What science ideas did you learn?
This week in science class we worked on the project to figure out what got all the kids sick, if it was the pond water or the chicken. We first practiced using a microscope and what the parts are called and do. We also practiced using a wet mount and a petri dish. Another thing we did was test chicken and pond water. We found that the chicken had a lot of bacteria and the pond water had some, but not as much as the chicken. We then decided to use the microscope and take a look at the pond water. We found things that were living and non- living, and we found out we can not see bacteria under a microscope.
How did we learn these ideas?
We learned these ideas in a couple of ways. One way was by taking a quiz to learn more about a microscope and the other was taking a quiz to practice using a wet mount. This helped us because if we wanted to use one of them, it was practice so we knew what we were doing. Another way we learned these ideas were from notes and class discussions.
Why is it important to learn these ideas?
It is important to know how to experiment using petri dishes, wet mounts, and microscope because if you want to test something and you need to use one, you will know how. Also knowing how and what the parts of a microscope do and are is important because if someone tells you to look through the eye piece or put something on the stage, you will be lost and have no idea what they are talking about. It is also important to know these ideas because if you are answering questions about your experiment, and you are not sure how to, then you could look at your experiment, and if you did everything good then you should be able to answer them correctly.

What science ideas did you learn?
This week in science class we learned about the structure and function of a cell. We learned that they have DNA, they are made up of cells, convert agar into energy, and need energy. We also learned that they are non-living. Another thing we did this week was work on our project, we had to write down what we wanted to test, to find more information on how they got sick. We could use a petri dish to experiment or we could use something else we learned this week, called a wet mount.
How did you learn these ideas?
One way we learned these ideas were from homework and class discussion. Learning about what a cell is and the structures was a homework assignment, but the next day we talked about it in class. We also wrote a list of the structure and function of a cell in class. For how to use a petri dish and a wet mount, Mr. Finley showed us in a group.
Why is it important to know this idea?
It is important to know how to use a petri dish and wet mount. Its important to know because if you are doing an experiment or would like to test something in the future for school and you need to know it could be helpful. Its also helpful right now because, to test things for our project we need to know.

What science ideas did you learn?
This week in science class we learned a little more about a project we work on last week. For this project we had to figure out why so many kids were out from school. This week we found out the restaurants they ate at and which ones they got sick at. Then we wrote our observations and made a hypothesis. We also learned what a petri dish was and how to use it. Another thing we did this week was learn about macroscopic, microscopic, and sub-microscopic and what they are.
How did you learn these ideas?
We learned these ideas in many different way. For the project, were we had to find out where the students got sick, we looked at the results and made a hypothesis. That gave us an idea were the student may have gotten sick. Also, to learn more about petri dishes, we went to the bathroom and got a swab. After that we rubbed the swab against something we thought had a lot of bacteria or, then something that didn't have so much bacteria. Then we divided the petri dish into two parts and rubbed the swab with the bacteria on one side of the petri dish and the swab with no bacteria on the other side. We learned then when rubbing the swab you must be very careful.
Why is it important to know this idea?
It is important to know these ideas because when we had to look at the results from the restaurants we practiced making an observation and hypothesis. Even knowing how to use a petri dish is important. It is important because if you want to test something else, you would need to know how to use one.
