三月十二日是中国的植树节，《礼记》记载的 “孟春之月，盛德在木”，正是我国植树文化最早的注脚。在三月的微风中，杭校小学部也开启了一系列的植树节主题活动。

植树节的 “生日”与中国一位伟大的领袖人物息息相关——3月12日是孙中山先生逝世纪念日，他生前曾大力倡导植树造林。其实早在西周时期，我国就有"清明插柳"的传统。放眼世界，如今全球50多个国家都有自己的植树节：美国各州有独立植树日，日本把4月3日定为"绿之日"，印度7月的雨季更是全民植树的热潮。而在中国，这个节日不仅是播种的仪式，更承载着“前人栽树，后人乘凉”的古老智慧。

晨雾中婆娑的梧桐，暮色里挺拔的雪松，这些绿色卫士默默奉献着惊人价值： 1棵大树1天可为4人输送氧气，20平方米的树林能吸收一辆汽车行驶16公里排放的尾气。它们更是水土保持的天然屏障——1公顷林地可比裸地多储水3000立方米。当孩子们抚摸着校园里粗糙的树皮时，仿佛触摸到了地球跳动的脉搏。

三月的第四周，杭校的校园中跃动着欢快的生机。老师们为一年级 "田园小当家"们在教学楼旁准备了小小“种植角”。萌娃们或三五成群，或乖巧地排好队伍，用迷你铲子小心翼翼地为菜苗培土。"我的白菜宝宝要喝饱水！"孩子们种完种子还不忘给种子浇上满满一壶水。

二三四年级 "小小环保大使"们在老师的带领下，完成了植树标语的制作。课堂中同学们了解了植树节的由来以及各个国家植树节的活动以及植树节相关的趣闻，共同探讨了“如果我们的树木遭到破坏，我们失去了树林、森林，会有什么后果？” 稚嫩的声音迸发出深刻的思考："小鸟会无家可归。"，"地球会像干裂的苹果。"，"沙尘暴会吞没城市"。最终，孩子们将环保意识转化为实际行动，用五彩画笔在再生纸上绘制出充满童趣的标语——"我给小树当保镖。"，"每片绿叶都是地球的微笑。"，“More trees,more life.”,“种一棵大树，造一处美景。”，“One tree,one beauty in your eyes.”稚嫩的笔尖流淌出对自然的深情告白。

活动结束时，当同学们再次凝望着白板上跃动的绿色诗行 ——那些用稚嫩笔触勾勒的绿色宣言，在智慧碰撞的火花中愈发鲜亮。此刻无需春泥的陪护，简单的一次班会课，已让环保的嫩芽在童心里悄然抽枝。或许这正是植树节最诗意的注脚：每双小手都愿为春天添一抹新绿，希望便会在年轮里永远生长。

March 12th marks China’s Arbor Day, rooted in the ancient wisdom of the Book of Rites: "In early spring, virtue lies in trees." Amid the gentle breezes of March, the school’s primary section launched a series of Arbor Day-themed activities.

1. The "Green Code" of Arbor Day

Arbor Day’s date is tied to Dr. Sun Yat-sen, a pioneer of afforestation in China, as March 12th commemorates his passing. China’s tree-planting traditions trace back to the Western Zhou Dynasty with the custom of "planting willows during Qingming." Globally, over 50 countries celebrate their own Arbor Days: the U.S. has state-specific dates, Japan honors April 3rd as "Greenery Day," and India embraces tree-planting during July’s monsoon season. In China, Arbor Day symbolizes not just planting but also the enduring wisdom of "planting trees for future generations to enjoy the shade."

2. Silent Guardians of Nature

From dawn’s misty plane trees to dusk’s towering cedars, these green sentinels offer immense value: A single large tree provides oxygen for four people daily, while 20 square meters of trees absorb exhaust from a car driving 16 kilometers. Forests also protect soil and water—1 hectare of woodland stores 3,000 cubic meters more water than bare land. When children touch the rough bark of campus trees, they feel the pulse of our living planet.

3. Joyful Eco-Actions

During March’s fourth week, the campus buzzed with youthful energy. First graders became "Little Gardeners," tending to a mini planting area. With tiny shovels, they carefully nurtured seedlings, cheering, "My cabbage baby needs plenty of water!"

Older students (Grades 2-4), as "Eco-Ambassadors," crafted tree-themed slogans after learning about Arbor Day’s global significance. They pondered: "What if forests disappeared?" Answers ranged from "Birds would lose homes" to "Earth would crack like a dried apple." Their creative slogans, painted on recycled paper, declared: "Plant a tree,save a life.", "Every green leaf is Earth’s smile." ,"More trees, more life." “One tree,one beauty in your eyes.”and so on.

4. Many Ways to Protect Green

As the activity concluded, students gazed at their vibrant eco-slogans on the whiteboard. Through simple classroom discussions, sprouts of environmental awareness took root in young hearts. This embodies Arbor Day’s poetic essence: when tiny hands add new green to spring, hope grows eternally with each tree’s rings.
