diff cc  







In this first simulation, learners experience the diffusion of a dye particle through other water particles. 

Learners can be guided to explain how diffusion occurs through a series of continuous random motion.


effects of TMr

In this second simulation, the effects of molar mass and temperature can be used as an exploratory activity for learners to conclude the effects that these have on the rate of diffusion.



Simulation of (1) diffusion and (2) effects of molar mass and temperature onm diffusion.

Sample Learning Goals

Inquiry-based Learning activity for students to experiment on diffusion, manipulating temperature and molar mass.
