𝗕𝗔𝗟𝗜𝗧𝗔 | NSED kontra “The Big One”, nilahukan ng PDMHS

Matagumpay na nakibahagi ang President Diosdado Macapagal High School (PDMHS) sa ginanap na 4th Quarter Nationwide Simultaneous Earthquake Drill (NSED), sa tulong ng pakikipag-ugnayan sa pamunuan ng Barangay Katuparan upang palakasin ang kahandaan ng pampublikong paaralan sa posibleng sakuna.

Pinangunahan ni G. John Ray Mendoza, School Disaster Risk Reduction and Management (SDRRM) Coordinator, ang nasabing drill katuwang ang iba’t ibang organisasyon ng paaralan upang matiyak ang maayos at ligtas na pagsasagawa nito.

Sa panayam kay G. Rodolfo Bedejo, Barangay Security Force Assistant Team Leader, kanyang sinabi na isinagawa ang earthquake drill upang masiguro ang kahandaan ng lahat sakaling tumama ang hindi inaasahang “The Big One” na tinatayang aabot ng 7.2 magnitude.

“Pero kung sakali mang tumama, siyempre, handa ang buong barangay sa anumang posibleng mangyari,” pagbibigay-diin ni G. Bedejo.

Samantala, naglaan ang pamunuan ng Barangay Katuparan ng mga ambulansya, medic, at responders para sa isinagawang earthquake drill ng paaralan na ginanap nitong Huwebes, Nobyembre 6, ganap na alas-nuwebe ng umaga.

What day is it?🤔✨ IT'S WORDY WEDNESDAY!!✨

Did you know that the earth's orbit around the sun is not CIRCULAR but actually ELLIPTICAL?

We may notice sometimes when looking at solar system models, at first glance, planetary orbits appear to be perfect circles. But in reality, they are actually an ellipse—slightly stretched or elongated.

This is according to Johann Kepler's discovery; it is described in his First Law of Planetary Motion, also called the Law of Ellipses. This law explains why the earth and other planets are orbiting the sun in a path described as an ellipse with the sun at one of the two focal points (foci).

For a planet's orbit to be in a circular shape, its eccentricity must be 0. While for an ellipse, it must be between 0 and 1. The parabola and the hyperbola are the other two shapes. A parabola has an eccentricity of 1, whereas a hyperbola has an eccentricity larger than 1.

Currently, Earth's orbital eccentricity is around 0.0167, which is very close to zero. That’s why the orbit appears perfectly round to us—but it's still nearly circular and technically an ellipse.

Additionally, in a cycle that lasts roughly 100,000 years, Earth's eccentricity is currently decreasing extremely slowly and getting closer to its least elliptic (most circular) due to gravitational interactions.

Techy Tuesday! 📱⚡

Ever heard the myth that “Charging your phone overnight ruins the battery.”? ❌ Let's bust it!

Modern phones are kinda smart — once they hit 100%, they stop juicing up. ✅ So don’t worry, your phone won’t instantly die just ‘cause you left it charging while you sleep like most people think.

BUT 👀 there’s still catches!

• Your charger still sips a little power (aka phantom energy) wasting energy. ⚡

• If you do it all the time for months/years, your charger might give up faster because it will reduce the charger's life span leading to more e-waste... ♻️

• And yep, that tiny wasted energy still adds up for the planet 🌍

So no need to panic if you charge overnight once in a while — but being mindful helps your phone, your safety, and even the environment. 🌱

Remember; charge smart, not hard. 😉

𝗦𝗘𝗟𝗟𝗔𝗚 🌕

𝟭𝟲 𝗡𝗔 𝗢𝗥𝗔𝗦 𝗡𝗔 𝗟𝗔𝗡𝗚 𝗕𝗔𝗚𝗢 𝗔𝗡𝗚 𝗘𝗖𝗟𝗜𝗣𝗦𝗘! Halos araw-araw ay nakikita natin ang pag-iiba ng 'hugis' ng naliliwanagang bahagi ng buwan na pinakamalaki tuwing Full Moon. Matingkad man, ang buwan ay walang taglay na liwanag mismo kundi ito ay repleksyon lamang ng liwanag galing sa araw.

Hango mula sa Ilokáno, ang sellag (Inlges: moonlight) ay tumutukoy ay nakakabighaning liwanag mula sa buwan. Bukod sa kaaya-ayang itsura, ang sellag ay mahalaga ring gabay sa mga manlalakbay tuwing gabi at batayan sa pangingisda.

Tayo’y magkaisa sa pagtingin sa himpapawid at mamangha sa pamumula nang buwan ng may kaalaman at kasiyahan bilang mga “𝙆𝙤𝙣𝙚𝙠𝙩𝙖𝙙𝙤𝙣𝙜 𝙢𝙖𝙢𝙖𝙢𝙖𝙮𝙖𝙣 𝙨𝙖 𝙞𝙡𝙖𝙡𝙞𝙢 𝙣𝙜 𝘽𝙪𝙬𝙖𝙣!” ngayong darating na Setyembre 7-8, 2025! 🔴
