This was like a debate because at the end of this project, we would be voting for an organelle to be president of cell land. My team decided to learn about the cell membrane. We had to make   posters  (the poster above is a poster that my group created)  with catchy phrases or hashtags, and a commercial video that explains why the organelle that your team chose is important. During all of the researching, we also have to post "smears" on   edmodo  that was about why another organelle should not be "president of cell land." The smears looked something like this: Lysosomes have the ability to cause apoptosis, which is when a cell kills itself. Lysosomes can’t even take care of themselves!

http://www.aboutthemcat.org/images/biology/animal-cell.png Summary: This week I learned that all of the cell organelles are important to the cell and that there is not only one organelle that is important. Each organelle does something good, but there is also always a negative side of each organelle. All of the organelles depend on each other to be able to do their job. In other words, one organelle would not be able to keep the body alive without the other organelle. Lets take a cell membrane, for example. The cell membrane depends on the endoplasmic reticulum to transport proteins for the cell. As another example, the cell membrane works with the cell wall to allow molecules and other substances to enter and leave the cell.  Each organelle has a job that it needs to do for the cell, and some other organelles to work. For example, the cell membranes job is to protect all of the organelles that are inside of the cell. Without the cell membrane, the other organelles wou

It also keeps all of the important fluids that the cell will need inside of the cell. The cell membrane also keeps the dirty things that could harm the cell outside.  People usually think that the cell wall is what keeps all of the parts in the cell, but that is not true. Cell walls are only in plants, and they let the plant grow high with enough support so they don't fall. The cell membrane is composed of something known as the phospholipid bilayer. The phospholipids have one head, wh

This is a picture of my cartoon (Click on the picture to enlarge) About The Project: In class, we were assigned to create a scientific method cartoon. This cartoon would show each step of the scientific method. It had to be hand-drawn, colored in, and as neat as you could possibly make it. Each step would have a caption that describes what is happening on each image. This is a project that we did as a scientific method refresher. Summary: This week in science we were making scientific method cartoons. I learned that there are many ways each step in the scientific method in performed. I looked around and everybody had different images for each step, though all of them made sense. These are the steps of the scientific method: Problem Research Hypothesis Observe or observation Experiment Analyze data or data analysis Communicate your results Conclusion Backward-Looking How much did you know about the  subject before we started? Before we started doing the

https://commons.wikimedia.org/wiki/File:Baking_soda_and_vinegar.jpg Summary: This week in science we learned about conducting an experiment. We asked a question, made a hypothesis, and then conducted the experiment. My groups question was " Does baking soda and vinegar explode more with dish soap or without dish soap?" From this, we made a hypothesis which was "If the amount of dish soap affects how much baking soda and vinegar explodes, then when we add dish soap, it will explode less. Asking a Question: First, we asked a question. Asking a question is the first step of the scientific method. When you have a question, it should start with does , as you can see from my example. If you start with if , then people with think that it is your hypothesis. Another example for a question is “Does a paper airplane fly better with writing on it, or without writing on it? Constructing a Hypothesis Next, we made our question into a hypothesis. To do
