Downloadable simulation showing periodic trends in the properties of elements in a novel way. Good for seeing how electronegativity, atomic radius, and so on, change across groups and periods. This Demonstration shows 3D bar charts of the periodic table with various element property values

Downloadable simulation: Annotated quadratic polynomial (Mathematica)

Downloadable simulation that lets you see how a second degree polynomial (aka, quadratic) changes shape when you change the coefficients. Get a good feel for how the graph changes. This Demonstration will also let you see where the zeros of the polynomial are. Good experience for constant acceleration problems. The zero is when a body in free fall, say, crosses the origin of your coordinate system.

Downloadable simulation that lets you get a feel for how a second degree polynomial (aka, quadratic) changes shape when you fiddle with its coefficients. Adjust the coefficients of the parabola to hit all of the dots. Then, click the button to get a new set of dots. Good for constant acceleration problems, since distance vs. time is a quadratic for this situation.

Downloadable simulation of how two vectors add using arrows and using components. This Demonstration illustrates head-to-toe addition of vectors in the coordinate plane. Initial and terminal ends of the vectors can be located in an [-8, 8] by [-8, 8] window.
