NIOS Class 10 Home Science Activity 2.5 Solutions- Food and Nutrients

NIOS Class 10 Hom Science Activity 2.5 Solutions is part of Chapter 2, Food and Nutrients. This activity helps students understand the importance of water in our daily diet.

In the Food and Nutrients chapter, water is explained as an essential component for digestion, removal of waste and maintaining body temperature. This post provides a complete, simple and exam-oriented solution to activity 2.5.

Chapter Name: Food and Nutrients

Activity Number:2.5

Activity 2.5 – Observation of Urine Colour and Water Intake

Aim

To understand the importance of water in our body by observing the colour of urine when water intake is low and when water is taken regularly.

Material Required

    1. Drinking water

    2. Glass or bottle

    3. Pen and notebook

Procedure

 First, we observe the colour of urine after not drinking water for about 6-8 hours, especially during the first urine passed in the morning.

After this, we consumed water regularly at intervals of every half an hour. Then we again observed and recorded the colour of urine. Finally, we carefully note both observations in the given table.

Observation

 

Interval between water intake	Colour of urine
Water after 6-8 hours	Dark yellow
When water is taken every ½ hour	Pale yellow/almost colourless

 

Explanation

When we do not drink water for a long time, the body becomes dehydrated, and urine becomes dark yellow because waste materials are more concentrated. When we drink water regularly, these waste products get diluted and are easily removed from the body.

 As a result, the urine becomes lightly yellow or almost colourless. This clearly shows that adequate water intake is essential for proper body functioning.

Conclusion

This activity proves that drinking sufficient water is very important for maintaining good health. Regular intake of water keeps the body hydrated, helps digestion, circulation of nutrients, temperature regulation and removal of waste products from the body.
