 8th Graders Explore Physical Properties and the Conservation of Mass

Our 8th grade scientists have been busy bringing science to life through hands-on learning. In recent labs, students explored the physical properties of matter by observing and measuring various materials—using mass, volume, density, and sensory data to identify what makes substances unique. These foundational skills build confidence and prepare students for more advanced science courses and real-world problem-solving.

Students then put their knowledge into action with a glow stick lab to test the law of conservation of mass. By measuring glow sticks before and after activating the chemical reaction, students discovered that while energy and appearance may change, mass remains constant. The visual, engaging experiment made an abstract concept both memorable and meaningful. “These labs help students deepen their understanding by actually doing science,” said middle school science teacher Nicole Schatzle. “They’re not just reading—they’re observing and drawing their own conclusions.”

At JPII, inquiry-based learning and exploration are at the core of what we teach. These lessons encourage critical thinking, curiosity, and a deeper appreciation for how science connects to everyday life.  “When students see science in action,” added Mrs. Schatzle, “they become more engaged and excited to learn.”

Through these experiences, our 8th graders continue to grow as thoughtful, motivated learners—well-prepared for future STEM challenges and inspired to understand the world God created.
