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 9 th –12 th grades Eager To Learn Chemistry

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

Conclusion This institute has been insightful and enlightening. The students are bound to learn many new concepts. Thank you. Yolanda & Vinny
