Class 10 CBSE Science Syllabus for Practicals

As internal assessment consists of a total of 20 marks so, students should not ignore the importance of practicals. Along with the theory CBSE Syllabus for Class 10 Science, they should also focus on practicals as well. This will help them score high marks and understand the theoretical concepts by practically performing the experiments. So, here we have provided the CBSE Class 10 Science Practical syllabus for students. They can also download the CBSE Class 10 Science Practicals.

List of Unit-wise Class 10 Science Experiments

The experiment list provides an idea of new Science projects a list of experiments and activities. So, students must go through this Practical CBSE Syllabus for Class 10 Science.
