Diffusion Across a Semipermeable Membrane
Semipermeable membranes allow water to go through—but not larger molecules. The simulation encourages pupils to adjust the membrane pore size to understand how this works. It also provides a way to trace the movement of a single molecule.

Diffusion of a Drop
Trying to learn through diffusion rather than simply studying the material rarely works for scholars. This simulation helps make learning diffusion fun. Pupils add a drop of dye to water and observe the diffusion as the molecules bounce...

Intermolecular Attractions and Boiling Point
Why do different substances have different boiling points? Through an interactive lesson, learners explore how intermolecular attractions affect boiling points. They interact with molecules through an animation and make conclusions about...

Filling the Pool
Fill your mind with math as you think about filling a pool. Given information about the rates of two pipes, one filling a pool and one draining a pool, learners determine a piecewise function that models the volume of water in the pool...

Three Rubber Bands
Stretch your mind about triangles. Given a triangle, scholars consider a smaller triangle formed when they stretch three rubber bands from each vertex to the opposite side. They determine the ratios of the areas and perimeters of the...

Molecular View of a Solid
Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.
