Syllabus for Class 10 Science
NCERT Class 10 Science Syllabus is the stepping stone to exam preparation. It provides a brief introduction of the units, chapters covered and time allocated for each unit. Science being a vast subject requires a proper strategic plan for study. So, it is crucial that as the session begins students must go through the syllabus. Here we have provided the latest NCERT Class 10 Science Syllabus for 2019-20 academic year.
Most of the questions in class 10 science exam are asked from the syllabus itself. So, while studying students must be stick to the syllabus and refer it every time. The NCERT Class 10 Science Book is designed in accordance with the syllabus and is recommended to CBSE students. We have provided the NCERT Class 10 Science Syllabus in PDF for free downloading.

CBSE Practical Syllabus for Class 10 Science
As internal assessment consist of 20 marks so students must not ignore the importance of practicals. Along with the theory they should also focus on practicals. This will not only help them in scoring high marks but also understanding the theory concepts through practicals and experiments. So, here we have provided the CBSE Class 10 Science Practical syllabus. Go through it and experiment list. Students can also download the. It provides the idea on new science projects, list of experiments and activities.
List of Class 10 Science Experiments
1. Studying the properties of acids and bases (HCl & NaOH) on the basis of their reaction with:
- Litmus solution (Blue/Red)
- Zinc metal
- Solid sodium carbonate
2. Performing and observing the following reactions and classifying them into:
A. Combination reaction
B. Decomposition reaction
C. Displacement reaction
D. Double displacement reaction
i) Action of water on quicklime
