The main parts of a volcano include the magma chamber, conduits, vents, craters and slopes. There are three types of volcanoes: cinder cones, stratovolcanoes and shield volcanoes.
Put a pile of baking soda on the baking sheet. Put a small amount of vinegar in the cup and add a drop or two of food coloring. Have your child use the spoon or eye dropper to drop (or just pour) a little vinegar solution onto a pile of baking soda and watch your volcano erupt!
For more of a contained mess try this Volcano:
Place the cup in the middle of the pan. Tear a large sheet of aluminum foil to cover the cup and lay at the bottom of the pan, creating the shape of the volcano. Poke a medium-size hole through the aluminum foil above the cup. This is where your volcano will erupt.
Use the Blazerod (Cylinder 3,1) for minor detail work. Once you have the shape of the “volcano” present, start using the Feather (Smooth 3), Starting at the base. In quick motions, smooth from Base to Peak all the way around the cone. Once you get the shape of the volcano you desire, you’ll need to carve the caldera.
Take one square of toilet paper and put 1 tbsp. baking soda in the middle of it. Roll it up and twist the ends to enclose the baking soda. When you are ready to present the project, drop the baking soda packet into the volcano, and watch it erupt.
Use one part glue to one part water; the exact amount depends on how much lava goo you need for the project. Stir in the Borax 1 tablespoon at a time until the mixture becomes a gooey substance that holds together. Add a few drops of food coloring to the container. Add 4 tablespoons of baking soda to the mixture.
What to do. Fill the glass about 3/4 full of water . Add about 5 drops of food coloring – I like red for the lava look. Slowly pour the vegetable oil into the glass.
The three main parts of a volcano are the chamber, the vent, and the crater. The chamber is where the magma is stored.
A cross section of a composite volcano reveals alternating layers of rock and ash: (1) magma chamber, (2) bedrock, (3) pipe, (4) ash layers, (5) lava layers, (6) lava flow, (7) vent, (8) lava, (9) ash cloud. Frequently there is a large crater at the top from the last eruption.
Pour warm water and red food coloring into the volcano bottle until filled to the top. Add liquid detergent and baking soda. Pour vinegar in and take a couple steps back. The chemical reaction of the baking soda and vinegar will cause the “lava” to spew from the volcano.
First, add the water, vinegar, detergent and food coloring to your water bottle. Do NOT add the baking soda at this point. Put your bottle in a muddy spot and build the mud volcano around the bottle without getting mud into the opening of the bottle. When you’re ready, add the baking soda.
