Cell Story
Part 1: Cell story
I am a colorless cell living in blood and body fluids of my host’s body. My name is Leukocyte, but other cells call me white cell. When my host has an infection, signals go to marrow and special glands to create more white blood cells. I was manufactured in red marrow of bones and my some of my friends were born in special glands elsewhere in the body. There is a white cell club where only the largest blood cells can enter. Their main duty is to protect their host from infectious diseases as a solider and maintain the immune function. In the white cell club, there are 6 types of leukocytes such as, lymphocytes, macrophage, neutrophil, eosinophil, and basophil. I belong to neutrophil sector. Our group, neutrophils, makes up the majority of total white cells. For instance, we have an outstanding popularity of 50% to 70% of white cells. Mature neutrophils like me are twice the size of red blood cells and has a segmented nucleus. My role is to ingest bacteria and invaders unfamiliar in the body. Moreover, I can squeeze through tiny blood vessels and leave bloodstream to enter other tissues that are being attacked by foreign invaders. I have worked in my host’s body for 18 days which means I got 2 more days left to finish my duty. Healthy person has 4 and 11 thousand leukocytes in every cubic inch of blood. When leukocytes count drops, my host will experience immune degradation. On the contrary, too much leukocytes count in the body will cause leukemia.
Part 2: The Making of Cell Story
I asked questions like what is the function of leukocyte? What is the life cycle of leukocyte? What types of leukocytes are there? What is the structure of leukocyte? What happens when leukocytes count drops? How many leukocytes does the healthy person carry? to create my own cell story. I used EBSCO Host, YouTube and google for my research tool. I started with the google to narrow down what I wanted to know about specifically. Then, I used EBSCO for academic research. To verify and cite the information I found, I checked if the website and author was credible. It was difficult to find the right article for function and structure of leukocyte in EBSCO and gale because it was irrelevant to what I was looking for and too professional. However, I still got some useful information about leukocyte. I think I could have done better by making my cell story more interesting.

This is my science inquiry project
Collaboration Fluency
Establish:
Group Members: Zeena, Jenny, Riley, and Myles
In order to succeed, you must fail.
- What skills and strengths do each of the group members have to help you accomplish this project? (mention names and skills)
Zeena- encouraging team members
Jenny- organizing and recording skills
Riley- finishing projects in deadline
Myles- calculating skills
- How are you going to divide up the workload? What roles and responsibilities are assigned for each person?
Zeena- Teamwork (encouraging and helping team to stay in task)
Jenny- reporter (interviewing racers and taking records of an event)
Riley- racer (experiment which pairs create the most static charge that repels or attracts)
Myles- timer (timing the racers)
Envision:
- What rules do you want to have regarding your collaboration? (e.g. equal workload, deadlines met etc.)
We will equally distribute the work (each person has their role).
We will finish our work in time.
- What will you do if these rules are not being followed?
If the rules are broken, we will discuss as a group and come up with a solution.
- Do you have any questions regarding the task that need to be answered? Do you understand the requirements of the project?
Yes, we understand the requirements of the project.
- What goals for the task do you have for the group?
-Win the race
-Collaborate nicely with your team
-Don’t get hurt
-Don’t hurt others
-Divide all work equally
-Be understanding of the opinions of others and don’t judge them
- What will the final outcome or product look like and what information is needed to accomplish the task?
-You need to know which materials create the most static charge that repels, to push the car to race and win.
-A chart of information which shows whether or not this pair of material repels or attracts, and how much it attracts or repels.
- If you were to break down the task into manageable pieces, what would the timeline look like, knowing that the project is due March 7? (add names and date Experiment with all the materials and decide which one is the best material to use. (First 2 days)
- Do the experiment to see what material of rod works best with what material of cloth to create the best static charge (Riley 3/5, 3/6)
- Record data (Jenny 3/5, 3/6)
- Analyze data (Myles 3/5, 3/6)
- Reach a decision what material of rod works best with what material of cloth to create the best static charge (Zeena 3/6)
- Participate in the race (All 3/7)

We decided that Lucite and fur is the best material to use for the race.
Examine:
How did your engine work?
Lucite charged by fur attracted the ruler and made it to spin.
How could you increase the velocity of your race?
I could have increased the velocity of my race by placing the lucite horizontal and closer to the ruler. Therefore, more surface area of lucite would attract the ruler stronger.
Detergents- Solution Fluency
Define:
In science 9 class, Mr. Horton assigned us groups and asked us to make a hypothesis of which detergents work the best and if it is worth it or not. There were 4 different detergents given: Woolite, Sunlight, Tide, and Ultra-fresh. Our group used a coffee stained cotton to figure out which detergents will work best to remove the stain. Also, if the detergents perform best in cold or hot water. The hypothesis was that the Woolite in hot water will work the best to clean the coffee stain cotton.
Discover:
What kind of stain are we using? We decided to use coffee stained cotton.
What kinds of detergents are we using? We used Woolite, Sunlight, Tide, and Ultra-fresh.
What kinds of water will we be using? We decided to experiment both on cold and warm water.
To gather some information and investigate, we also asked what kind of ingredients does the each detergents contain? According to the research we found out that unlike other detergents, Woolite contained ingredients like anionic surfactant and thickener which preserves the texture of clothing and removing greasy stains. All the other detergents had similar ingredients of removing stains like sodium carbonate, sodium chloride, and sodium dodecylbenzene surfactant.
Deliver:
As the result, all the detergents in hot water performed better than in cold water. Ultra-scent in hot water worked the best and the tide in hot water worked the second best. Therefore, Ultra-scent is worth it.
Debrief:
I think the experiment had been improved if one person have added 5 drops of each detergents to make the amount more accurate and equal. Also, we only tested the coffee stained on cotton so we don’t know what will happen on different material cloth and different stain. Overall the lab experiment process went through very well.
