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.

1. What science ideas did you learn?
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.
