1 – 15 of 15 Classroom Resources

• Density, Combustion, Lab Safety | High School

### Access is an AACT member benefit. 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.

• Combustion, Chemical Change, Chemical Change, Density, Kinetic Molecular Theory, Density | High School

### Access is an AACT member benefit. 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.

• Gas Laws, Sublimation, Ideal Gas, Volume, Temperature, Pressure, Density, Phase Changes, Interdisciplinary, Density, Physical Change, Mole Concept, Dimensional Analysis, Measurements | High School

### Access is an AACT member benefit. 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.

• Gas Laws, Ideal Gas, Volume, Temperature, Pressure, Kinetic Molecular Theory, Density, Graphing, Density, Chemical Change, Stoichiometry, Balancing Equations, Chemical Change, Dimensional Analysis | 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.

• Gas Laws, Kinetic Molecular Theory, Ideal Gas, Temperature, Volume, Pressure, Density, Density, Experimental Design, Scientific Method | High School, Middle School

### Access is an AACT member benefit. Activity: Hot Air Balloon

In this activity, students use their knowledge of Charles’ law to build a hot air balloon and evaluate its design.

• Gas Laws, Density, Temperature, Pressure, Volume | High School

### Access is an AACT member benefit. 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, Pressure, Temperature, Volume, Density, Error Analysis, Error Analysis, Measurements | High School

### Access is an AACT member benefit. Lab: Gas Density and Relative Molecular Mass

In this lab, students will quantitatively determine the densities of four gases.

• Chemical Change, Density, Chemical Change, Density | Elementary School, Middle School, High 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.

• Density, Density, Observations, Inferences | High School, Middle School

### Access is an AACT member benefit. Demonstration: Qualitative Look at Gas Density

In this demo, students witness three types of gases and observe their relative densities to air.

• Gas Laws, Matter, Density, Density, Temperature, Pressure, Volume, Graphing, Observations, Measurements | High School, Middle School

### Access is an AACT member benefit. 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.

• Entropy, Kinetic Molecular Theory, Molecular Motion, Intermolecular Forces, Density, 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.

• Density, Density, Chemical Change, Observations, Inferences | High School, Middle School

### Access is an AACT member benefit. 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.

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

### Access is an AACT member benefit. 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.

• Chemical Change, Combustion, Balancing Equations, Density, Specific Heat | High School

### Access is an AACT member benefit. Demonstration: Methane Bubble (Dragon Ball Z)

In this demonstration, students will observe the combustion of a methane bubble. This exciting demonstration can be used as a dramatic and engaging introduction to the concepts of combustion reactions, chemical change, and balancing equations.

• Molecular Motion, Density, Physical Properties, Density, Gas Laws, Ideal Gas, Temperature, Pressure, Volume | Middle School, High School

### 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.
