Today during the lab I learned that when you put starch with iodine it turns the startch purple. I also learned that if the baggie is a little bit open substance can easily enter the baggie. Even with the tiniest open, substance can easily enter and leave the baggie. I noticed that there was high concentration because I saw tiny purple dots on the baggie.The plastic bag from the experiment acts like the cell membrane, letting in substances that fit in and not letting in other substances that do not.
I hope we do more lab experiments in the future!
Thank you Ms.Rousseau
Hey Josh. Nice explaining. That lab was one of many that we are going to be doing. Hope that they are fun
