Blog #2: For Second Marking Period

Well this week went by really fast. I was happy that it went back quickly; I really can’t wait until tomorrow. It will be Saturday and I can get some sleep, before getting started on some more work. Well, anyway, today we did an experiment designed to show use the effects of Cellular Respiration. My partners and I started our experiment today. We had these germinated and non-germinated beans, and some beads that we placed into small containers. Then we put a cork on the cover and pored some food coloring into the glass tubing. The question that we tried to answer was, “How does increasing the temperature affect the pressure and the volume of the gas?” My group made some predictions about what would happen in the experiment. We said, “As the temperature increases, the pressure of the gas increases too. The volume will decrease because it allows molecules to vibrate faster, which makes them move at a higher speed.I am looking forward to next week and I hope that I can fix my data charts. See you Monday!!  

Blog #1: For Second Marking Period

Okay, so this is the second marking period. I have to do more blogs and I guess that this will happen be happening all year. So this week was really interesting, we did a few experiments this week that have talked a lot about Osmosis and Diffusion.  We did this experiment that we looked at the way an onion cell looks like under a miroscope. The cells in the onion were all spread out. But, then we put NaCl on the onion this made the cells shrink, they became close together and not so spread out. This lab allowed us to see the effects of osmosis. Another lab that we did was dealing with a few different molars of water. Then we used some tubing to hold the Glucose/Starch solution. Then we placed the tubing into the solutions of water. Over time the water turned an Amber color leaving the solution in the tubing a dark blue/purple color. This reaction made it clear that thought the process of diffusion, the glucose/starch solution transported itself to the water solution that surrounded it. I think that the classes were really cool and they were easier to fallow. I like it when we are given a written out lab. I think that it saves a lot of time. It also allows people to keep all of their notes in one place.

So... today I went to see about my grade in class. I now realize that I should go and ask much sooner than the day before the end of the marking period. I will make a mental note of that. So I found out that I am not doing as well as I would have wanted to. I want to do well in this class I mean I really do, but class is really hard and on top of all of that I have like 4 other AP classes. I wont fail the marking period that is for sure, but lets just say I could do better. AND I WILL!! I just have to work harder. I know that it is only going to get harder and I think that the best thing for me to do would be to drop the class. I still will take Biology, but Regents. I haven't really decided yet. I will have to think about this for a while. I dont know what to do! <3

I think that I have underestimated this class. I really had no idea what I was getting into when I was placed in this class. I mean I thought that it was going to be a lot of fun, and I thought that I was going to do well in the course. I mean when I look back on the science classes that I have taken in the past; I always thought that when it came to science dealing with the environment and animals, I was good at it. I really like the kind of science that has things to do with the environment. I want to do better!!!!! <3

Blog #4

Okay so I am not going to lie. I have been feeling a little overwhelmed with the amount of work that is needed for this class. I haven't really been doing so well with keeping the pace of the class, I feel like I am falling far behind.

Blog #3

How do I describe this week? Well I can start by saying that the cockroaches are still alive, that is a good thing. The only problem that my team seems to be having is that they tend to be frozen,whenever we take then down from their place in the classroom. The way that we have been dealing with this problem is by placing them under a lamp for about most of the class time. Their food seems to be decreasing,so what we will have to do on Monday is to give them more bread and maybe a few apples.
I must say, I have really enjoyed the labs that we have been doing in class. I find the labs in Biology to be a lot easier than the ones we did in Chemistry last year. Actually, I rather enjoy doing them and
they don't take as much time as the other ones.
So far, I have been doing okay with getting the work done within the class, but I haven't been doing so well with the readings. I haven't read my book for while and I have to get back to doing that. After all, I don't want to fall that far behind in my studies. Well... thats all she wrote.

Blog #2-Reflection

So I have been in AP Biology for a couple of classes now and I really enjoy it. I have had the opportunity to do many things. I have learned a lot about the elements of life and how all living things are connected. I have also been able to take part in a couple of experiments. I like the labs because they are not overly complex and although I have to think, I don't have to do many calculations. I really liked the experiment dealing with the cockroaches. I happened to name all of them, we have four in our tank and they all have names. Petey is the largest one, Phebe and Suzie are the twins and johnny is the smallest one. We have been keeping an eye on them for the last couple of days and I am so happy that they have not died yet. The hard part about the lab is keeping them moving. My group and I put the roaches in the darkest place in the class and it tends to get kind of cold. So, at the begining of every class we take a lamp and heat up the cage for about 5 to 10 minutes. That way they can warm up; I don't know if roaches are warm or cold blooded, but either way they tend to move more when the light is on. It also seems like they only enjoy fresh food, they haven't been eating the bread that was left in the tank.
I wonder... if we were to change the conditions of the tank to something warmer will that help the roaches? Well that is something to consider.
