explain an activity to show that soil contain moisture

 take a tube which can be boiled put some soil samples in it.heat the test tube on a flame. after sometime you can see the drops on the surface on tube which shows that soil contains moisture.this happens because after heating the water or moisture in the soil evaporates and moves up and get condensed on the cooler inner walls of the upper surface of the boiling tube.

1)Put some soil in a testube.

2)Heat the testube so that the water in the soil gets boiled and evaporates

3)The evaporated water condenses and forms water droplets when it reaches the top of the testube,as it comes in contact with the cool inner surface of the testube.

4)The water droplets indicate that soil contains moisture

Hope this helps :)

Thumbs up Please :)
