Class 12 2023-24 Engineering Science syllabus ISC: CISCE is one of the educational boards that ensure the delivery of required education to the growing future minds. It nurtures students to make them blossom so that they can spread the scent of knowledge and positivity to the world around them. In this whole process, academics play a major role. Can you imagine studies without knowing what is to be covered? No! Right? When you don’t know what you need to do then it becomes difficult to prepare for a task to meet the highest standards. Lina Nilson once said “The syllabus is not a contract, but a compass. It sets the direction for the course and guides students through the content.” We believe you will agree to this.
To help you with your Engineering Science syllabus we have framed this article to give an elaboration on the ISC Class 12 Engineering Science syllabus 2023-24. As per the ISC guidelines, if you have opted for physics then your eligibility to opt for Engineering Science is compromised. To know more, continue reading the syllabus highlights.
ISC Engineering Science Syllabus Highlights
- This subject may not be taken with Physics.
- The syllabus is designed for candidates who have followed a course with a bias towards engineering.
- The examiners will attach importance to an understanding of scientific principles and will look for evidence that these have been studied practically. The examiners may ask to see the practical notebooks.

List of suggested assignments for Project Work:
- Show mathematically that the energy of a simple pendulum is conserved. Also draw and interpret the following for the same:
- displacement-time graph
- kinetic energy-displacement graph
- potential energy-displacement graph
- total (mechanical) energy and displacement graph.
- Study and represent graphically the work done on a body of mass m under the action of a constant force and by a varying force. Show calculations and discuss.
- Study the fundamental forces in nature governing the diverse phenomena of the macroscopic and microscopic world. Discuss the progress related to the unification of these forces.
- You have studied about the strength of materials. In this context, discuss the following:
- Stress and strain, their types, Hooke’s law, Young’s modulus, elastic limit, permanent set and ultimate strength.
- Take a stress-strain curve for a metal and mark the relevant points on the graph.
- Is it correct that a material that stretches more is more elastic? Discuss with examples.
- Observe any five surfaces at home:
- Which surface produces more friction and which produces less friction (on the basis of type of material, surface finish, dryness/wetness). Discuss giving reasons.
- Frictional force opposes the relative motion (impending or actual) between two surfaces in contact. Discuss. Also, show graphically the relation between the force applied F and force of static friction fs, / force of kinetic friction fk for any pair of surfaces in contact.
