This document discusses whether science should be taught stand alone or embedded within other units in a PYP curriculum. It considers if inquiry alone is enough to teach science or if dedicated science lessons are needed. Some examples are provided of science lessons that were either embedded in a unit about castles or a stand alone lesson on buoyancy. The conclusion is that inquiry itself prepares students for the real world, and as long as lessons encourage hands-on experience and inquiry, either approach to teaching science through embedded or stand alone lessons is valid.
