In this lab activity, we tried to find out if osmosis works in other ways than cells. My hypothesis is that even though it seems like the packages are “waterproof” the material will still leak out. The procedure started by getting bags of starch and glucose and putting them in the water. We would then put iodine into the starch bag and wait twenty minutes. After the twenty minutes, we would look at the results and get a glucose chart and look at the glucose level in the water.

The picture on the left is the starch while the glucose is on the right.This picture shows the starch at the beginning when we poured the iodine in.

This is a picture of the glucose levels results.

This is after twenty minutes of having the iodine in the starch. This means the iodine leaked into the starch.

This picture shows the starch at the beginning when we poured the iodine in.

This picture is the iodine we used. We used 15 drops.

My hypothesis was proved because in the glucose container, the glucose leaked into the water, as shown by the picture above. In the starch container, the iodine leaked into the starch making a blue color. We did this lab to explain osmosis and the transmission of fluids and materials between cells and the environment. I learned that cells try to have an equal amount of X as the environment.
