Volcano Model and Volcanic Eruption (EARTH SCIENCE)
Most Essential Learning Competencies:
The learner shall be able to:
 describe the different types of volcanoes and volcanic eruptions,
 explain what happens when volcanoes erupt; and
 illustrate how energy from volcanoes may be tapped for human use.
Objectives:



Create a model of volcano using basic tools and ingredients.
Illustrate the process involved in volcanic eruption.
Compare and contrast the volcanic eruptions produced by different substances
Materials:

Procedure:
For the Volcanic Eruption
1. Using the stirring rod, mix ¼ cup water, 1 tablespoon baking soda, 6mL liquid detergent,
and three drops of food coloring in a cup.
2. Pour the prepared mixture into the mouth of your volcano.
3. Slowly pour vinegar into the bottle and watch how furious your volcano is. Record your
observations.
4. Clean area for another experiment.
5. Repeat step 1.
6. Put 5 mentos candy inside the volcano and slowly pour 1 bottle of coke.
7. Repeat step 4.
8. Add yeast into the mouth of volcano.
9. Mix 20mL cup of hydrogen peroxide and food coloring.
10. Pour hydrogen peroxide into the mouth of your volcano.
