Classroom Resources: Gases
51 – 62 of 62 Classroom Resources
Observations, Density, Chemical Change, Density, Inferences | Middle School, High School
In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candles to extinguish in order of height. Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.
Chemical Change, Gas Laws, Pressure, Acid & Base Theories, Indicators, Solubility Rules | Middle School
In this lesson, students will determine the pH of several liquids with litmus paper or a pH probe. Next, students will explore how pH affects the production of gas with Pop Rocks. Students will also investigate how Charles’ Law affects Pop Rocks. Finally, students will design their own experiment with Pop Rocks.
Physical Properties, Gas Laws, Pressure, Ideal Gas, Volume, Graphing, Error Analysis | High School
In this lab, students stack books on top of a closed syringe and use the volume change to determine the mass of the books.
Temperature, Gas Laws, Pressure, Volume | Middle School, High School
In this demo, students will witness the relationship between temperature and volume as well as temperature and pressure.
Pressure, Conservation of Matter | Elementary School
In this lab, students will conduct a chemical reaction that will be used to launch a rocket.
Gas Laws, Balancing Equations, Stoichiometry, Mole Concept, Chemical Change, Dimensional Analysis, Volume | High School
In this lab, students make real-world connections of stoichiometry with the design of car air bags.
Observations, Density, Temperature, Gas Laws, Density, Pressure, Physical Change, Identifying an Unknown, Molar Mass, Ideal Gas, Volume, Error Analysis | High School
In this lab, students will use gas laws to calculate the molar mass of dry ice and then use the information to identify the compound that makes up this substance.
Temperature, Gas Laws, Pressure, Volume | High School
In this activity, students will use models to predict behaviors of gas. They will conceptually and quantitatively solve problems, but the emphasis is put on the conceptual changes through modeling exercises.
Temperature, Gas Laws, Pressure, Interdisciplinary, Stoichiometry, Ideal Gas, Volume | High School
In this lesson students will learn about the mechanisms and properties of airbags, and examine the choice of airbag inflator from several points of view.
Temperature, Gas Laws, Pressure, Volume | High School, Middle School, Elementary School
In this demonstration, students will observe the impact of temperature change on a gas through an engaging demonstration using simple household materials.
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.
Density, Physical Properties, Temperature, Gas Laws, Density, Pressure, Molecular Motion, Ideal Gas, Volume
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.
