This experiment involved observing the chemical reaction between an acid and a base, resulting in a vibrant display of bubbles. Additionally, the activity provided an opportunity for students to understand the concept of density by working with various liquids.
🧪製作熔岩燈 - 科學課🌟
七年級學生進行了有趣的實驗:製作熔岩燈。
這項實驗需要觀察酸鹼之間的化學反應,才能造就劇烈的反應,產生大量泡沫。學生也從實驗中學習到透過不同液體的特性來理解密度的概念。
