๐Ÿ”ฌ Mass Mysteries Unveiled: Exploring the Law of Conservation in Chemistry ๐Ÿงช๐Ÿ”ฌ

Last week in Mr. Teoh's Grade 10 Chemistry classes, students engaged in hands-on experiments to explore the Law of Conservation of Mass. By observing reactions like copper sulfate with sodium hydroxide, baking soda with vinegar, and burning steel wool, they learned that the total mass remains constant even when substances change. This exciting, interactive approach not only deepened their understanding of fundamental scientific principles but also sparked curiosity and critical thinking skills essential for their growth as young scientists. ๐Ÿงซ๐Ÿ’ก
