Potato+Lab


 * Introduction**: Diffusion is the spreading of particles moving from places of higher concentration to lower concentration. Water can also move by facilitated diffusion, which means the particles are unable to go through the cell membrane therefore they need the help of the protein channels. In this lab we will find out if the sugar in the sucrose solution will change the weight of the potato cores. The sugar cannot move through the cell membrane, it would have to use the process of facilitated diffusion. The sugars might not be able to fit through the protein channels, so depending on the amount of sugar in the solution we are supposed to find out how much water can move through the protein channels.



**Evaluation/Reflection:** The things we did well in this lab was using our lab time wisely and working and being very precise in our measurements. We cut our potato slices EXACTLY the same and they even weighed the same. We found that since our cores initial weights were the same our hypothesis was more accurate whereas the other group’s initial mass was all-different therefore their graphs were not as accurate as ours. Some things we could have done better with are working together for sharing information. We could have waited for exactly 24 hours before taking our final weight. I’m not sure that this would matter because we took all of our potato cores out at the same time, and I think that was just the point.
