Gas Laws

Students should be able to understand the relationship between pressure and volume and temperature and volume via graphical analysis

Intro or Regular

I used the web-based version of the Charles and Boyle's Law flash animation. Students collected data via a virtual syringe and pressure reader and used excel to graph the data points that were generated. They then developed generalizations about the behaviour of a gas uner certain conditions bya analyzing the graphs they produced in excel.

Provides visualization or animation, Increases graphing skills, Increases modeling skills, Provides access to remote instrumentation, Increases data collection & analysis skills, Provides a virtual lab

The strengths of the site is that students get accurate data each time which will allow students to draw the correct conclusions about the behavior of the gas.

The animation is easy to use and I think it is a good learning tool.

The weakness of the animation that the data points that the students generate through interacting with gas are fixed based on the mathematical formula that is generating the data, so it is an "ideal" sort of an experiment.
