__** Problem: **__ What is a dialysis treatment? We don't know! But Grandma needs to know as she will have one soon. So our job is to research more about a dialysis treatment and use those facts to make a video that will inform Grandma.

-Research on the internet -Interviews with several educated adults
 * __ Solution: __**

Procedure: We filled four bags of dialysis tubing; two with 10 mL of distilled water, one with 10 mL of 15% sucrose, and the remaining one with 10 mL of 30% sucrose. After that we placed one of the distilled water tubing, the 15% sucrose, and 30% sucrose in beakers filled with distilled water. The other distilled water tubing was placed in 30% sucrose. We weighed them after certain time periods.
 * __ Osmosis Lab __**

Observation: The bags placed in distilled water beakers increased weight as time passed. The bag placed in the beaker full of 30% sucrose decreased weight rapidly as the time went on.

Conclusion: Those bags placed in the distilled water beakers increased weight because water cells were allowed to enter the bag. The bag placed in the 30% sucrose had sugar cells stopping most of the water cells from entering the bag, thus the weight decreased.
