You should first have a clear understanding of the Class 9 Chemistry syllabus under CBSE and what it basically entails. The Class 9 CBSE Chemistry syllabus is not that hard to grasp, provided you possess thorough knowledge regarding the examination pattern and the important chapters contained within the same. The CBSE Chemistry Class 9 syllabus contains the following:
- Unit I- Matter- Nature & Behavior
- Matter in our surroundings- Definition of what is matter, liquid, solid and gas, their characteristics, change of state-melting, i.e. absorption of heat, evaporation, i.e. cooling by evaporation, sublimation, condensation, freezing, density, volume and shape among other vital aspects.
- Is matter around us pure- This will include compounds, elements and mixtures along with homogenous and heterogeneous mixtures, suspensions and colloids along with basic units, molecules and atoms, particle nature and the law of constant proportions.
- Atomic and molecular masses and the Mole concept- This covers the relationship of the mole to numbers and the mass of particles.
- Structure of Atoms- This covers protons, electrons, neutrons, chemical formula of common compounds, valency and also Isotopes and Isobars among other vital aspects.
Examination Pattern for CBSE Class 9 Science
- The science paper will have 27 questions in all with 1 mark each while there will be 10 questions of 3 marks each, 3 questions of 2 marks each and 6 questions of 5 marks each.
- Internal choice will be available for 3 questions of 3 marks each, 2 questions of 5 marks each and one question of 2 marks.
- 12 marks will be there from practical based questions.
- 1 mark question will have to be answered with a sentence.
- 2 mark question will have to be answered in approximately 30 words.
- 3 mark question will have to be answered in approximately 50 words.
- 5 mark question will have to be answered in approximately 70 words.
- The theory examination in the Science paper will have 80 marks in total and candidates will get 3 hours for attempting this paper.
- Candidates should pay special attention towards labeling and diagrams alike.
Tips for Chemistry Examination
The CBSE Chemistry Class 9 examination can be successfully cracked if you follow these tips:
- Focus more on application-based questions from the chapter titled Matter in our Surroundings.
- Solve multiple numerical problems on the Mole Concept while studying the valencies of multiple elements.
- Practice writing down chemical formulae.
- Remember the important theories linked to multiple models of atoms.
Major examination tips for practical questions
- There will be two questions coming from the Chemistry portion.
- The Chemistry portion will contain questions which are numerical based and cover mixtures and compounds along with molecular mass as well.
General examination preparation tips for you to follow
- If you are studying Science on specific days of the week, sub-divide the same into Physics, Chemistry and Biology.
- Always start with the easier chapters and finish them in advance before taking up the difficult ones.
- You should study all important formulae and concepts carefully while writing them down once you finish the chapter as well.
- If you are tiring of concepts and regular notes, simply make charts, tables and diagrams for revision purposes.
- Eat properly while getting enough sleep and some recreation as well prior to your examination.
- Do not remain awake till the wee hours before your examination day.
- Do not divert yourself into anything else while you read the examination paper.
- Complete reading of the question is a must.
- Continue with any one pen throughout the examination without changing the ink.
- Answer only those questions which are you can comfortably cover first.
- Follow steps/bullets while answering questions.
- Answers which are neatly written with good handwriting always help.
- Answers should be to the point with a proper introduction and conclusion.
- Divide answers properly for 5 mark questions.
- Maintain time while not spending too much time on a single question.
- Revise your answers in the last 10-15 minutes as much as possible.
- Use a pencil to draw diagrams without using a pen for this purpose.
