The Inside Will Turn Black

Dialysis tubing. Apparently a well known experiment in biology classes. I did it last night and mentioned it to a friend. Without me saying "dialysis" or "tubing" she knew what I had done. She's a high school science teacher, after all but still - I was impressed.

Pleasantly, I was also impressed with myself. The class has become boring. Very, very boring. The teacher is good and his jokes aren't all bad but the information we're learning right now is remarkably dry. Remarkably. It was interesting at first but I have no need to know how the sodium and postassium molecules get into the cell. I really don't. I get the point, I get the idea. But I can't take much more of learning about diffusion. I have officially ruled out ever becoming a biologist.

However, a couple weeks ago... I had gone to class and walked out feeling stupid. Really, really dumb. I know I mentioned it in an earlier blog. Last night, new feeling. I did not feel stupid, I did not feel dumb. My brain showed up and I explained the experiment and the answers to our questions to all the girls in my group. It was awesome. I had enough faith in my own brain that I didn't just copy their answers. While I still have not mastered the microscope (nor do I truly have any desire to), I did master something else last night. I mastered, if only for a few minutees, understanding dialysis tubing. And just as the iodine found it's way into the model cell, a little more confidence found it's way into me.
