May 2023 5월 시험에 사용된 IA입니다. 최종적으로 22/24로 7점을 받았습니다. 특히 Biology IA에서 가장 중요한 그래프 분석과 strength/weakness작성하는 부분이 강점이라고 할 수 있습니다.
따라서 아직 분석에 자신이 없는 학생들에게 강력히 추천하며 만점 가까이 받고자 하는 학생에게 큰 도움이 될 것입니다.

 

[본문내용]

1. Introduction

1.1: Research Question
To what extent does different concentrations of hydrogen peroxide (0, 1, 2, 3, 4, 5%) affect the growth rate (measuring radicle length by 4 days) of Phaseolus vulgaris.

1.2: Personal Engagement
As the world continues to industrialise, abiotic sources of stress brought on by urbanisation have led to the contamination of natural resources like soil and water by contaminants, such as pesticides, heavy metals, and household chemical wastes. Those negatively affect not only the environment’s quality, but also entire ecosystems in general. Soil is a valuable non-renewable resource that is essential for plant growth and is the foundation of the majority of ecosystems in the world. However, as humans cultivate crops and plants, numerous consequences are aroused, such as reduction of nutrients in plants (Soil Pollution and health). As a leader of the Gardening CAS project, we foster school gardens to provide organic fruits and vegetables. However, unfortunately, all the plants died due to lack of nutrients in the soil. Our group tried to buy new soil, but it was too expensive, and the school could not offer all the money that we needed to buy new soil. Fortunately, I got some ideas from topic 9 IB biology, which is the plant biology unit. By learning the structure and growth of plants, I have realised that some chemicals can supply nutrients to plants, which leads to faster growth of those…
