IA for Bio HL Topic: Testing the Impact of Temperature on the rate of Ultra-High-Temperature Milk Spoilage Overall Score of 7

IB Biology SL IA: Investigating the effect of different temperature intervals on the pH of milk (UHT Milk) and rate of spoilage. I got a high 6 in Biology SL (just a few points off a 7), and this IA played a major component in my grades.

This is my IB Biology SL Internal Assessment. I hope this exemplar can help you better structure & format your IA & guide your analysis. Best of luck :) I scored a 7 in IB Biology SL & 44/45 overall in my Diploma

When the baffling “The Dress'' Meme first blew up it created a divide among internet users all around the world. Some argued that the color of the dress was ‘Black & Blue’ and the rest saw the colors ‘White & Gold’.

And more research into this topic made me aware that the way humans perceive colors also depend on sex – that there are certain psychological and physiological...

This is my IB Biology SL IA on the effect of pectinase immobilisation on pectin hydrolysis. This IA received an A* and I got a 7 for the subject. It provides a clear framework for introduction, methodology, analysis and evaluation. I hope you find it helpful!

This is my IB Biology SL Internal Assessment which aims to investigate the question: "How does the heart rate of teenagers aged 17-19 change after using the leg press machine in the gym at two load intensities, including 65 per cent (15 repetitions) and 90 per cent (4 repetitions) of their one-repetition maximum (1RM)?" It was externally graded by IB Examiners in the May 2021 session and scored a level 5 (15/24). Written by an IB Student who scored a 6 in IB Biology SL and a total of 41/45 IB p...

IB Biology Internal Assessment Higher Level (HL) on the effect of low-power microwave radiation on seed germination, which received a score of 22/24 in the IB moderation, written by a student who received a 7 for the subject of Biology HL, and an overall score of 44/45 for the IB Diploma.

This document includes my entire biology IA which scored an overall 7. It focuses on topic 2.5, being enzymes in the IB syllabus, where it examines how increasing the concentration of an alpha-amylase inhibitor (Phaseolus Vulgaris) affected the rate of hydrolysis of starch into maltose. This hydrolysis is measured through a colorimeter and iodine test.
