Learners create a piston/cylinder assembly using SolidWorks. In this technology lesson, students calculate volume, pressure and Boyle's law constant. They simulate equalizing air pressure by moving the piston out of the cylinder.

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...
