A model of matter and its motion Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Models of solids, liquids, an gases to show that adding or removing thermal energy increases or decreases kinetic energy of the particles until a change of state occurs. (examples of models are drawing, diagrams, 3D model, diorama) Pure substances are any element or compound Rubric Code: SXX42XC By kramin Ready to use Public Rubric Subject: Science Type: Project Grade Levels: 6-8

A model of matter
	Poor 1 pts	Fair 2 pts	Good 3 pts	Excellent 4 pts
Pure Substance	Poor The pure substance used is not identified or modeled correctly.	Fair The pure substance used is identified and modeled correctly part of the time.	Good The pure substance used is identified and modeled correctly through out the model. An element was chosen as the pure substance.	Excellent The pure substance used is identified and modeled correctly through out the model. A compound was chosen as the pure substance.
States of Matter	Poor All 3 states are modeled correctly, but no other details given.	Fair All 3 states of matter are modeled correctly. Some of the shape or volumes are labeled. Motion missing.	Good All 3 states of matter are modeled correctly. Shape and volume are labeled correctly. Motion of particles is excluded	Excellent All 3 states of matter are modeled with the correct structure, labeling the shape and volume of each state. The motion of the particles is described.
Thermal and Kinetic Energy	Poor Model describes thermal energy and kinetic energy, but not how the two relate to change the phase/state of matter.	Fair Model shows how a change in thermal energy changes the kinetic energy in a pure substance between some of the phases/states. No temperatures are given, no explanation of conservation of energy.	Good Model shows how a change in thermal energy changes the kinetic energy of the pure substance between each phase/state. A boiling point or a melting point is given. No explanation of conservation of energy.	Excellent Model shows how a change in thermal energy changes the kinetic energy of the pure substance between each phase/state. The boiling point and melting point for the pure substance is identified and explained. The Law of conservation of energy is explained.
