Engage your students in exploring why giant steel ships float while small rocks sink! This unit introduces key physical science concepts of mass, volume, and density through a hands-on, inquiry-driven approach. Students will: Investigate properties of matter: mass, volume, shape, and density Conduct simple tests to predict and explain sinking and floating Reflect on how engineers use matter’s properties to design floating structures Includes: ✅ Phenomenon reading with discussion and critical thi
