Experiment Soil

Soil means different things to different people. For a farmer, soil is where he grows his crop, for a civil engineer it is on which he builds the roads. To a mason, soil is the main ingredient of bricks, while to a geologist soil means possibility of hidden minerals. As part of grade 7 science curriculum, this is how the topic of Soil began. The learners conducted experiments on different types of soil to calculate the rate of absorption of water and percolation of water and concluded how different types of soil are useful for different purposes.
