Day 5: 9-10-2019:
Day five already, day three in the lab. Because I didn’t see my grandfather yesterday evening I saw him this morning. It was really nice to see him, even though I still had some stomach ache and head caches. We had breakfast all together and around 8.45 I went to the bus station I was right on time. This time I took the right bus, finally! Today I want to do everything right. I watched Full House on the largest train trip. I walked to the department, someone opened the door for me. I settled down, but Daphne soon picked me up for further experiments. We looked at the DNA from yesterday if they had grown so far. They did, but we wanted them to grow even more so we put them back in the “oven”. We looked at both the yakult and the samples of my choice. After that we started our new experiment with a banana. This was an experiment to show how to see the DNA on a larger scale. In the real experiment we have done the previous days, we couldn’t really observe something, because it was so small to vision, but this would show me what it would look like. I started stamping the banana to a stew. We made a solution, from warm water from 60 degrees which we had put in the 60 degrees oven. We used soap, because soap breaks down the cell and due to the break of the cell we can get to the DNA. The soap also breaks down the nucleus, in this way we really get to the DNA. We added ethanol and soap and some salt. We put this in the warm water, so nothing would cool down. We put the banana in the solution as well and we stirred this for around 15 minutes. Than we filtered it but that took quite some time, we put everything in the 60 degrees oven so it would work faster. But we first had lunch at half past 12. Around this time they introduced the winner of the nobel prize. The winner was Mr. Goodenough he won due to the invention of Lithium-ion batteries. We had lunch I had my selfmade sandwiches and we talked about movies and streaming and blue raid, random but fun! After lunch, we went back to our banana DNA. It was completely filtered. We added the ice cold Ethanol to the solution, this would make the DNA stick to one side, since the ethanol is ice cold and the solution was really warm. We had to pipet the DNA out of the tube and put that on a plate. It was really cool to see the DNA visible like that. I took some nice photos of it because tomorrow they would look different. After the banana part we made some new samples for tomorrow. We were going to look at those samples under the microscope. We warmed our LB solution in the microwave and I poured those into the plates. We waited for some time because it had to become solid. In the meantime, we made some new tubes with the DNA to try it again for tomorrow, we put those in the fridge. Daphne told me we were going to do something with ice this week, which would have a cool effect! Later this day I will go to the museum of the University. The museum consists of all kinds of animals! Daphne and I walked to the museum together, Felix would wait for her at the tunnelbana. The museum seemed really big from the outside and spectacular. I was a bit anxious I had to pay my entrance, but if if that was the case I would have paid for it because it seemed like it was worthy. But I didn’t need to pay a penny, it was completely free. I went to the first area and Daphne went back to the tunnelbana. It was cool and interesting to see all those animals there. I took so many photos and sent many snaps to the squad goals. I believe I spent around 1.5 hour in the museum. There were many games to play, like how far I could jump, my balance etc. There were so many different areas from micro to enormous. Around 16.45 I left the building took some last photos, took some maps and booklets. I took some photos outside as well and then ate my last piece of my bread and walked to the tunnelbana. This time I found everything easily and correctly, I listened to music and watched Full house again. What I just came to realise was that the train station stops at Akala and that looked just like Tensta. I took the bus the other bus I could have taken just left so I waited five minutes. In the bus I listened to music and than walked home and later phoned the AH for a problem which was solved. Babou was home and I changed and ate dinner, rice and chicken. After that I started cleaning the bed which I had made a mess of because of my bleeding nose. I took some time, but it still wasn’t completely clean, but better. I did the dishes, took a shower, threw the bin out and cleaned everything. Did some homework and than at 21.45 my uncle came home from work. Tomorrow is his birthday which is fun too, he isn’t going to celebrate, what even funnier was that my grandfather didn’t even know it is his birthday tomorrow!
