About Science

Science is a free set of plain-language explanations of school science for classes 3 to 10. Each topic has a clear explanation, the key terms, a small activity to try at home, and quick questions with answers.

Where the content comes from

• Every explanation, activity, question and diagram is our own original work. Nothing is copied from textbooks, guide books or other websites.
• The science itself is standard school science, as taught in Indian schools and found in NCERT textbooks. Values such as the boiling point of water, the value of g, the speed of sound and the composition of air are the usual textbook values.
• The class named on a topic ("Classes 6 to 8") is a typical guide, not the syllabus of any board. Boards and schools place topics in different classes and change their syllabus from time to time. For examinations, follow your prescribed textbook.

Safety

The activities use everyday things and are chosen to be safe. Children should take an adult's help with anything hot or sharp, and must never experiment with mains electricity or unknown chemicals.
