In this final session, students reflect on how their understandings have grown and changed during the curriculum unit, and how they can apply their new understandings to water, air, and transformations of matter in the real world.

This opportunity for reflection is structured by having students focus on five models or investigations from the curriculum: the mini-lake, the spray mister, the 2-bottle system, the Particle Magnifier, and a syringe.

By the end of this investigation students will have had an opportunity to apply the new understandings they have developed about water, air, and the transformation of matter to real world situations.
