The Philippines has a total of 300 Volcanoes, 22 are active and the rest are inactive or dormant.

The two most active and always in the news are Taal and Mayon.  Taal in 2020 erupted and affected more than a 700 thousand people, damaged million pesos infrastructure and livelihoods, and caused disruption of essential services in CALABARZON, Regions III, IV A, and NCR.  The most recent eruptions happened in March and April this year 2022.

Taal, in its serenity, is an “instagrammable” sight, but can turn into “beastful” mode when it erupts, destroying all in its surrounding.

To teach the science behind volcanoes, B2B Teacher Malaya, Atong, and Aram first Pan-Venture with their real-life Grade 10 classmates from St. Genevieve School of Pateros begun with the lesson on Volcano titled, Volcanic Eruptions: When Beauty becomes the Beast, webcast last 11 April 2022.

NRCP Researcher – Scientist, Dr. Mylene M. Villegas, who is also the Chief of the Geologic Disaster Awareness & Preparedness Division of DOST Philippine Institute of Volcanology and Seismology (PhiVolcS) served as webisode teacher.


Teacher Mylene opened the discussion by describing volcano as a hill or a mountain with fissure vent or opening where molten rocks or gaseous materials are ejected.  She also shared information on the properties of volcano and different volcanic hazards, their characteristics and their impacts to the environment including human and animal lives.

In the online experiment she performed, Teacher Maylene demonstrated the thickness of magma using water, toothpaste, and syrup.  Among the materials, she said that the thickness of magma can be compared to the toothpaste which is the hardest to stir compared to water and syrup.  Magma is one of the components of volcanic eruption.

Dr. Karlo L. Queaño, Chair of NRCP Division of Earth and Space Sciences, who served as the class moderator, encouraged the online students to keep on being curious and to study science because it is very important for nation building.  He hoped that someday, some if not all of the online students would be volcanologists who could help the people in case a volcano erupted, like Mt. Pinatubo.


B2B online science class Principal and NRCP Executive Director, Dr. Marieta Bañez Sumagaysay, in closing the lesson said that the simple experiment helped students understand the beast part of the beautiful volcanoes. This lesson provided them with new knowledge like the different characteristics and behavior of volcanoes, she added. Likewise, she hoped that the SGSP students and public will have more fun doing and sharing the experiments to their classmates, friends, and families, with proper guidance of science teachers.
