Introduction
Chemical reactions are a daily part of our lives. When
we burn firewood, the brown wood has a chemical reaction
and changes into ash. When you bake a cake, the liquid
batter chances into something solid, fluffy or spongy.
Chemical reactions, however, cannot be reversed. Whenever
a substance changes its form it cannot be change back
to its original state. In this activity, you get the
chance to create your own chemical reaction!
Purpose
•
Reinforcement of curriculum in Science
• Participate in Science activities and discussion
Time
This
activity will take 45 minutes to an hour.
Materials
•
Paper cup
• Paper
• Paint
• Piece of cardboard
• 1/3 cup Baking soda
• 1/3 cup Vinegar
Directions
•
Wrap the outside of the paper cup with butcher paper
and color or paint the outside. You can decorate the
paper cup before you wrap it around the cup. Staple
or tape the paper around the cup so that your cup is
inside the paper cone. (You may need to cut the paper
to make this work)
• Using a large piece of cardboard, create a base
and attach to the bottom of your volcano.
• Place 1/3 of a cup of baking soda into the volcano’s
center.
• Measure out 1/3 cup of vinegar and carefully
pour the vinegar into your volcano.
• Observe the reaction!

If your Dreamer is interested in volcanoes, try watching
Ring
of Fire (1991), a movie that features spectacular
photography of volcanoes around the Pacific Rim.

• The science behind it:
Chemical reactions occur when two or more molecules
react to form something new. The type of chemical reaction
that occurred is called neutralization reaction. The
vinegar is a weak acid, while baking soda is a strong
base. When you put a base and an acid together, they
neutralize each other in a reaction and form neutral
water.
