Mr. McCready Demonstrates An Exothermic Reaction

Leave a comment

Students in Mr. McCready’s Chemistry class observed an exciting demonstration yesterday. The topic was exothermic reactions. In the video, Mr. McCready explains that heat is generated by dissolving zinc dust in water. The heat was enough to ignite the other chemicals, which caused a small explosion (in a safely controlled environment, of course!).

This demonstration is an example of the “hands on” learning that makes science a popular subject at Xaverian. In a time where digital technology is king, students are still drawn to the science labs and apparatus. Mr. McCready says that he’s “found a good balance between completely hands-on experiments, and computer-based experiments” in his curriculum.
