Let's prove soil contains water!!


Garden soil

Coffee can

A sheet of plastic or glass

Black construction paper


A sunny window


Fill the can about one-half full of garden soil.

Tape the black construction paper around the coffee can, so that the coffee can's outer surface is covered with black construction paper.

Now place the plastic sheet or glass on the top (opening) of the can.

Put the can near the sunny window for a few days (7-10 days)

Observe: Water droplets began to form on the underside of the plastic sheet or glass.

You can prove the water is from the soil not by the air in the can by repeating the experiment but this time without the use of soil. In this experiment the water will be very less compared to the experiment with the soil, or there would be no water!!!!
