After you finished the procedure, and weigh your potato core you will find that the the potato core sunk at same rate. The salt water solution stayed at a constant weight. My potato core weight decreased in a small size. My hypothesis was proven correct.
If I put the potato core in the salt water solution then the core will decrease in size or weight.
1) Pour about 40 ml of salt water solution in a beaker or two. Which ever you prefer.
2) Cut out ´potato core pieces about the same length.
3)Using electronic balance, measure each o your potato cores separately. Record in data table. Then weigh the beakers beakers on scale and measure. Record your data.
4)Place potato cores in the salt water solution and let it sit for approximetly 20 minutes or longer.
5) Remove core from the solution and measure the mass of core. After, measure the beaker separately. Record data.
This activity was all about water and how it can move through cell membrane/cell walls. If there is a greater concentration of solutes inside the cell than outside the cell and the chemicals can not move, then water will start moving into the cell. If one area has a great deal of water, it has a high water potential. If an area has a great deal of dissolved material (less water) it has a low water potential. Water will attempt to move down it gradient, from high to low water potential. In this experiment you will observe this using potato cores that are placed into a solution of salt solution.depending on the water potential of the cells vs. the solution water will move in or out. This lab lets you observe this.
