While various geologic events disrupt activities in populated areas, they offer an opportunity for educators in the earth sciences to integrate them in their classroom teaching. This paper presents an integrative geologic event class activity which incorporates details relating to the recent 2020 eruption of the Taal Volcano in the Philippines. The first part of the lesson design format consists of experiential narrative that will come from the student participants and is correlated with highlight events from the eruption. This part allows the learners to own the activity as they are engaged in the event which they directly or indirectly experienced. The second part proceeds to involve the students scientifically in terms of analysing samples (in this case, collected volcanic ashes) from the eruption. Sub-activities here include recording of naked-eye observations of the sample, feature analysis and comparison using a loupe and a portable optical microscope, and tabletop physical characterizations. This in-class or laboratory activity is designed to accommodate actual and remote conduct. It is envisioned that early integrated science educators can use the design format to fit their activities based on the geologic events they experience in their respective places.
