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:

ConclusionThis institute has

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