How to Be Confident in Biology at High School Level Part 2 – a Complete Solution

by Aug 22, 2016Biology

Biology tends to be a very popular subject for high school students. While challenging in some respects, it may be considered the most interesting of the sciences. However interest and confident proficiency are different things. At high school level students often take more of an interest in Biology but not everyone manages to ace the subject. Many students feel intimidated by the complicated new scientific terms and processes they are introduced to.
To help with all of that, here is a basic structure of a standard high school Biology syllabus along with some specific tips on how to cover each of these topics that should tell you exactly How to be confident in high school level Biology:

  1. Cell Theory:


  • Every Biology syllabus at high school level begins with an introduction to the concept of cell theory.
  • The topics covered under this subheading are unicellular and multicellular organisms, cell structure and cell division.
  • Cell Biology always involves the extensive use of diagrams and microscopes. Use your resources well.
  • Practice your diagrams thoroughly. They function as mind maps, so ensure that they are neat and accurate. Label your diagrams diligently.
  • This topic includes the study of slides under a microscope. Ensure you maintain neat lab files for your practical work which will contribute to your final grade.

This makes an excellent project topic as cell models are easy to make and microscopic slides make for interesting presentations.

  1. Molecular Biology:

This is probably the most challenging part of the syllabus as students have trouble understanding the chemistry taught under this subtopic.
This includes the study of molecules, anabolism, catabolism, carbon compounds, water, production of carbohydrates, proteins, enzymes, structure of DNA and RNA, cell respiration and photosynthesis.
There isn’t very much to understand under this subtopic barring the two major processes of photosynthesis and cell respiration. Both processes are key concepts that need to be understood clearly with the help of diagrams. Everything else can be read and slowly assimilated in the memory.

  1. Genetics:
  • This is one of the most popular subtopics in the syllabus.
  • It includes the study of genes, chromosomes, meiosis, Mendelian inheritance and genetic modification.
  • This section is especially popular as it can include some engaging field work and case studies within its scope.
  • This section is best tackled with the help of neat tables and case studies involving mutations or genetic abnormalities.
  1. Ecology:
  • Includes the study of ecosystems, communities, energy flow, carbon cycling and climate change.
  • These are important topics that address key environmental issues of the day.
  • This subject provides great scope for dynamic projects including extensive field work.
  • These topics are also covered under Environmental Science.

Ensure you understand the key concepts of energy flow and carbon cycling. Make use of tools like energy pyramids, diagrams and flow charts to understand these subtopics.

  1. Evolution and Biodiversity:


  • This topic studies the evolution of species, natural selection and the classification of biodiversity.
  • Museums are a great resource when covering this topic.

It is essential to obtain a clear understanding of the process of natural selection and to obtain a rudimentary understanding of the logic behind the scientific names of various species. Though the names are Latin and unfamiliar, they are easy to remember once you understand the process of how species are classified first by genus and then species.

  1. Human Physiology:

Students thoroughly enjoy this subtopic and they relate to it when they understand the systems and processes of their own bodies.
This subtopic includes a study of the various systems working within the human body. For example- Digestive system, circulatory system, nervous system, immune system, endocrine system, respiratory system, locomotor system, renal system, cardiovascular system and reproductive system.
This topic must be studied with the help of clear diagrams and models. Practice your diagrams repeatedly as they help you remember key points.

  1. Plant Biology:
  • Studies plan systems and processes like transportation of water and food through xylem, phloem; growth and reproduction.
  • Ensure you have accurately labelled diagrams and a solid understanding of important concepts like osmosis.

Physical experiments to study xylem and phloem help make concepts clear and encourage habits of observation, experimentation and research. They also serve as excellent science projects when documented painstakingly.
Some important guidelines to help you make the most of your Biology preparation:

  • Take clear notes in class. Study your notes regularly to revise what has been covered in class.
  • Note down doubts and queries so that you may ask the teacher at the end of the lesson.
  • Read the text before class so that you are familiar with the material.
  • Practice answering the questions included at the end of each chapter in your textbooks.
  • Understand and memorize the scientific terminology.
  • Make mind maps and flash cards.
  • Conduct extensive lab research.
  • Use diagrams to understand complex concepts and illustrate your answers.
  • Practice drawing and labelling your diagrams.
  • Go over old question papers to get an idea of the kind of questions you can expect for your examinations.
  • Prepare answers to sample questions.
  • Keep track of your Biology assignments with the help of a clear schedule.
  • Ensure you make full use of your workspace by putting up charts and diagrams at eye level.

Biology is one of the most interesting subjects of study. High school Biology is only the tip of the ice berg in terms of all that this field has to offer. However it is an important beginning.  This structure gives you a clear approach to the basics of high school biology following which you should have no trouble tackling this subject confidently.
