Original Prompt6-PS1-4 4. 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. [Clarification Statement: Emphasis is on qualitative molecular-level models of solids, liquids, and 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 could include drawing and diagrams. Examples of particles could include m...
This learning resource focuses on the concepts of thermal energy and particle motion at a molecular level. Students will explore how changes in thermal energy affects particle motion, temperature, and the states of pure substances, such as solids, liquids, and gases. The document includes a 'Particle Behavior Organizer' that outlines how particles behave in different states, with accompanying drawings for each state. Through questions and modeling challenges, students will justify their understanding of kinetic energy and make predictions about how adding or removing thermal energy can change a substance's state. Critical thinking scenarios encourage deeper exploration of concepts like sublimation and deposition.
