A teacher is trying to introduce her class VII students to different kinds of soil. She begins by introducing the names of three kinds of soil i.e. sandy soils, clayey soil and loamy soil. She explains the properties of each soil in term of its particulate nature. She then demonstrates one sample of each kind of soil and shows the students the difference in percolation rate of an examples. How would you evaluate this approach from an inquiry oriented perspective?
Consider the following statements and choose the correct answer:
1. Average density of soil is 2.65 gms. per ml.
2. The spaces present between soil particles in a given volume of soil are called pore spaces
3. Porosity of the soil decreases with the increase in the percentage of organic matter in the soil
