Investigating States of Matter
Kinetic and Potential Energy, and Arrangement of Particles
Vincent Hey and Yolanda Underwood
Goals and Objectives
To determine the differences in the spacing of particles in states of matter.
To determine the effect of temperature changes in kinetic and potential energy.
To determine the effects of temperature on the arrangement of particles
To determine the change in velocity distribution when the temperature is changed on a solid, liquid, or gas.
Intended Audience
Physical Science and Chemistry Students 9th –12th grades
Eager To Learn Eager To Learn ChemistryChemistry
Instructional Activities The teacher will lead a discussion
about the arrangement of particles in the states of matter.
A classroom discussion will be prompted by a short PowerPoint presentation.
(A few of the following slides could be used in the presentation).
Spacing within a Solid
The particles of a solid have a definite volume and definite shape.
Spacing Within A Liquid
A liquid has no definite shape but a definite volume.
The particles are usually farther apart than in a solid.
Spacing Within a Gas
A gas has neither a definite volume nor a definite shape.
It always fills any space available.
Additional Instructional Activities
Wet Labs/Demos to be used are:
Hot-Water Balloon The Fireproof
Balloon Temperature and
Kinetic Energy within States of Matter
Mr. Bry the Science Guy
Use of Simulab The students use a
modified simulab to reinforce the goals of this unit.
What is the relationship between velocity and kinetic energy?
Comparison of velocity and kinetic energy
(Snapshots of particles in motion)
Assessments
Students will engage in each of the following:
Class Discussions Lab reports Homework Quizzes
Resources Simulab Software and Textbook Conceptual Chemistry, by John

ConclusionThis institute has
been insightful and enlightening. The students are bound to learn many new concepts.
