INTRODUCTION

Looking for a way to actively engage your students in learning about the Gas Laws? This module does just that for students enrolled in Chemistry I or Chemistry I Honors! In this module, students will explore the relationship of volume, pressure, and temperature on gases (Boyle's and Charles' Gas Laws).  Utilizing laboratory investigations and computational modeling techniques with Excel©, as well as many interactive learning strategies, students will study Boyle's and Charles' Laws. Students will graph and compare their lab data to the expected results of the model. Designed as a three-week unit (fifteen 50-minute class periods), it can easily be modified for a block schedule. 

MODULE OBJECTIVES

Teachers

After completing this module, students will learn and be able to do the following:

Ø      Learn the pressure of the atmosphere at sea level measured in atm, kPA, mmHg, torr, and psi.

Ø      Convert one pressure unit into another.

Ø      Draw a P vs. V graph.

Ø      Manipulate P V data so a straight-line graph is obtained.

Ø      Form a mathematical law from a straight-line graph.

Ø      State Boyle’s Law.

Ø      Recognize other examples of Boyle’s Law.

Ø      Solve Boyle’s Law problems.

Ø      Draw a V vs. T graph.

Ø      Using a graph, determine a value for absolute zero.

Ø      State Charles’ Law.

Ø      Explain why temperatures must be in K.

Ø      Solve Charles’ Law problems.

Ø      Recognize other examples of Charles’ Law.

Ø      State the Combined Gas Law (P, V, T).

Ø      Explain Avogadro’s Law (V & n).

Ø      Identify the principal features of the Kinetic Molecular Theory of gases.

Ø      Be able to explain why each of the gas laws works in terms of the Kinetic Molecular Theory.

REQUIREMENTS

Prerequisite skills for student success include knowledge about the states of matter and their characteristics and previous experience using CBL (calculator-based laboratory) and graphing calculators.
