Activity 11.4: Let us investigate

• Collect samples of soil from different areas around your home and school.  
• Guess what could be there in different soils. 
• Observe carefully each soil sample and note its colour. 
• Touch each soil sample and feel its texture. 
• Observe the soil samples with your naked eye. If you have a magnifying lens, look at the soil through it. 
• Record your observations in Table.
• Is there any difference between your guess and what you can actually observe when you look closely? 
• Do you see any differences in the soil samples taken from different places? 
• Do you see differences in what you are able to observe with your naked eye and what you can observe with a magnifying lens?

Ans: (This is a Sample answer; students are advised to do the activity on their own) Yes, there were differences between my guesses and the actual observations. For example, the farm soil looked more fertile than I thought, and the garden soil had many tiny insects that I could only see with a magnifying lens. The soil samples from different places were not the same in colour and texture. With the naked eye, I could see only colour and roughness, but with the magnifying lens, I noticed fine particles, small stones, roots, and even insects.

Activity 11.5: Let us conduct a survey
