Throwback holiday programme🔬💡 **STEM activities 假期活动**
今天，同学们一起探索**开关（Switch）的奥秘**！原来，我们平时轻轻按下墙上的开关，并不是魔法，而是里面的小贴片（接触片）接触后形成电路，电流才能顺利流通
平时按下开关，里面的接触片会连接电路，灯才会亮起来。✨
Today, our students explored the magic behind a light switch! They discovered that when we press a wall switch, the contact plate inside connects the electrical circuit, allowing electricity to flow and the light to turn on. ✨
