1. Take soil samples.
2. Take a plastic funnel and place a filter paper in it as shown in figure.
3. Weigh 50 gm of dry soil and pour it into the funnel.
4. Take 100 ml of water in a measuring cylinder.
5. Then pour the water on the soil drop by drop.
6. Do not let all the waterfall at one spot.
7. Pour water all over the surface of the soil until it starts dripping out of the funnel.
8. Observe how fast water passes down the soil.
9. Measure the amount of water collected in the beaker.
10. Calculate the difference between amounts of water.
11. By taking different soils in the funnel and calculating the difference between amount of water we can determine the percolation rate of different soils.
