was the cave made?
- Did someone dig in and carve the opening in the cave?
- Is it the result of a volcano eruption?
- Did weather wear the opening in the cave?
II. Let's Make a model of a cave.
A. List of items needed:
12. baseball ball or tennis ball
- Food color
III. Preparing the Layers of land Used In Making the
- A. Take 2 cups of flour, any kind, 2 cups of
salt and 1
cup water any temperature mix these ingredients together for
a play dough consistence
- B Mold dough in a rectangular, square or round
You may use a container in any of the previously named shapes to put
in. Turn your container over and ease your dough out.
- C. Push your ball in from the bottom
about an inch of dough above the ball.
IV. Next you will place another layer of land on top of
your model of
- The order of layers is optional. For example, you
can place small pebbles across the top of your model
- Layer three can be sand. Put the sand above the
pebbles. You might mix some water with the sand to make a
- You can place a few herbs on the 4th layer
- Use the play dough or commercial clay for your 5th
V. Now its time to show how water is going to erode the layers
of the model
A. Remove the ball from the model. Pour
top. Students can take turns pouring this water on top of the
model until you see
crevices and cracks develop in your model.
- Each student pouring will
equate to 100 years of erosion. This is purely a guess.
- Homework is to figure out how
long it takes for water to erode land.
