SAS – Serious About Science



Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Importance of Science

Science has invaded every branch of modern life. It is the noise of machines, cars, mills and factories, etc. which awakens us every-day in the morning. The food we eat, the clothes we wear, the books and papers we read, the recreations we enjoy, the games we play – all have something or other to do with the application of science.

Every person feels the effects of science in every sphere of life. It is not merely the electric light or the electric fan, the radio or the cinema that displays the power of science in our daily life, but everything we do or is done to us is in some way or another connected with science.

Science is a way of life. Science is a perspective. Science is the process that takes us from confusion to understanding in a manner that's precise, predictive and reliable - a transformation, for those lucky enough to experience it, that is empowering and emotional.

Importance Of Learning Science In School

  • Develops problem-solving skills

With the knowledge of science, you learn to think logically and solve a problem. It is this problem-solving skill, which is learnt in the early years that have enables a person to solve problems.

  • Awareness about technology
Learning the basics of how certain devices work can help you develop ideas of your own and invent new technology.

  • How to conserve natural resources
All aspects of the environment have a deep impact on our lives. As a student, science helps you to learn about how the earth functions, and how to make use of natural resources.

  • Instills survival skills
Science helps you learn about the various weather conditions, and helps you distinguish between normal weather and dangerous weather.


Go through every topic. Also revise the high order thinking skills (HOTS) questions thoroughly. Those who wish to score 100 out of 100 should attempt all NCERT questions and additional exercises as many times as possible. Practice numericals and solve at least five previous years' papers. Every paper should be solved in the given three hours.

Read the CBSE sample papers thoroughly. Answer questions in the form of points. Underline the key words. Draw big diagrams where needed and label them. Attempt all questions of one section together.

Have enough practice of numerical-based chapters and do not leave out lessons on solids, solutions. revise each and everything.

some additional tips :

  1. go for making short notes or summary of the chapters.
  2. Notes should contain each and every important concept, definitions, shorts answers and everything important that is there in your textbooks, coaching, reference books etc.
  3. Go systematic. prepare your schedule properly.
  4. Keep in touch with your teachers they will help you a lot.


Fleming Left Hand Rule

Whenever, a current carrying conductor comes under a magnetic field, there will be force acting on the conductor and on the other hand, if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor. In both of the phenomenons, there is a relation between magnetic field, current and force. This relation is directionally determined by Fleming Left Hand rule and Fleming Right Hand rule respectively. 'Directionally' means these rules do not show the magnitude but show the direction of any of the three parameters (magnetic field, current, force) if the direction of other two are known. Fleming Left Hand rule is mainly applicable for electric motor and Fleming Right Hand rule is mainly applicable for electric generator. In late 19


century, John Ambrose Fleming introduced both these rules and as per his name, the rules are well known as Fleming left and right hand rule.
Hans Christian Ørsted often rendered Oersted in English; 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. He is still known today for Oersted's Law. He shaped post-Kantian philosophyand advances in science throughout the late 19th century. The oersted (Oe), the cgs unit of magnetic H-field strength, is named after him.

Tips for improving performance in science exam

  1. Switch it up.

    Don’t stick to one topic; instead, study a bunch of different material in one sitting. This technique helps prepare us to use the right strategy for finding the solution to a problem.

  2. Put yourself to the test.

    Quizzing ourselves may be one of the best ways to prepare for the real deal.

  3. Write it out.

    Put those third-grade penmanship lessons to good use.

  4. Come together (right now).

    Group work doesn’t fly with everyone, but for those who benefit from a little team effort, a study group’s the way to go.

  5. Learn what works.

    Some people are early birds, some are night owls; some prefer to study with a pal, others need complete and total silence. Experiment to find what’s most effective for you, and then stick with it!

  6. Tell a tale.

    Turning the details you need to remember into a crazy story helps make the information more meaningful.

Strategy for quick revision of science after completation of syllabus

  1. Making a Revision Plan

    As always, planning is key.

    • Create a Revision Timetable
      You should start revising at least five or six weeks before your exams are due to start. Do be realistic about the goals you set in the time you have available, and remember you need to allow breaks now and then.
    • Balance your subjects
      Allocate topics to days, and make sure you have enough time for everything you want to revise. Balance the time you have available between your various courses. Do not neglect courses you find particularly easy or difficult.
    • Identify key topics
      For each course, identify which topics to revise. At the very least, you should cover twice as many topics as the number of questions you need to answer
    • How to Revise

      There are three key revision methods:

      1. note-taking/note-making
      2. memorising
      3. drafting model answers
      4. Memorising

        There is no way around this task - to do well in exams, you have to remember your material. Ultimately, you have to work out the way of doing this that works best for you. Some of these approaches may help:

        • Look at your notes for a topic on three or four occasions. This will fix them in your mind better than a once and for all approach.
        • Predict a page of notes in your mind before you look at it. What you have forgotten will bring itself to your attention as you read.
      5. Revision all year round

        Revision should not be a last-minute attempt to make up for poor study habits in the previous eight months. As one topic quickly succeeds another in each course, it's easy to forget previous work all too soon.

        • your lists of readings and references. Collect lists of past questions and past papers.
        • Note down what you have not yet had time to do, and the key issues you have not yet investigated.
        • Don't let work pile up. Even if you make the time to catch up, it may be impossible to get hold of readings for topics a few weeks before the exam.
        • Try to read through your notes periodically. Use them to form an overview of the course so far. Make connections between what you have studied and what is to come.
