STEM Exhibit: Where ideas spark✨ science shines, and the future begins! ⛅

Our STEM exhibit is more than just a showcase—it’s a journey of discovery, creativity, and innovation. Every project presented here is a product of curiosity, hard work, and teamwork. Through science, technology, engineering, and mathematics, we explored real life problems and searched for meaningful solutions. This exhibit reminds us that learning goes beyond the classroom it’s about applying knowledge to create something useful, inspiring, and impactful. Together, let’s celebrate the power of STEM in shaping a better future! 🌍🔬✨⚡

Heads up, skywatchers! 🔭

One of the most anticipated annual events for skywatchers, the Perseid meteor shower, will peak and be visible in Philippine skies on Tuesday evening, state weather bureau PAGASA said.

📐💡 Here’s a fun math moment for today:
07/24/25 is a Pythagorean triple!
Why? Because 7² + 24² = 25² → 49 + 576 = 625 ✅

Even cooler? This works no matter where you are, since addition is commutative: 24/07/25 works too!

We love seeing math show up in surprising ways.

KNOW YOUR HAZARDS ⚠️⚠️⚠️

How to use HazardHunterPH to check your susceptibility level to flood due to and low pressure area (LPA):
1. Go to hazardhunter.georisk.gov.ph.
2. Click "Current Location."
3. Scroll down the right panel for "Flood (MGB)." Possible flood levels and duration are stated in the assessment summary.
4. To search for other possible flooded areas, go to the left panel and click Hazards -> Hydro-meterological -> Flood (MGB)

🌋 Distinct Features of Volcanoes: Volcanoes have several distinct features that form due to the movement of molten rock (magma), gases, and other materials from beneath the Earth's surface. These features vary depending on the type of volcano and the nature of the eruption. Here's an overview of the different features of a volcano:

✅️ 1. Magma Chamber

Location: Beneath the surface.
Description: A large underground pool of molten rock. It is the source of magma that rises during an eruption.
Function: Feeds magma to the volcano during eruptions.

✅️ 2. Vent

Location: Central or side opening on the volcano.
Description: The opening through which magma, gases, and ash escape to the surface.
Types:
Central Vent – Main opening at the summit.
Secondary/Side Vent – Smaller outlets on the flanks of the volcano.

✅️ 3. Crater

Location: At the summit.
Description: Bowl-shaped depression around the central vent.
Formation: Formed by explosive activity or collapse after eruptions.

✅️ 4. Caldera

Location: Larger depression at the summit.
Description: A massive, basin-like hollow formed when the magma chamber empties and the ground collapses.
Example: Yellowstone Caldera, USA.

✅️ 5. Lava Flow

Description: Molten rock that flows from the vent during an eruption.
Types:
Pahoehoe Lava – Smooth, ropy surface.
Aa Lava – Rough, jagged, and crumbly surface.

✅️ 6. Ash Cloud

Description: A cloud of volcanic ash and gases that rises into the atmosphere.
Impact: Can cause air travel disruptions and health hazards.

✅️ 7. Volcanic Cone

Description: The mound built by successive eruptions of lava, ash, and other volcanic material.
Types:
Shield Cone – Broad, gently sloping (e.g., Mauna Loa, Hawaii).
Composite Cone (Stratovolcano) – Steep-sided, layers of lava and ash (e.g., Mount Fuji).
Cinder Cone – Small, steep, built of ash and cinders (e.g., Parícutin, Mexico).

✅️ 8. Fumaroles

Description: Openings that emit steam and volcanic gases (like sulfur dioxide).
Often found: Near craters or lava domes.

✅️ 9. Lava Dome

Description: Rounded mound formed by slow eruption of viscous lava.
Example: Mount St. Helens Lava Dome, USA.

✅️ 10. Pyroclastic Flows

Description: Fast-moving currents of hot gas, ash, and volcanic matter.
Danger: Extremely deadly due to high temperature and speed.

✅️ 11. Dikes and Sills (Intrusions)

Dikes: Vertical sheets of magma that cut through rock layers.
Sills: Horizontal sheets of magma that spread between rock layers.
Visible in: Eroded volcanoes or exposed rocks.
