KENTUCKY (May 14th – 20th – Bubbling Magma)


• Clear Plastic cup
• Vegetable Oil
• Red Food Coloring
• Water
• Alka-Seltzer


STEP 1: Fill the clear plastic cup ¾ of the way with vegetable oil.
STEP 2: Fill the rest of the clear plastic cup with water.
STEP 3: Add several drops of red food coloring.
STEP 4: Break the Alka-Seltzer into smaller pieces. Add the pieces to the
bottle and observe. What happens? Describe how this can be used as a
model to better understand the movement of magma to Earth’s surface.


Oil and water do not mix. The oil stays above the water, since it is less dense
than the water. When you add the Alka-Seltzer, it sinks to the bottom,
dissolving in the water, creating a gas. The rising, gas filled, blobs of water
push through the oil layer, to the top. Once at the top, the gas escapes and
the blobs of water sink back to the bottom.


A volcano is a vent in Earth’s crust through which melted or molten rock
flows. Molten rock below Earth’s surface is called Magma. The red water
represents the magma. Magma moves toward Earth’s surface because it is
less dense than Earth’s crust. The blobs of red water are less dense, since
they contain carbon dioxide gas, created from the Alka-Seltzer, dissolving in
the water. The blobs of red Molten rock that erupts onto Earth’s surface is
called lava.

• Use information from several sources to provide evidence that a
volcanic eruption can occur quickly or slowly.
• Generate and compare multiple solutions to reduce the impacts of a
volcanic eruption on humans.


PLEASE follow these safety precautions when doing any science experiment.

• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything while doing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons,
and other small parts. Those objects could become a CHOKING
HAZARD. Adults are to perform those experiments using these
objects. Any child can choke or suffocate on uninflated or broken
balloons. Keep uninflated or broken balloons away from children.

Our “science guy” Jason Lindsey has his lab coat and safety shield on, he says he is working on an experiment with a fireball and an explosion.
