𝙔𝙀𝙎-𝙊 𝙁𝘼𝘾𝙏: 𝙒𝙤𝙧𝙡𝙙 𝙍𝙖𝙞𝙣𝙛𝙤𝙧𝙚𝙨𝙩 𝙒𝙚𝙚𝙠

This week, we are celebrating World Rainforest Week. Our forests serve as the lungs of our planet. It is important for the production of clean air and as habitats for animals.

Take a look at the pictures below as to how our YES-O officers and members spent time in the forests and to learn about this important environment activity.

Wildlife is not separate from human life—it completes the circle of existence.

Last October 1-7, Word Wildlife Week was conducted. That week focused on protecting and preserving the world's diverse wildlife.

𝙍𝙀𝘿 𝙁𝙇𝘼𝙂 𝙨𝙚𝙘𝙩𝙞𝙤𝙣𝙨 - 𝙞𝙨𝙖 𝙗𝙖 𝙠𝙖𝙮𝙤 𝙧𝙞𝙩𝙤?

Mukhang sermon ni Class Adviser ang sasalubong sa Monday ng mga red flag section na ito bukas.

Sa YES-O, red 🚩 means hindi nakakaganda ng school environment! Kaya naman iwasan nating ma-label as red flag at ugaliing maglinis ng room.

Ang YES-O SCAN o School Cleanliness and Neatness Patrols ay laging nariyan para mag-ikot at mag-inspect ng room, kaya 'wag pumayag na ma-tag kayo as red flag. Linisin ang loob at labas ng room, at magsegregate ng basura. It's not just a room, it's your responsibility.

Important Note: Ang YES-O Scan ay isinasagawa araw-araw pagkatapos ng last period sa umaga o sa hapon. Minsan surprise! Ang record na ipinost ay mula sa nakalap na pagpapatrol mula September 22-October 16. Ang mga red flag na section ay ang mga may record ng pito o higit pang hindi malinis na classroom o area.

Dahil kailangan na raw ihanda ang mga BALDE para sa paparating na Super El Niño, nag-instila na ng mga Rainwater Catcher Drum ang Mambangnan National High School mula sa inisiyatibo ng YES-O ng paaralan katuwang si Ma'am Rowena Palma, punong-guro.

Ang mga balde ay nakakonekta sa roof gutter ng mga gusali ng paaralan upang makakolekta ng tubig ulan na maaaring gamiting panlinis o pandilig. Ito ay makatutulong sa pagtitipid sa tubig ng paaralan.

Water conservation at its finest! Kaya naman BBM na kami - Balde-Balde nang Makatitipid sa tubig!
