam paper. A well-executed investigation can meaningfully lift a student&#8217;s overall score, while a poorly structured one can drag down an otherwise strong exam performance.<\/p>\n<table>\n<tr>\n<th colspan=\"1\" rowspan=\"1\">Component<\/th>\n<th colspan=\"1\" rowspan=\"1\">Weighting<\/th>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">IB Physics IA (internal assessment)<\/td>\n<td colspan=\"1\" rowspan=\"1\">20%<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Written Examinations (Paper 1, 2, 3)<\/td>\n<td colspan=\"1\" rowspan=\"1\">80%<\/td>\n<\/tr>\n<\/table>\n<blockquote><p>One critical detail often overlooked is that the IA is graded out of 24 marks total, and these marks are then scaled to fit the 20% contribution.

Note that while many students and teachers informally reference &#8220;five criteria,&#8221; the official IB Physics IA assessment structure uses four main graded criteria, with personal engagement embedded within the Research Design criterion in the current framework. The categories below reflect the functional areas examiners evaluate.<\/p>\n<h3>Research Design (6 marks)<\/h3>\n<p>This criterion evaluates whether your investigation has a clear, focused, and scientifically valid structure. The examiner wants to see a precise research question, a logical method, and evidence that you understand your variables.<\/p>\n<p>A strong Research Question (RQ) follows this format: &#8220;How does [Independent Variable] affect [Dependent Variable] when [Controlled Variables] are held constant?&#8221; Vague questions such as &#8220;Does temperature affect resistance?&#8221; Will not score well. Specificity is what separates a high-scoring IA from an average one.<\/p>\n<h3>Data Analysis (6 marks)<\/h3>\n<p>The IB Physics IA assessment rewards students who handle data with precision and transparency. This section must include raw data tables, qualitative observations recorded during the experiment, and measurement uncertainty in IB Physics IA format, meaning every instrument&#8217;s resolution and uncertainty must appear in your column headers.<\/p>\n<p>You are also required to produce a processed data graph that includes error bars and both a best-fit line and a worst-acceptable-fit line. These are not optional decorative features; they are assessed components.<\/p>\n<h3>Conclusion (6 marks)<\/h3>\n<p>A common mistake we see at <a href=\"https:\/\/times.edu.vn\/\">Times Edu<\/a> is students writing a conclusion that simply restates their data without making a clear scientific argument. The Conclusion criterion specifically rewards students who link their findings back to the original research question and compare their experimental result against an accepted literature or theoretical value.<\/p>\n<p>You must calculate a percentage error using this formula:<\/p>\n<p><strong>Percentage Error = |( Experimental Value &#8211; Literature Value ) \/ Literature Value| x 100%<\/strong><\/p>\n<p>If your percentage error is high, you do not lose marks automatically; you gain marks by explaining why the discrepancy exists and what it tells you about your method.<\/p>\n<h3>Evaluation (6 marks)<\/h3>\n<p>This is where many students lose marks they cannot afford to lose. The Evaluation criterion asks you to identify specific errors, explain their impact on your data, and propose realistic improvements.<\/p>\n<p>Weak evaluations use vague language. High-scoring evaluations are precise and actionable. The table below illustrates the difference clearly.<\/p>\n<table>\n<tr>\n<th colspan=\"1\" rowspan=\"1\">Weak Evaluation<\/th>\n<th colspan=\"1\" rowspan=\"1\">High-Scoring Alternative<\/th>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">&#8220;Human error caused mistakes.&#8221;<\/td>\n<td colspan=\"1\" rowspan=\"1\">&#8220;Reaction time delay (&plusmn;0.2 s) created a random error that inflated measured drop times systematically.&#8221;<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">&#8220;The ruler wasn&#8217;t perfectly straight.&#8221;<\/td>\n<td colspan=\"1\" rowspan=\"1\">&#8220;A zero error on the wooden metre rule introduced a systematic error of +0.05 cm across all distance measurements.&#8221;<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">&#8220;We should use better equipment.&#8221;<\/td>\n<td colspan=\"1\" rowspan=\"1\">&#8220;Replace the manual stopwatch with a dual-gate laser photogate system to eliminate human reaction time entirely.&#8221;<\/td>\n<\/tr>\n<\/table>\n<h3>Personal engagement<\/h3>\n<p>Personal engagement in IB Physics IA refers to the authentic connection between you as an individual and the investigation you are conducting.

A precise RQ locks in your method from the very start.<\/p>\n<p><strong>Mistake 2: Missing or incorrect uncertainty propagation<\/strong><\/p>\n<p>Measurement uncertainty in IB Physics IA is not just about recording that a ruler has a &plusmn;0.05 cm uncertainty. You must show how that uncertainty flows through every calculation. Students who record raw uncertainties but ignore them in their processed data lose marks in both Data Analysis and Conclusion.<\/p>\n<p><strong>Mistake 3: A conclusion that describes rather than argues<\/strong><\/p>\n<p>The Conclusion criterion rewards scientific reasoning, not data description. Writing &#8220;my results show that as temperature increased, the refractive index decreased&#8221; is a description. Writing &#8220;this negative relationship is consistent with the theoretical prediction derived from the Cauchy equation, with a percentage error of 3.4%, which falls within the range explainable by thermal expansion uncertainty&#8221; is an argument.<\/p>\n<p><strong>Mistake 4: Generic evaluation statements<\/strong><\/p>\n<p>This is perhaps the most preventable source of mark loss. Examiners have read thousands of IAs where students write &#8220;human error was a limitation.&#8221; That phrase earns zero credit. Every limitation must be named specifically, quantified where possible, and matched with a specific, technically feasible improvement.<\/p>\n<p><strong>Mistake 5: Ignoring secondary data rules<\/strong><\/p>\n<p>Secondary data in IB Physics IA can be used, but only as a source of literature values for comparison in the Conclusion section. Your core data must be original and self-collected. A common mistake is using published datasets as the primary source of experimental results, which invalidates the Data Analysis and Research Design criteria entirely.<\/p>\n<p><strong>Mistake 6: Poor personal engagement<\/strong><\/p>\n<p>Students sometimes write their personal engagement as an afterthought, adding a single generic sentence to the introduction. Personal engagement in IB Physics IA should be woven through the report, appearing in the introduction as motivation, in the methodology as choices you made, and in the evaluation as reflection on what you would do differently.<\/p>\n<p><strong style=\"color:#f00;\">>>> Read more:<\/strong> <a class=\"xem-them-link\" href=\"https:\/\/times.edu.vn\/en\/ib\/ib-physics-common-mistakes\/\">IB Physics common mistakes<\/a> 2026: The errors that cost students the most marks<\/p>\n<h2>Frequently asked questions<\/h2>\n<p><strong>What is the IB Physics internal assessment and what should it contain?<\/strong><\/p>\n<p>The IB Physics internal assessment is an individual scientific investigation that forms 20% of your final grade. It should contain an introduction with personal engagement, a specific research question, a variables table, a labeled apparatus diagram, a reproducible methodology, raw data with uncertainties, processed data with graphs, a conclusion with literature comparison, and a structured evaluation.<\/p>\n<p><strong>How many pages should the IB Physics IA report be?<\/strong><\/p>\n<p>The recommended IB Physics IA page count is approximately 12 pages, corresponding to a word count of around 3,000 words. Pages that contain only diagrams, tables, or graphs do not count toward this limit. Exceeding this length significantly can actually harm your score, as examiners may stop reading after a certain point.<\/p>\n<p><strong>How much of the final IB Physics grade does the IA contribute?<\/strong><\/p>\n<p>The IA grade contribution in IB Physics is 20% of your total final mark for both SL and HL students. The remaining 80% comes from the written examinations.<\/p>\n<p><strong>What are the four criteria used to assess the IB Physics IA?<\/strong><\/p>\n<p>The four IA criteria in IB Physics are Research Design (6 marks), Data Analysis (6 marks), Conclusion (6 marks), and Evaluation (6 marks), for a total of 24 marks. Personal engagement is assessed as part of Research Design and is reflected throughout the report.<\/p>\n<p><strong>When during the IB Diploma course is the IB Physics IA submitted?<\/strong><\/p>\n<p>The IA is typically submitted during the second year of the IB Diploma Programme, though individual school timelines vary. Most students begin planning and collecting data in Year 1 and finalize their written report in the first half of Year 2. Check your school&#8217;s internal deadline, as missing it can result in an unassessed submission.<\/p>\n<p><strong>Can you use secondary data in an IB Physics IA?<\/strong><\/p>\n<p>Secondary data in IB Physics IA is permitted, but only as a reference point, not as your primary dataset. You may use published literature values to calculate percentage error in your Conclusion section. All data used in your Data Analysis section must be original and collected by you during your investigation.<\/p>\n<p><strong>How do you demonstrate personal engagement in the IB Physics IA?<\/strong><\/p>\n<p>Personal engagement in IB Physics IA is demonstrated through three key elements: A specific and authentic reason for choosing your topic in the introduction, evidence of independent thinking in your methodological choices, and reflective commentary in your evaluation about what the experience taught you as a scientist.
