1. Make a cone-shaped base for papier-mâché by sticking pieces of coat hanger in wood base

diagonally. Fill in under wires with wadded aluminum foil.

2. Cover cone with papier-mâché. Leave an opening in top where jar lid can be set. Let dry.

3. Paint with tempera or acrylic paint.

4. Set jar lid upside down in top of volcano.

California Inland Empire Council

Make Sandstone:

Materials:

Water, Salt, Nail, a small saucepan, spoon, fine sand (about one quart), a plastic or cardboard container, aluminum food container.

Pour one cup of water into a small saucepan and heat it on the stove over medium heat.  As the water heats, add the salt and mix well.  Continue adding salt and mixing it well until no more will dissolve in the water.  Remove the pan from the heat.  Place the sand in a deep, plastic container that is large enough for mixing.  Pour the salt solution into the sand and mix thoroughly.  The sand should be completely moistened.

Punch tiny holes into the bottom of an aluminum food container with a nail.  Press the sand and salt mixture into the container and pour away any excess water.  Keep this experiment in a warm, dry spot for several days.  After the sand has dried out, lift the chuck of material from the container and examine it.  You have just made sandstone.

The sandstone just made was created in much the same way that nature makes it. The salt clings to the particles of the sand and holds them together.  If you find sandstone in nature, you will find it is made of several layers.  This occurs when one sandy sediment is laid on top of another.  These layers are pressed together over time to make the rock you see today.

The Earth Bowl
California Inland Empire Council

The Earth Bowl is a three dimensional, edible representation of the earth in cross section.  (If time allows, have scouts participate in measuring the ingredients and constructing the Bowl.)

Materials:

4 oz. pkg. raspberry gelatin dessert

4 oz. pkg. instant vanilla pudding

8 oz. pkg. black cherry gelatin dessert

4 cups boiling water (can be boiled and kept hot in thermos)

4 cups cold water

3 mixing bowls

12 graham crackers

1/2 cup melted margarine

1/4 cup granulated sugar

10" diameter clear glass bowl

(Small paper cups and spoons for after discussion)

Procedure:

Make the gelatin desserts in separate bowls and according to the directions on the side of the box.  Put in refrigerator to set.  Have the Scouts crush the graham crackers into fine crumbs.  This can be done by putting the crackers in a zip-lock bag and having the Webelos pound the bag until the crackers are in very fine crumbs.

Mix the graham cracker crumbs with the melted margarine and granulated sugar. Press the mixture on the bottom and along the sides of the glass bowl to form a crust.  Set aside.

After two hours the gelatin will set. Spoon the black cherry into the graham cracker crust.  Form it so that there is about a five inch pocket in the middle.

Next, spoon in the lemon gelatin, leaving a two inch hole.  Into this center, spoon the raspberry gelatin.

Allow time for each Scout to take a look at the Earth Bowl and discuss its layers. Then dig in!
