PHYSICAL SCIENCE: DENSITY & BOUYANCY http://sn.im/ac-science-densityThis unit was developed for 8th graders by a team of Oakland CAteachers working to develop an inquiry-based curriculum. They write:"Density is a difficult concept for middle school students to grasp.They begin with the idea that things are heavy or light. They havenot really thought about weight in relationship to the volume of anobject. Our task in this sequence is to build their understandingthrough a series of experiments and investigations, driven by thestudents' curiosity."
