Chemical Change, Volume | Middle School, Elementary School

Lab: Air Bag Design Challenge

In this lab, students will learn how chemistry is used in air bags. Students will model the inflation of an air bag by performing a series of reactions using baking soda and vinegar in a Ziploc bag. During this investigation, students will see that there is a relationship between the inflation size of the bag and the amount of reactants used. Finally, students will be challenged to design an air bag that can help an egg endure a crash test.

Lab: Molar Mass of Butane

In this lab, students will experimentally determine the molar mass of butane using Dalton’s law and the ideal gas law. They will also calculate the percent error and explain possible sources of error.

Lesson Plan: Investigating Popcorn with the Ideal Gas Law

In this lab, students will collect data to determine the pressure inside a popcorn kernel when it pops using the Ideal Gas Law. They will also calculate the percentage of water present in the average popcorn kernel. This resource includes two versions of the student activity, traditional and inquiry.
Density, Physical Properties, Temperature, Gas Laws, Density, Pressure, Molecular Motion, Ideal Gas, Volume

Simulation: Density

The simulation for the September 2015 issue allows students to investigate the effect of changing variables on both the volume and the density of a solid, a liquid, and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively.
Gas Laws

Simulation: Gas Laws Simulation

The simulation for the November 2015 issue allows students to investigate three of the fundamental gas laws, including Boyle’s Law, Charles’ Law and Gay-Lussac’s Law. Students will have the opportunity to visually examine the effect of changing the associated variables of pressure, volume, or temperature in each situation. Also, students will analyze the gas samples at the particle level as well as manipulate quantitative data in each scenario. Finally students will interpret trends in the data by examining the graph associated with each of the gas laws.
Gas Laws, Stoichiometry, Mole Concept | High School

Lab: Investigating the Self-Inflating Balloon

In this lab, students will investigate the chemical reaction used in the self-inflating balloon. They will apply their knowledge of gas laws and stoichiometry in order to determine the quantities of reactants used to inflate the balloon.
Gas Laws, Pressure, Measurements, Molar Mass, Ideal Gas, Partial Pressure, Error Analysis | High School

Lab: Determination of the Molar Mass of Butane

In this lab, students will experimentally determine the molar mass of a gas, specifically butane (C4H10), by collection over water. This experiment is an inquiry based experiment for 2nd year chemistry or AP chemistry students who have previously collected an insoluble gas.
Gas Laws, Stoichiometry, Kinetic Molecular Theory, Ideal Gas, Partial Pressure | High School

Lab: Determination of the Ideal Gas Law Constant

In this lab, students will collect a gas sample over water and use multiple scientific principles including stoichiometry and gas laws to experimentally determine the Ideal Gas Law Constant (R).
Solubility, Temperature, Pressure, Concentration, Solute & Solvent | High School

Demonstration: Exploring Gas Solubility

In this demonstration, students will explore how changes in pressure and temperature affect the solubility of a gas in an aqueous solution. In addition, students will have the opportunity in a post-demonstration reflection activity to practice using data (in this case their demonstration observations) to make evidence based claims.
Density, Lab Safety, Combustion | High School

Demonstration: Density of Gases and Particle Diagrams

In this demonstration, students will observe the teacher carry out two combustion reactions. First the teacher will burn a small sample of propane gas in a beaker. Next the teacher will burn a small sample of methane gas. Students will create particle diagrams in order support their explanation and model their observations as they improve their understanding of gas density.
Kinetic Molecular Theory | High School

Demonstration: Diffusion of Particles

In this demonstration students will experience diffusion, and then model the process of diffusion of microwave popcorn “flavor particles” in a room filled with still air.
Gas Laws, Pressure, Volume | High School

Lab: Deriving the Gas Laws

In this lab, students will investigate the relationships of the variables related to gases. They will draw particle diagrams and derive equations to express these relationships. They will then combine these relationships to derive the combined gas law and the ideal gas law. Finally, they will use the molar volume of a gas at STP to derive the ideal gas constant, R.
Gas Laws, Pressure, Kinetic Molecular Theory, Volume | High School

Demonstration: Inflate and Shrink Wrap a Student

In this demonstration, students will observe two situations. First a student will be lifted off the desk as other students blow air into straws connected to a garbage bag in order to inflate it. Secondly, the class will observe a garbage bag shrink wrapping a student as a vacuum removes air from the bag.

Lab: Mega Marshmallows

In this lab, students will investigate the Kinetic Molecular Theory and particle motion while experimenting with a marshmallow. Students will observe how an increase in kinetic energy will cause particles to increase in motion. This concept will be extended into a discussion about additional real world thermal expansion examples.
