Objectives:
 |
To
observe the ability of a stream to erode, transport, and deposit
materials.
|
|
To
observe the effect of a stream on land supporting structures.
|
|
To locate and
identify several erosional and depositional landforms. |
Materials:
Under-the-bed box
Duct Tape

two-thirds.
-
Begin
pouring water, slowly and steadily from a watering can that is held
slightly above the high end of the stream table.
-
Observe
the small stream that is forming, and it’s transportation of the
sand.
-
Smooth
the sand and use your finger to create a winding, meandering channel.
Pour a steady trickle of water down this channel.
