SOF Science Practice Worksheets

Topic-wise practice worksheets following the pattern of the SOF National Science Olympiad, from Class 1 to Class 10. Topics run from plants, animals and the human body at the younger classes through matter, force, light and electricity to the more demanding chemistry and biology of the upper classes. The olympiad's science questions reward applied understanding rather than recall — a child who has memorised that water evaporates may still be caught by a question about washing drying faster on a windy day. The worksheets here are written in that spirit, with every question carrying a full worked solution explaining the reasoning rather than just naming the right option. Sample questions with solutions appear on each worksheet's page, so you can see the difficulty before printing anything.
