Ground Water Ground Water click here for the adobe version recommend this activity to a friend I like this activity because it gives the children a chance to see how the earth works and why it is important to consider what we pour onto the ground. Most children who grow up in the city take their water supply for granted. Everything that is placed on the ground can find its way into our water.
Some soils are more absorbent.
The children should be able to tell time or sense the length to time passing. They should also be able to understand concepts like absorbing, run off and water tables. Plenty of towels. Ask for three volunteers. Hand each volunteer one 2-liter bottle.
