General Lesson Information
 Lesson Plan ID: 34414 Title: Gas Laws in the World of Aeronautics Overview/Annotation: Students investigate the properties of gasses using the gas laws and explore the application to aeronautics. This lesson is adapted from the NASA Education Guide Pushing the Envelope: A NASA Guide to Engines.  The activities used include the following:  Gas Laws (pg 27-28); Gas Law Problems - Boyle's Law (pg 29-30); Gas Law Problems - Charles's Law (pg 31-32); Gas Law Problems - Gay Lussac's Law (pg 33-34); Air Density (pg 61-62). This lesson was created as part of the 2016 NASA STEM Standards of Practice Project, a collaboration between the Alabama State Department of Education and NASA Marshall Space Flight Center.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 9-12 Chemistry 7 ) Plan and carry out investigations to explain the behavior of ideal gases in terms of pressure, volume, temperature, and number of particles. a. Use mathematics to describe the relationships among pressure, temperature, and volume of an enclosed gas when only the amount of gas is constant. b. Use mathematical and computational thinking based on the ideal gas law to determine molar quantities. Unpacked Content Scientific And Engineering Practices:Planning and Carrying out Investigations; Using Mathematics and Computational ThinkingCrosscutting Concepts: Scale, Proportion, and Quantity; Energy and MatterDisciplinary Core Idea: Matter and Its InteractionsEvidence Of Student Attainment:Students: Plan an investigation, considering the types of data, how much data, and accuracy of data needed to produce reliable measurements. Evaluate investigation design to determine the accuracy and precision of the data collected, as well as limitations of the investigation. Use evidence from investigation to explain the relationships among pressure, volume, temperature, and number of particles in a gaseous system. Mathematically describe the relationships of pressure, temperature, and volume of an enclosed gas, when only the amount of gas is constant. In terms of the ideal gas law, determine molar quantities using mathematical and computational thinking. Analyze, represent, and model data related to the gas laws using mathematical and computational thinking.Teacher Vocabulary:Pressure Volume Temperature Number of particles System Atomic/ molecular level Macroscopic level independent variable Dependent variable controlled variable(s) Direct proportional/ relationship Inverse proportional/ relationship Avogadro's Law Boyle's Law Charles' Law Gay-Lussac's Law (Amontons' Law) Ideal gas law ConstantKnowledge:Students know: Behavior of gases is determined by the movement and interactions of the particles. Relationships among the variables (pressure, volume, temperature, number of particles) can be used to predict the changes to a gaseous system. The movement and interactions of gas particles within a system and the type of sytem determine the behavior of gases. Relationships among the variables (pressure, volume, temperature, number of particles) can be used to predict the changes to a gaseous system.Skills:Students are able to: Plan an investigation that describes experimental procedure, including how data will be collected, number of trials, experimental setup, and equipment required. Conduct an investigation to collect and record data that can be used to describe the relationship between the measureable properties of a substance and the motion of the particles of the substance. Analyze recorded data to explain the behavior of ideal gases in terms of pressure, volume, temperature, and number of particles. Identify relevant components in mathematical representations of the gas laws. Analyze data using tools, technologies, and/ or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims. Use mathematical representations to determine the value of any relevant components in mathematical representations of the gas laws, given the other values.Understanding:Students understand that: Scientists plan and conduct investigations individually and collaboratively to produce data to serve as the basis for evidence. Changes in the variables that affect the motion of gas particles can be described and predicted using scientific investigations. The patterns of interactions between particles at the atomic/ molecular/ particulate level are reflected in the patterns of behavior at the macroscopic scale. Cause and effect relationships may be used to predict phenomena in natural or designed systems. Mathematical representations of phenomena are used to support claims and may include calculations, graphs or other pictorial depictions of quantitative information. Changes in the variables that affect the motion of gas particles can be described and predicted using scientific investigations. Cause and effect relationships may be used to predict phenomena in natural or designed systems.AMSTI Resources:ASIM Module: Calcium Carbonate Decomposition AP Boyle's Law Ideal Gas Law and Molar Volume 7a. & 7b. Emphasis is placed on the relationships between gas variables in the gas laws. Mathematical thinking is emphasized over memorization and algorithmic problem-solving.
