Downloadable simulation showing inertia in action. A simple demo, but it nails the point home. This Demonstration depicts a simple experiment, in which a small car with an object on top hits an obstacle, and the object continues its motion in the same direction and with the same speed

Downloadable simulation: Periodic table in 3D (Mathematica)

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 game: Build the periodic table (Mathematica)

Downloadable game that lets you drill on the periodic table, position of the elements, and the types of elements. To put an element of the periodic table into the right place, first click a numbered box and then click the element. To remove an element from the table, click it again (hint: colors can be useful)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: Quadratic practice (Mathematica)

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: Spinning out sine and cosine (Mathematica)

Downloadable simulation of how the sine and cosine functions are made from rotation through a circle. Get a feel for how trig functions relate to coordinates and lengths. Imagine a point that starts at and rotates counterclockwise on the unit circle. If is the length (in radians) of the arc on the circle between and the point, then as the point moves around the circle its and coordinates are the cosine and sine of .

Downloadable simulation: Vector addition (Mathematica)

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.

Online simulation: Kinetic theory applied to Chemical reactions (PhET/UC Boulder)

Interactive simulation of what chemical reactions look like at the microscopic level. Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?
