Thank you, Dr Calvin YM Lam, for his brilliant presentation, which explained the urgency of reducing carbon emissions in a clear and accessible way. Through Dr Lam’s professional guidance, the children are no longer just hearing the word “environment,” but have deepened their environmental awareness. During the “solar‑powered tiny house” activity, everyone displayed boundless creativity and teamwork! Watching the delicate tiny houses rotate and generate electricity under the sun, the children’s amazement is the finest illustration of the promise of green energy.
