Osmosis Lab

 This lab was actually pretty cool.  We started by Getting some dialysis tubing. After this i mixed a substance of corn syrup and water into a beaker. Then when i mixed it good i used a pipet to transfer the water from the beaker inter the dialysis tubing. After we tied off the ends of the bags with string.  When this was done we weighed it on the scale.

I weighed it and it came out to be .73 on this scale. When i finished this i filled a beaker full of distilled water and dropped the dialysis tube with the substance in it, into the beaker.  We left it over night to see what would happen. When i came into class the next morning the substance had expanded in the bag.

Then i weighed  the bag again and the substance weighed more that it did the day before. It weighed out to be 1.65 on the scale the second time. After this i concluded that the water from the beaker had gone into the bag to make a reaction with the corn syrup that would expand it. The water level had lowered in the beaker and the water from that went into the bag with the corn syrup in it.
