The syllabus of Science in Class 7 continues upon the base that was created with the Science syllabus of Class 6. Topics related to fibres, changes in substances, electrical current, and water are dealt with by creating a link between them and it’s introductory counterparts studied in previous classes. New concepts of nutrition, acidic and basic substances, heat, weather, reproduction, light, and motion are also introduced.
- The NCERT textbook – Study your NCERT textbook for class 7 science as thoroughly as possible and practice all the questions given in the book to ensure you have a solid grip of the entire syllabus. Once you are absolutely clear with all that, you can move on and practice with other reference books or additional material. You can also refer to Vedantu NCERT solutions for class 7 science. The following chapters have been included in the NCERT textbook for science in class 7.

- Practice profusely – You must practice your answers by writing. Oral and reading practice does not help much in the case of science subjects because you have to internalize concepts. The class 7 science exam will not have a vast diversity of questions. Hence, you can comfortably score well with significant practice and thorough learning.
- Understand your Concepts – A common problem among young learners is to mug up answers and memorize formulas instead of trying to understand them. Do not make this mistake. Make it a point to try and understand your concepts so that you have all answers already learnt. This way, if you have to solve a question on the derivation of formulae, you will be able to tackle it easily because you comprehend the logic behind the derivation. You can even try watching videos on the concepts that you are learning so that you can easily understand them through practical application and detailed explanations. Videos will also allow you to develop a genuine interest in the subject with edutainment.
- Delve Deeper – Always try to comprehend concepts with as much depth as possible, and then you can begin solving a variety of questions and numerical problems from different sources. Rather than taking the test of the entire syllabus at once, it is a better idea to attempt tests based on one chapter or one topic first. This will clarify your topics singularly as well as build your confidence. You will also be able to point out your doubts better through this process. Practice writing answers with the help of solving sample papers, question banks, and previous year’s question papers. You can even try to get a solution to real-world problems with your knowledge.
- Weightage and marking scheme – Always try to give more importance to the topics that carry greater weightage in the exam. Solve the previous year’s question papers to gain confidence and also to get an exam-like feel. At the same time, this practice will help you brush up the whole syllabus just before your exam for even better results.
- No Mugging Up – It is of no use to simply read or mug up the topics. It is mandatory to practice them well. This is probably the most fundamental concept of science that you cannot ‘read’ and expect to score well just by reading the answers. Instead of that, chalk out a proper timetable that will enable you to devote significant time to practising the concepts, questions, and numerical problems.
