1. This week we learned about the process of protien synthesis. We also learned about the organelles again. We all made analogies comparing a cell and something that we thought was like a cell in some sort of way. I learned that the process of protien synthesis goes like this..
First the DNA gets a message. The mRNA then gives that message to the rbosomes. The ribosomes solve that message and tell the amino acids what they have to do. They DNA unzips and the amino acids match up with a base. Three bases put together form a codon. Finally, the codon makes RNA.
2. I learned about the process of protein synthesis by playing this game in class. Different students acted as different organelles and we acted out the process of protiensynthesis. I think participating in this game really helped me learn about proteinsynthesis. I learned about the organelles by making an analogy. I think that this helped me learn about them because I really had to think about the organelles and their functions to make a correct analogy.
3. This is important to know because it will really help me be more prepared for the test on Monday. It is also important to know about these things because they will help me in future scientific investigations because i will be able to identify protiensynthesis and also identify the different types of organelles.

Blog 12-The steps of photosynthesis
First, a message is sent to the cell to see how much protien it needs to make. The DNA starts to come undone so there is only a gene that has to do with that protien. The nucleotides match up with on sugar backbone to make mRNA. A matches up with U and C matches up with G. Many copies of RNA are made and they leave the nucleus and enter the cytoplasm. The RNA comes together with a ribosome and the ribosome reads the message that the RNA had. There are codons and they have to be read. When that is finished the right amino acids are activated by an enzyme. Then the amino acids attaches to the correct tRNA, or a transfer RNA. Then that tRNA goes and conects to the next one and so on! That happens until everything is read and it forms a polypeptide chain. The polypeptide folds as it's final transformation. Multiple copies of protien are made in this process. The mRNA is recycled so it can be used in different transformations.

1.What science ideas did you learn?
This week i learned about photosynthesis and respiration. We learned how to make the equations even. We also learned about fermantation and how that is respiration without oxygen. We learned that fermantation gives of alcohal instead of CO2. We also learned about DNA. We actually got to see real DNA from James' spit! We talked about how the DNA could be so big when the cell that it's in is microscopic.
2.How did you learn these ideas?
We learned about these ideas by doing research. We learned abotu respiration by doing experiments and having class disscusions to see what everyone thought. We learned about photosynthesis the same. We learned about fremantation because half of the class did an experiment that involved a balloon on a vial and we were going to see if the balloon grew, it did. We learned about DNA by doing this experiment where someone swooshes water in their mouths to collect DNA and then we added some other liquids to it. This helped us see the DNA and we could actually see what it looked like.
3.How might these ideas be helpful?
These ideas will be helpful because now that we are more educated on respiration, photosynthesis, and DNA, we can come to better conclusions about what we observe. If we see white and stringy stuff we will know that there is a possibiliy that it is DNA. If we see condensation on something we will know that something has to be respirating. Finally, if we see something moving that means it needs photosynethesis into energy.

1. What science ideas did you learn?
This week i learned about respiration and photsynthesis. I learned the repiration process has to even out the amounts of carbon dioxide, oxygen, and hydrogen. I learned that we dont breathe out oxygen, but we do breathe out carbon. We breathe in water and oxygen.
2.How did you learn these ideas?
I learned these ideas by making flow charts. We made a flow chart for respiration and photosynthesis. We researched a little bit about photosynthesis and respiration, but not that much. We learned about making the amounts of gases in respiration equal by doing this experiment with chairs and trees. We learned about breathing in water and oxygen by having class disscusions. We learned abou t breathing out carbon and not oxygen by doing an experiment.
3. How is this idea helpful?
These ideas are helpful because now that we know more about photosynthesis and respiration, we can make better conclusions, hypothesis, and predictions. It is helpful to know about having equal amounts of the gases and everything because we can understand respiration much better.

1. What science ideas did you learn?
The science ideas I learned this week are plant and animal cells. We learned about the organelles in them and we also learned about paramecium. We also learned about paramecium and how they move. We also saw a real paramecium with a microscope.
2. How did you learn these ideas?
I learned these ideas by doing experiments with the paramecium and also by researching. We also looked at diagrams to learn about the animal and plant cells and what organelles were in them. Our class also made a diagram for a plant cell, animal cell, and bacteria cell.
3. Why is it important to learn these ideas?
It is important to learn these ideas because if we see a cell in a microscope it would be really helpful to know if it was a plant cell, animal cell, or bacteria cell. It is helpful to know about paramecium and how they move because if we see something like that in a microscope we can identify that it is a paramecium.

1. What science ideas did you learn?
This week I learned about plant cells and animal cells. I learned the names of all the organelles in these cells and what they look like. I also learned the function of these cells. We also learned what a paramecium was. We confirmed that it was in the group of an animal cell. I learned that paramecium has cilia on the outside of it and that's what makes it move.
2. How did you learn these ideas?
I learned these ideas by doing a lot of research for homework. We were assigned to look up what plat and animal cells were and what the organelles in them were called. We learned about paramecium by researching and today we looked at lake water from Lake Suprise and through the microscopes we saw actual paramecium. I thought it was really cool to see an actual paramecium cell and to be able to see it move. We also saw it eat on leaves that were also contained in the microscope. I think being able to actually see the real paramecium in ation helped me understand it a little more. We learned the plant and animal cells by going up to the smartboard and labeling the organelles.
3. Why is it important to know these ideas?
It is important to know these ideas because it will help us in future experiments. Also today we took a quiz on the plant and animal cells and it helped to know which organelles were which. It is important to know about paramecium because even though it is only one example of an animal cell, it helps us understand animal cells a little bit more when we see an animal cell in real life.

I learned all the different parts of the plant and animal cells and that they share some of the same parts such as the nucleus. We also learned about what types of cells were contained in on the inside of our cheeks.
2.How did you learn these ideas?
I learned these ideas by doing experiments. For the potato and grass experiments we put potato and water under a microscope,potato and metholine,potato and lugol, and grass. We then looked and saw the differernt cells. The metholine and the lugol helped us see the different cells. We learned about plant and animal cells by going up to the smart board and labeling a plant cell and an animal cell. We learned what cells are on the inside of our cheeks by rubbing a toothpick on our inside part of our cheek and then rubbing it on a slide and then observing it under a microscope.
3.Why is it important to know these ideas?
It is important to know these ideas because it is helpful to see what metholine and lugol do to help you see different cells. It is important to know about the different parts of plants and animal cells because you can compare it with other cells and if you didn't knwo the names of the parts and you thought that you discovered something about that cell, you wouldn't be able to ask a classmate what they thought it was because you wouldn't understand each other. It is important to know about cheek cells because again it could help us with the experiments we have to do because we might see the same thing in one experiment that we saw in the cheek cell experiment.

1. What science ideas did you learn?
I learned about the different types of bacteria. There is bocillus, cocci, and spirillum which are the shapes and diplo, tetra, strepto, and staphylo which are the groups. I also learned what bacteria could be in the pond water. I learned that campylobacter or salmonella can be found in our pound water samples. I also discovered that we could have different types of algae in our sample which is not harmful.
2. How did you learn these ideas?
I learnd these ideas because for homework we had to research what organisms we thught were in our pond water sample. I researched online and found the answers and made new predictions and hypthesies with the new data. I learned about the different types of bacteria by doing a wrkshet that we had for homework.
3. Why is it important to know this idea?
It is important to know this idea because when we are doing experiments with our samples, it is imnportant to know the different types of bacteria and if they are harmful or not. If we didn't know if they were harmful our predictions and hypothesies will be wrong. It is important to know what organisms are in the pond water because we can learn more about the water if we know the exact organism and what it does. It is also important to know the names of the organisms so fellow students can understand us when we are talking about our finds.

I learned the actual size of organisms and how we can barley see bacteria even with a microscope. I also learned that we might find paramecium in the pond water because that is pound in freshwater poundwater. I learned the definitions of words I did not know such as anoeba proteus. This week I also learned the parts of a microscope so i could pass the microscope quiz. From our test results I learned that the chicken from the Cheap Chicken Hut had a lot of bacteria colonies and the blade of the knife didn't. The pond water had a lot of living organisms.
2. How did you learn these ideas?
I learned these ideas by looking at the simulation to find the actual size of organsims. I learned about organisms in the pond water by researching what I found under the microscope online. I also looked online for the definitions I did not know that were included in the survey. I learnde about the test results by observing the results in the peitree dish and under the micrscope.
3. Why is it important to learn these ideas?
It is important to learn these ideas because by knowing more on what you discovered in your test results you can come to better conclusions. If you didn't know anything sbout the size of bacteria, your conclusion might sound like this, "in my results for the pond water i saw a lot of bacteria under the microscope" and that's incorrect.

1. What science ideas did you learn?
This week I learned about the structures of bacteria and virises. We think that bacteria is living while virises aren't. We think bacteria is living because bacteria is made up of cells which is a characteristic of life. Bacteria also has DNA, which is another characteristic of life. We think that virises aren't living because they aren't able to reproduce. Also, they don't have any ribosomes so they don't have any energy organelles. Finally, virses aren't composed of cells.
2.How did you learn these ideas?
I learned these ideas by studying pictures of the structures of both a viris and bacteria. I looked at the labels of both and realized that the viris didn't have all the characteristics of life and the bacteria did. I also learned these ideas by having class discussions and hearing different people's thoughts and predictions.
3.Why is it important to know this idea?
It is important to know these ideas because it will help us with the experiments we do. For the experiments that we are making up, we have to know a lot about bacteria and viris because we have to be able to tell if something has bacteria or if it has a viris. We also have to know if the bacteria and virises are alive to be able to make an accurate hypothesis.

1. What science ideas did you learn?
I learned about peitree dishes and how to use them. I also learned about macroscopic, microscopic, and sub-microscobic. Macroscopic is something that is too big to see under a microscope, microscopic is something that can be seen under a microscope, and sub-microscopic is something that is too small to see under a microscope. I learned how small cellsand organisms can be. I also learned that you have to be very careful while collecting a swab because if you press you too hard, you could get big clumps and ruin the end results.
2. How did you learn these ideas?
I learned these ideas by making hypotheses and looking at the simulation that was assigned for homework. This simulation helped me because it showed the the scale of cells and organisms. I never knew they were that small. When our class went into the bathrooms to collect data, I learned how to collect the data in a certain way.
3. Why is it important to know this idea?
It is important to learn these ideas because they help us collect and understand data better. For example, if I didn't learn how small the cells and organisms were, I wouldn't be able to understand the macroscopic, microscopic, and sub-microscopic.

This week i learned that we observe and make hypothesis and predictions in everyday life. We learned more about how the disease in the other schools and got some more information. We observed the absency chart and tried to find some patterns. Mr Segen was able to get the class results of interview tables and the calender of school events. These two thinga will help us because we can see if there are any suspicious happenings such as maybe raw meat at a school dinner which we would find on the calender.
2. How did you learn these ideas?
I learned these ideas by listening to other peoples questions and the answers. I also took notes and observed our experiments. I listened in the class disscusions and made sure that I understood everything. I also learned these ideas by observing the data that was on the website for the absencey table of the schools and the illness that was spreading very quickly.
3.Why is it important to know this idea (What real world applacation is there)?
It is important to know this idea because it will help you in real life. We make predictions and hypothesies everyday. For example, if the you think a friend is mad at you, you would automatically make a hypothesis to see if you did anything wrong. In the real world, medical researchers make hypothesis and prediction to see if the new medicine would work.

What I Learned This Week
This week I learned a lot of new things about science. I learned about HD statements and independent/dependent variables. We also did an experiment where we all had a test tube and a pipet. We then traded liquid with other classmates. When we were finished Mr. Finley put a chemical into our test tubes and if it turned red, that means you were infected by the disease, but if it turned green, you weren't infected. We also learned how to make a web to determine who started with the disease. We also answered some questions for homework about diseases and the causes of them and how they spread. Finally, I learned about living and non-living things. We discussed the characteristics of livng organsisms. We also made a list of ten living and ten non-living things.
