This simulation allows the user to choose one of four substances (A, Ne, O2, H2O), vary the temperature of the container and observe the behavior of the particles of the substance providing a straightforward means to observe the relationship specified in the performance expectation and disciplinary core idea.
Be sure to use the simulation labeled “Basics.” There are two tabs at the top of the simulation. Use only “solids, liquids, and gases.” Note: the temperature can be recorded in K or C. by clicking on the “teacher” tab.
By scrolling down on the opening page of the simulation, one can find a number of lessons at various educational levels designed by contributors. This review is for the simulation but teachers may find the lesson,”Heat it Up!”, http://phet.colorado.edu/en/contributions/view/3814 more adaptable than the others. It can be modified to make it appropriate for this Performance Expectation and disciplinary core idea by eliminating question #2 and Kinetic Molecular Theory from the Introduction. The Going Further activity should be omitted since it involves pressure, which is not included in the DCI.
