CER-Dialysis Tube Diffusion Lab
	2 pts	4 pts	6 pts	8 pts
Diffusion - possible 4 pts.	2 Partially explained that diffusion was occurring with an explanation of high to low concentrations	4 Clearly explained that diffusion was occurring with an explanation of high to low concentrations.	6	8
Sugar Jar - possible 8 pts.	2 Does not explain that Sugar moved from tube to outside the jar as evident from the glucose test strip color change. Does not explain that osmosis/ diffusion of the water into the tube caused it to swell. Indicated H to Low concentrations	4 Partially explained that Sugar moved from tube to outside the jar as evident from the glucose test strip color change. Partially explained that osmosis/ diffusion of the water into the tube caused it to swell.
