1 – 16 of 16 Classroom Resources

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.
Density, Temperature, Density, Molecular Motion | Elementary School

Lab: Observing Density of Gases and Liquids

Students will learn about and discuss the behavior of a gas using examples of convection and an optional teacher-led demonstration. Students will then participation in a lab where they will investigate water currents by observing the results of mixing colored warm water with room temperature water. The lab will be followed by a discussion about the molecular activity of the water mixture.
Density, Chemical Change, Density, Combustion, Chemical Change, Kinetic Molecular Theory | High School

Demonstration: Liquid and Gas Burning Comparison

In this demo, students will witness the burning of a substance in its gas and in its liquid states. They will carry out the demonstrations themselves, and compare the results of the two reactions.
Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Middle School, Elementary School

Demonstration: Investigating Gas Density

In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. 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 candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.
Density, Temperature, Sublimation, Gas Laws, Density, Pressure, Phase Changes, Interdisciplinary, Physical Change, Mole Concept, Dimensional Analysis, Measurements, Ideal Gas, Volume | High School

Demonstration: Ideal Gas Law using Carbon Dioxide

In this demonstration, students observe dry ice sublime while the CO2 gas fills a balloon. They then calculate the moles and volume of CO2 produced.
Density, Temperature, Chemical Change, Gas Laws, Density, Pressure, Balancing Equations, Stoichiometry, Chemical Change, Dimensional Analysis, Kinetic Molecular Theory, Ideal Gas, Volume, Graphing | High School

Lesson Plan: The Gas Laws Unit Plan

The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach the Gas Laws to your students.
Density, Temperature, Gas Laws, Density, Pressure, Kinetic Molecular Theory, Ideal Gas, Scientific Method, Volume, Experimental Design | Middle School, High School

Activity: Hot Air Balloon

In this activity, students use their knowledge of Charles’ law to build a hot air balloon and evaluate its design.
Temperature, Gas Laws, Density, Pressure, Volume | High School

Lesson Plan: Gases Unit Plan

In this lesson, students will investigate gases similar to how scientists learned about them “back in the day.” Students begin by investigating gas behavior, then they investigate gas density and use this to interpret Avogadro’s hypothesis that gases under the same conditions combine in simple whole number ratios.
Density, Temperature, Density, Pressure, Measurements, Volume, Error Analysis, Error Analysis | High School

Lab: Gas Density and Relative Molecular Mass

In this lab, students will quantitatively determine the densities of four gases.
Density, Chemical Change, Density, Chemical Change | High School, Middle School, Elementary School

Demonstration: Fire Extinguisher

In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.
Observations, Density, Density, Inferences | Middle School, High School

Demonstration: Qualitative Look at Gas Density

In this demo, students witness three types of gases and observe their relative densities to air.
Observations, Density, Temperature, Gas Laws, Density, Pressure, Measurements, Matter, Volume, Graphing | Middle School, High School

Lab: Pressure Bottle

In this lab, students determine the relationship between volume and pressure of a gas and its temperature and address the common misconception that air does not have mass or density.
Density, Molecular Motion, Kinetic Molecular Theory, Entropy, Intermolecular Forces, Volume | High School

Activity: Connecting States to Entropy

In this activity, students use blocks to model different states of matter and the Kinetic Molecular Theory to understand the concept of entropy. This is a concept mandated by SAT level or AP level high school chemistry class.
Observations, Density, Chemical Change, Density, Inferences | Middle School, High School

Demonstration: Comparing Gas Density

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.
Observations, Density, Temperature, Gas Laws, Density, Pressure, Physical Change, Identifying an Unknown, Molar Mass, Ideal Gas, Volume, Error Analysis | High School

Lab: Molar Mass of Dry Ice

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.
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.
