澳大講座提升中學生科學熱情

澳門大學健康科學學院助理教授曾華鑫和濠江學者李俊樂分別於新華中學及慈幼中學進行了兩場題為“細胞之美”和“從數學去了解我們的心跳”的科學講座,藉此提升中學生對科學、生物、醫學等領域的興趣。

曾華鑫向學生展示了一系列細胞圖像,並指出成像技術的進步讓人類看清細胞細節。他還介紹了細胞器的作用,說明細胞是生物體的基本單位,研究細胞運動有助今後深入探索相關領域。

李俊樂以問答形式引入主題,向學生科普史上首張心電圖源自老虎狗。他指出心臟就像人體的機械泵,向全身輸送氧氣、二氧化碳和其他營養物質;並進一步展示和解釋心臟中有超過50億個肌肉細胞通過電信號來適時協調收縮序列,以及透過心電圖檢測心臟細胞動作電位以觀察患者心臟健康的機制。

講座中,同學們表現非常投入,並積極向講者提出多個生物醫學和學院課程相關的問題,講者則以生動有趣的方式解答學生的問題,並以真實例子向學生們展示相關知識,互動交流氣氛熱烈。

澳大健康科學學院科學講座已持續舉辦多年,旨在以深入淺出的方式向中學生分享科學、生物、醫學的奥妙,從而提高他們對相關領域的興趣,引導和培養他們的科學熱情。

UM holds science talks to enhance local secondary students’ passion for science

Assistant Professor Chang Wa Kam and UM Macao Fellow Lei Chon Lok in the University of Macau (UM) Faculty of Health Sciences (FHS) delivered two science talks to enhance local secondary students’ interest in science, biology, and biomedical sciences. The former gave a talk titled ‘The Beauty of Cells’ at Escola Xin Hua, and the latter gave a talk titled ‘Modelling Life: The Mathematics of Our Beating Heart’ at Instituto Salesiano.

Prof Chang showed the students a series of cell images and pointed out that advances in novel imaging techniques enable humans to observe cells in detail. He then explained the role of organelles, the mechanism of how cells function as the basic unit of living organisms, and why studying cell motility would be beneficial for further studies on cells.

Dr Lei began his talk with a question and answer session, and told the students that the very first electrocardiogram (ECG) was performed on a bulldog. He said that the heart acts as a mechanical pump for the human body, pumping oxygen, carbon dioxide and other nutrients to the whole body through blood circulation, adding that the heart has more than five billion muscle cells that coordinate the sequence of contraction through electrical signals. He then explained the mechanism of observing the health of a patient’s heart by using an ECG to measure cardiac action potentials.

During the science talks, the students all showed great interest and raised questions related to biomedical sciences and the academic programmes offered by the FHS. The two speakers answered the students’ questions in a lively and interesting way and shared the relevant knowledge with real-life examples.

UM FHS has been organising science talks for many years, with the aim of sharing knowledge of science, biology, and biomedical sciences with secondary students in a lucid manner, thereby enhancing their interest in the related fields as well as their passion for science.
