Our Body and Senses (Class 2)

What this worksheet covers

This is a fifteen-question practice worksheet on our body and sense organs for Class 2, written to the pattern of the SOF National Science Olympiad (NSO). It carries 18 marks and is designed to be attempted in 35 minutes, split across three sections — Parts of the Body, Senses and Health 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.

Sample questions from this worksheet

A preview of what's inside Our Body and Senses (Class 2) — the PDF has the full set, and every question comes with a worked solution like these.

1. 1. The bony frame that gives our body its shape is called the _______.

   • ASkeletoncorrect
   • BSkin
   • CMuscle
   • DBrain
   Solution: The skeleton is the frame of bones inside our body. It gives us shape, holds us upright and protects the soft parts inside.

2. 2. Which set of teeth do we use to tear food?

   • AIncisors
   • BMolars
   • CCaninescorrect
   • DMilk teeth
   Solution: Canines are the pointed teeth beside the front teeth, and they are used for tearing. Incisors cut and molars grind.

3. 3. Why can we bend our arm at the elbow but not in the middle of the upper arm?

   • ABecause the upper arm has no muscles
   • BBecause there is a joint at the elbow but not in the middle of the bonecorrect
   • CBecause the elbow is softer
   • DBecause the upper arm is too long
   Solution: Bones themselves are hard and cannot bend. We can only bend where two bones meet, so we bend at the elbow because there is a joint there but not in the middle of the bone.
