Text Set: Gases (gas laws)

1) PhET Gas Properties simulation

 http://phet.colorado.edu/en/simulation/gas-properties

10-11 Grade Level

PhET is a website that offers many interactive simulations for use in science classrooms.  The simulation on gases allows students to manipulate the variables of pressure, temperature, and volume, and observe the changes in particle motion.  Students can also postulate on the relationships between the variables through analysis of the simulation.

2)  Railroad Tanker Implosion

No grade/reading level

This 19 second clip shows the implosion of a tanker car due to a vacuum effect that took place after workers steam cleaned the tanker, sealed it (with heat inside), and the temperature dropped over night. The video can be used as a hook to begin hypothesizing what forces were at work in the phenomena.

3)  Connected Chemistry:  Gas Laws

http://ccl.northwestern.edu/curriculum/ConnectedChemistry/CC_GasLawsTeacher.pdf

10+ Grade Level (teacher guide, so irrelevant)

This text outlines 13 activities (7 of which involve online simulation), which connect work with gases and gas laws to everyday objects, experiences of students, and natural phenomena.  This will be especially helpful in the planning of gas law curriculum.

4)  NetLego

10-11 Grade Level

http://ccl.northwestern.edu/netlogo/index.shtml

NetLego is another simulation site, which contains a "Modeling Commons" page.  This page is dedicated to simulations created by teachers and students.  There are 7 simulation (mentioned in text #3), which deal with temperature, pressure, and volume relationships, ideal gas laws, and air pressure.

5)  Gas Laws and Scuba Diving

11th Grade Reading Level

This article describes the relationship between Boyle's and Henry's Law to scuba diving survival.  It uses temperature, pressure, and volume and discusses them in the context of divers' gear.  The reading level may be a little high for a standard course, but would be acceptable in a higher level chemistry.

6) Gas Laws Comic Strip

7th grade reading level

7) Boyle's Law model

8th grade reading level

http://www.grc.nasa.gov/WWW/K-12/airplane/boyle.html

This page is provided by NASA and offers an explanation along with a simulator of Boyle's Law.  In a chemistry classroom, the engine demonstration placed next to a graph will allow students to visualize what the law explains.

8)  Charles's Law model

8th grade reading level

http://www.grc.nasa.gov/WWW/K-12/airplane/glussac.html

This page is provided by NASA and offers an explanation along with a simulator of Boyle's Law.  In a chemistry classroom, the engine demonstration placed next to a graph allows students to visualize the relationship between volume and temperature.

9)  Kinetic Theory Mind Map

8th grade reading level

https://hwb.wales.gov.uk/cms/hwbcontent/Shared%20Documents/VTC/2010-11/physics/kineticTheory/eng/Videos/Prezi_Mind_Map.mp4

This mind map is a Prezi that offers brainstorming on the kinetic theory and its parts.  It could be useful after students create their own graphic organizer or the class creates the organizer to expand on their knowledge and add to their thoughts.

10)  Boyle's Law Cartoon

6th grade reading level

http://www.teachnlearnchem.com/Boyles%20Law.htm

The cartoon demonstrates the relationship between pressure and volume in the context of an olympic competition.  This would act as a great memory aid following teaching of Boyle's law.

11)  Gas Law Comic

8th grade reading level

http://tie-dye-flag.deviantart.com/art/Chemistry-Comic-of-Gas-Laws-359036813

The comic describes the effects of Boyle's law after a scuba diver returns from a dive.  The diver is suffering from the "bends", which is a phenomena that can be explained by Boyle's law and the effects of volume and pressure on blood oxygen levels.

12)  Charles's Law Intro Comic

6th grade reading level

http://stripgenerator.com/strip/698727/chem-gas-laws-comic-1/

This comic strip uses the example of balloons shrinking with a drop in temperature to demonstrate the phenomena of Charles's Law.  This would be a good hook to have displayed at the beginning of class.

13)  Is Hell Exothermic?

10th grade reading level

http://www.nclark.net/GasLaws

I may not use this with my students, but it is an interesting read.  This reading describes the variables that would alter whether or not hell is exothermic or endothermic.  The answer was submitted by a college student and demonstrates higher order thinking that could inspire much discussion in a chemistry classroom.

14)  Gas Laws powerpoint

8th grade reading level

http://www.slideshare.net/lallen/gas-laws-1232856

The powerpoint details the gas laws and provides many images that would be useful for relating the gas laws to real-life phenomena.  There are example problems embedded within the powerpoint along with other diagrams that would be useful for practice and demonstration.

15)  Can Crushing Experiment

no reading level

http://www.youtube.com/watch?v=0NZmo-qQxIk

The can crushing experiment video can be used as an inquiry demonstration or as an in-class experiment for students.  The demonstration is a small scale demonstration of the tanker crushing and can be used to further students' understanding of the effects of temperature, volume, and pressure.
