MY TOPIC : OLIGODENDROCYTES
1) What questions did you need to research in order to research your topic?
What is an oligodendrocyte?
Why are oligodendrocytes important?
Where are oligodendrocytes found?
What do oligodendrocytes do?
2) What new or familiar digital tools did you try to use as you worked through this project?
I used Google as well as Gale Engaged Learning to find my information.
3) What was the process you used to investigate the topic?
I established questions first. After I searched up oligodendrocyte to see what would come up on Google and Gale. Next, I made questions and researched.
4) How did you verify and site the information you found?
For the information I found on Gale, I did not verify the information because I know it’s already pre-filtered for me. On Google, I checked the article date and it’s author. I also checked the website and what it was about. I verified by checking a few other sites to see if the same information was given.
5) How did the process of completing this challenge go? What could you have done better?
The process was relatively easy for me because I have some experience with this. I did a couple of things in my English class, which was first semester, about finding valuable information so I did not struggle with this challenge. I think I could have used more websites on the school library page rather than going on Google but the information I found on Google was easier for me to understand.

Meiosis – division of cells
- What I made: https://www.jamieoliver.com/recipes/pasta-recipes/easy-sausage-carbonara/ This is a pasta recipe I chose because I thought it was a great recipe to make because of it’s ingredients. It has little ingredients and they are ingredients that most people have in their homes. I think it’s a great recipe for people who want something simple and delicious to make. It is a main appetizer.
2. Main Appetizer: https://www.jamieoliver.com/recipes/rice-recipes/crab-asparagus-risotto/
I chose this rice recipe because it’s gluten free and looks tasty. I would like to go gluten-free and this recipe seems perfect for people who are sensitive to gluten or are gluten-free.
3. Main Appetizer: https://www.jamieoliver.com/recipes/pasta-recipes/lemony-courgette-linguine/
I chose this pasta recipe because it does not have many ingredients and is good for anyone to make. I think that this recipe with some chicken and salad would make a healthy and nutritious dinner.

Here is my Sway Presentation about Cellular Data:
3 tablespoons olive oil, divided (45 ML)
1 (15-ounce) can cannellini beans, drained and rinsed
1 teaspoon kosher salt, divided (15 ML)
2 teaspoons za’atar, divided (30 ML)
1 medium bunch Swiss chard (about 10 ounces), stems removed and leaves thinly sliced
2 cloves garlic, minced
1/4 teaspoon red pepper flakes, plus more for serving (1.25 ML)
1 tablespoon freshly squeezed lemon juice (15 ML)
4 large eggs, poached
Heat 2 tablespoons of the oil in a large frying pan over medium-high heat until shimmering. Add the beans, spread into an even layer, and cook undisturbed until the beans are lightly browned on the bottom, 2 to 4 minutes. Add 1/2 teaspoon of the salt and 1 teaspoon of the za’atar, and stir to combine. Spread the beans out again and cook, stirring as needed, until golden-brown and blistered on all sides, 3 to 5 minutes more.
Add the remaining 1 tablespoon oil to the pan. Add the chard, remaining 1/2 teaspoon salt, remaining 1 teaspoon za’atar, garlic, and red pepper flakes. Cook, stirring occasionally, until the chard is wilted, 3 to 5 minutes. Remove the pan from the heat, add the lemon juice, and toss to combine.
Divide the beans and greens among 4 bowls, and top each with a poached egg and more red pepper flakes. Serve warm.
Serves 4 to 6
2 cups whole milk (475 ML)
2 cups water (475 ML)
1 cup yellow cornmeal (235 ML)
4 to 5 strips thick-cut bacon (about 1/4 pound), roughly chopped
1 medium red or yellow onion, thinly sliced
1 large bunch collard greens (14 to 16 ounces), stems removed and leaves sliced into ribbons
1/2 teaspoon salt (2.45 ML)
1/2 to 1 cup chicken broth (118 ML to 235 ML)
4 to 8 large eggs (1 to 2 eggs per person)
Salt and pepper
Before cooking the greens, get the polenta going. Bring the milk and water to rapid simmer in a medium sauce pan. Add the cornmeal in a steady stream, whisking as you go. Season with salt and pepper (about a teaspoon of salt and a few grinds of pepper to start, to taste). Continue to cook, whisking, until the polenta begins to thicken.
Reduce the heat to low and cover. Every 10 minutes, uncover the pot and stir the polenta, making sure to scrape the bottom and corners of the pan. The polenta is done when its creamy and no longer tastes raw, after 20 to 30 minutes. (If the collards aren’t quite done yet when the polenta is finished, you can turn off the heat and cover the pan to keep the polenta warm. When you are ready to serve it, stir to loosen it up and add a bit more milk if necessary.)
Warm a large skillet over medium heat and add the chopped bacon. Cook until the bacon fat has rendered and the bacon is getting crispy. Move the bacon to one side of the pan and pour off all but a tablespoon or so of the bacon fat.
Add the onions to the pan with the bacon and continue to cook until the bacon is as crispy as you like it and the onions are soft and beginning to caramelize, 8 to 10 more minutes.
Raise the heat to medium-high and add the collard greens and 1/2 teaspoon of salt. Stir and toss until the greens are coated in the bacon fat and beginning to wilt. Add 1/2 cup of the chicken broth, scraping up any brown bits from the bottom of the pan. Reduce the heat slightly and cover the pan. Cook for 5 to 10 minutes, adding more chicken broth if the mixture gets dry, until the collard greens are dark green and soft. Taste and add more salt and pepper as needed.
Melt a little butter over medium heat in a non-stick or cast iron skillet. Fry the eggs in batches.
To serve, put a big scoop of polenta on each plate and top it with the greens and bacon mixture and a fried egg or two. Sprinkle with salt, pepper, and hot sauce, if desired.
1 tablespoon unsalted butter (1/2 ounce; 15g ; 15ml) softened, divided
1 English muffin, split
1 slice high-quality Canadian bacon
Nonstick cooking spray
1 large egg
Kosher salt and freshly ground black pepper
1 slice American, cheddar, Swiss, or Jack cheese
Spread 1 teaspoon butter on each half of the English muffin and place halves in a 10-inch nonstick or cast iron skillet over medium heat. Cook, swirling muffin halves and pressing gently to get good contact with pan, until both pieces are well browned, about 4 minutes. Transfer to a sheet of aluminum foil, split side up.
Melt remaining 1 teaspoon butter in the now-empty skillet and increase heat to medium-high. Add bacon and cook, turning frequently, until browned and crisp around the edges, about 1 1/2 minutes. Transfer bacon to lower muffin half.
Place the lid of a quart-sized, wide-mouthed Mason jar (both the lid and the sealing ring) upside down in the now-empty skillet. (The side the jar screws onto should be facing up.) Spray the inside with nonstick cooking spray and break egg into it. Poke the egg yolk with a fork to break it and season with salt and pepper. Pour 3/4 cup (180ml) water into the skillet, cover, and cook until egg is set, about 2 minutes.
Using a thin spatula, transfer Mason jar lid to a paper towel–lined plate. Pour excess water out of the skillet and return it to the stovetop with the heat off. Flip Mason jar lid over and gently remove it to release egg. Place egg on top of bacon and top with cheese slice. Close sandwich, wrap in aluminum foil, and return to the now-empty skillet. Let it warm up in the skillet for 2 minutes with the heat off, flipping occasionally. Unwrap and serve immediately.
To make a healthier alternative, I would use Turkey Bacon instead of real bacon because it has less fat. To make this gluten-free, you could use a gluten-free English Muffin.
(Information was taken from the Laundry Detergent Experiment – Science 9 – Block B – Semester 2 – Mr. Horton for this post. )
The challenge that I investigated was which laundry detergent cleans better. Does a higher price point always equal a better clean? Or does it have something to do with the ingredients? I investigated by using warm water and multiple laundry detergents with a coffee stained rag stain.
- 15 ml of each Detergent using Hot Water
- 5 Beakers
Hypothesis: We think that the more expensive detergent will wash better because of its higher price point.
Procedure (Stirring for 10 Minutes Each)
- Stain rag with Coffee the day before.
- Cut up rag into 5 pieces.
- Wash a rag in hot water using NO DETERGENT (Control Group).
- Wash a rag in hot water using 15 ml of Detergent (No Name Brand).
- Wash a rag in hot water using 15 ml of Detergent (Tide).
- Wash a rag in hot water using 15 ml of Detergent (Sunlight).
- Wash a rag in hot water using 15 ml of Detergent (Woolite).
- Compare to see Results!
The first question I asked were what ingredients were in the laundry detergents? Did laundry detergents with a certain ingredient clean better than with a one that didn’t have the certain ingredient? With some research, I was able to find the ingredients for Tide, Sunlight and Woolite but could not find the ingredients of the No Name brand.
No Name Brand Ingredients: UNKNOWN
- alcoholethoxy sulfate
- linear alkylbenzene sulfonate
- propylene glycol
- citric acid
- sodium hydroxide
- alcohol sulfate
- polyethyleneimine ethoxylate
- sodium fatty acids
- diquaternium ethoxysulfate
- diethylene glycol
- laureth 9
- alkyldimethylamine oxide
- disodium diaminostilbene disulfonate
- sodium formate
- calcium formate
- polyethylene glycol 4000
- Liquitint™ Blue (a dye)
- Sodium Laureth Sulfate
- Ethoxylated Lauryl Alcohol
- Sodium Dodecylbenzene sulfonate
- Sodium Citrate
- Sodium Cocoate
- Alkylbenzene sulfonic acid
- C12-16 Alcohols Ethoxylated 7EO
- Sodium laureth sulfate
- Sodium hydroxide
- Coconut Acid
- Tetra sodium glutamate diacetate
- Sodium chloride
- Proprietary inert filler
- Sodium formate
- Butylated hydroxytoluene
All of the detergents have a variety of ingredients. Since Tide cleaned our rag the best, I believe that it perhaps may not be a certain ingredient that cleans the best but rather the number of ingredients. Compared to the other detergents that we know the ingredients of, Tide has the most. More ingredients could mean a better clean but this may not be the best. Too many chemicals is not beneficial to our health and we must lookout for the harmful ingredients in the detergents we buy.
The second question I asked was how long should we wash our rags for to see the results? If we didn’t wash the rags long enough we would not see any results but we also didn’t want to be washing our rags for too long. I found that 10 minutes is enough time for the stain to dissolve and we were able to see the results.
After the rags dried over the weekend, my group concluded that the Tide detergent cleaned best. Although the stain was not completely gone, it had mostly faded away. Though I must admit, the other detergents came close to Tide. My hypothesis was proved wrong by these results. I felt confident that Woolite will clean best because it was quite expensive compared to the price of the other detergents. This experiment showed a good example of how a higher price point does not always equal better quality.
As reflected in the post, I am proud of how well the experiment went and the results and work produced was of high quality. A lot of time and effort was put into the experiment and the hard work definitely payed off!
Group Members: Andrea, Claire, and Theo.
Footage of The Race and Interviews:
Our Motto: Encourage Wild Ideas
The first step to successfully accomplishing the project was to create our group contract. We began by determining the strengths of each of our group members. Andrea’s strength was adaptability. She is able to adapt quickly to any situation or circumstance. Claire’s strength was time-management. She manages time well which helps us use our time wisely. Theo’s strength is creativity. As an artist, she thinks out of the box and can help use find new techniques to win. My strength is leadership. I took on the leadership role because I like to be a leader and help my team as much as possible. Next, we divided the work. Theo and Claire were racers. Andrea was the reporter and I was the timer. We made a few rules regarding our collaboration. They were:
- Try to give everyone an even amount of work to do. One person will not have to do all the work while the rest of the group members slack-off.
- Listen to each other’s ideas. Even if you don’t necessarily agree with that idea or vision, listen and take away the parts you like and find a way to add it to your project.
- Consider everybody’s ideas. This ties in with the second rule of respecting everybody’s ideas.
If these rules are not being followed, then the team member that doesn’t complete their part does not get marks for this assignment. On March 6th we completed all of our research and we raced on March 7th. Our initial goal was to try our best and win the fastest time in our block and that was exactly what we did!
