Diffusion
Explore the motion of particles as they bounce around from one side of a room to the other through an adjustable gap or partition. The mass of the particles can be adjusted, as well as the temperature of the room and the initial number of particles. In a real-world context, this can be used to learn about how odors travel, fluids move through gaps, the thermodynamics of gases, and statistical probability.

How can I set up a controlled experiment to test how one variable can affect diffusion?
I revised activity B to reflect the AIM and the Do Now. I incorporated 2 Regents questions for the Do No... (more)w. Activity B is a great revisit and practice for Experimental design.

How does temperature affect diffusion?
In my school we use Aims and Do nows therefore I revised the worksheet to reflect that. I only needed to ... (more)do activity A with my students, which is why I chose the title (AIM) above.
