Air Water and Weather (Class 1)

What this worksheet covers

This is a fifteen-question practice worksheet on air, water and weather for Class 1, written to the pattern of the SOF National Science Olympiad (NSO). It carries 18 marks and is designed to be attempted in 30 minutes, split across three sections — Air and Water, Weather and Seasons and Achievers Section. Every question is multiple choice with exactly one correct option, and every one comes with a fully worked solution rather than just an answer key — so a child who gets one wrong can see where the reasoning went astray instead of only learning that it did.

   • BBecause the glass is too small
