Examine the science behind rates of diffusion. The video lesson and following interactive activity focus on the molecular components of different smells. Learners monitor the diffusion of each smell as they 'race' through a room.

Gaps are essential to engineering bridges and roads. Learners watch a video showing a typical construction of a bridge to see why they're so important. They then manipulate an interactive to model the effects of temperature change on the...

In this chemistry worksheet, students study the structure of matter and the kinetic molecular theory using an interactive online website.

Salt is the go-to material when people need to melt ice—learn the chemistry behind its effectiveness with an interactive lesson. Pupils watch a short narrative and then explore the concept through a simulation. Young scientists...

Discusses the basic concepts of kinetic molecular theory and presents animations illustrating the behavior of molecules in a closed box. Requires Java.

A page containing an interactive JavaScript form which allows the visitor to investigate the relationship between various state variables. Visitors input values of a few variables and observe the effect upon the other variables. Options...

Adjust the temperature in this simulation to observe the effects to moving particles. Graphs can be created from collected data.

From the companion web site for the Contemporary College Physics textbook. An ideal gas law simulation in which the motion of individual particles inside a closed container is simulated. The number of particles, external pressure, and...

[Free Registration/Login Required] Learn about temperature and molecular motion and why they are important to consider when building a bridge.

A JavaScript calculator which allows one to investigate the distinction between an ideal gas and a real (Van der Waal or Dieterici) gas. State variables can be entered and an update on the values of other variables are given (as...
