Compare how much X-rays get through two slabs of material of the same thickness by changing material properties (density, effective atomic number) and X-Ray source properties (energy, exposure(mAs)).

Control the spectrum of a diagnostic X-Ray source by changing energy (kVp), adding filtration to the X-Ray beam, and including ripple in the high voltage supply.

Explore X-Ray imaging. X-Ray control parameters include kVp (max photon energy), mAs (exposure) SID (distance to image receptor), added filtration, and ripple. The sample consists of two cylinders (identical size) embedded in a slab where the materials and sizes can be slected.

The Lotkaâ€“Volterra Predator prey model describes the population dynamics of a group of predators and their prey.

This model can be thought of a a tetherball where the rope does not wrap up around the pole. The simulation is used for a mechanics lab activity (video analysis) involving a softball swinging around the top of a 2 meter vertical pole with between 1 and 2.5 m of string.
