Part 1: Cell Story
Hello, I am myocyte, people used to call me muscle cell as well. I can be found in your muscle tissue. I have a big family and friends: cardiac, skeletal, and smooth muscle cells, with various properties.
Cardiac can be found in your heart muscle, the major function of cardiac muscle cells is to contract so as to enable the heart to pump blood to all the parts of the body.
Skeletal are attached to bones, include the large muscles of your arms and legs, and the smaller muscles of your face. Skeletal muscle cells give power for movements, stabilize your joints and enable you to maintain an upright posture. Skeletal muscle cells come in slow-twitch and fast-twitch varieties. Slow-twitch muscle cells are adapted for endurance activities and maintaining posture. Fast-twitch muscle fibers are adapted for rapid movements and activities that require maximum efforts, such as jumping and lifting.
Smooth muscle cells can found inside blood vessels and around the pupil of the eye, perform automatic movements in the hollow organs of your body. For example, they move food through your digestive system, expel urine from your bladder and are responsible for contractions of the uterus when delivering a baby. Smooth muscle cells are also found inside blood vessels and around the pupil of the eye.
This is my selfie and my structure.
Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis.
We serve a remarkable variety of functions in your body, many of them occurring involuntarily. The specialized structure of the 3 types of my family in the human body enables their functional purposes. Skeletal muscle cells are primarily specialized for voluntary movements, like dancing or snapping your fingers. Smooth muscle cells are structured to produce involuntary movement, such as propelling food through your digestive system. Cardiac muscle cells keep your heart beating and have features of both skeletal and smooth muscle cells.

Part 2: The Making of the Cell Story
Solution Fluency on Science LAB
Andrea So Block B
The challenge that we had to do was to test the effectiveness of 4 different types of detergent. Or also to test the cost is worth for the most expensive one, like would the other’s which are cheaper work better than the most expensive one? We had to do a fair test to test it out.
We had questions like:
What’s the difference of using cold water and hot water?
How we solved it: We searched online on the difference and we believe that it’s warm water that can somehow melt own the stain from its heat but cold water don’t.
How do we record and be able to identify the clothes after they are being taken out from the beaker? As there were only labels on the beakers not the cloths.
How we solved it: We marked it down on one of our phones typed the names of the detergent from left to right, as they were pinned on the board, this made it easier and we won’t get in trouble for not being able to figure out which is which.
The result was that the woolite detergent one washes off the stain the best, it is also the most expensive.
(I apologise that that this pic couldn’t be rotated no matter what :/)
Overall, I enjoyed the lab a lot because at least I didn’t have to sit down and do work at my desk the whole block. Rachel was really active and she basically started organizing stuff even before me and Mckayla have finished understanding what Mr. Horton said. The preparation was really smooth and we organized really well in order for the experiment to be smooth the next day. During the experiment, the hardest part wasn’t figuring out who is going to do which jobs but it was mixing for straight 15 minutes. Honestly my arms were sore after mixing non-stop for so long that day, anyways I liked the experiment, it was interesting to find out which detergent works the best because it’s actually helpful for daily life, now I know which detergent should tell my mom to buy.
Our task is to charge different material of rods with some fabric and find out the strongest pair of conductor.
Control variable: stand
dependent variable: piff
independent variable: different materials of rods and different materials of fabric
|Silk||No effect||No effect||Lightly attracts||Slightly repels||No effect||Slightly attracts||No effect||Slightly Repels|
|Cotton||No effect||No effect||Attracts||Slightly attracts||No effect||Strongly attracts||No effect||Slightly attracts|
|Polyester||No effect||No effect||No reaction||No reaction||No effect||No effect||No effect||Attracts|
|Fur||Slightly attracts||No effect||Strongly repels||Strongly repels||No effect||StronglyRepels||No effect||Slightly repels|
|Plastic||No effect||No effect||Slightly Repels||No reaction||No effect||Very slightly attracts||No effect||StronglyAttracts|
|Wool||Slightly attracts||No effect||Slightly attracts||Strongly attracts||No effect||Somewhat attracts||No effect||Slightly repels|
Ebonite and plastic is the strongest conductor at attracting.
Lucite and fur is the strongest conductor at repelling.
How did it happen?
The piff get attracted from the charged rod because the piff got some electrons from the rod and both of them have negative charge.
The rod pushed and repelled the piff because they’ve got different charges.
I think I had very great experience when I was collaborating with Claire, Samira and Theodora. We had equal workload and everyone was on task, no one was playing with their hone during the experiment. Samira and Claire collected the result and made a clear table. Theodora and I did the experiment with different materials. I felt so proud of our work and results.
Here’s our video of explaining Meiosis and Mitosis
The dish that I cooked for the take home is the Stir-Fried Egg Noodles with Chicken, I wanted to cook this dish because my family and I like stir-fry noodles a lot, kind of because of our heritage as we are Chinese, I have thought of making pasta but then I decided to choose something that would represent my ethnicity and my family would like so that i could serve them some for dinner. The ingredients were also easier to get.
You can pick up all the ingredients for this recipe at the salad shelf and it takes less than 15 minutes to prepare. The dish is quick, easy and healthy packed with nutrients.
Serves: 1 person
Here are the recipes for the other two dishes
Take your risotto to the next level with this flare of Indian spices.
59 ml cup dried curry leaves
1 tsp brown mustard seeds
1 tsp green cardamom pods
2 cups thinly sliced mushrooms, a combination of oyster, shiitake and portobello
237ml arborio rice
118ml cup dry white wine
2 Tbsp butter
crushed dried chilies
1. Bring stock to a simmer over medium heat. Turn to low and keep hot.
2. Melt butter in a large saucepan and when it begins to foam add onions and cook until they are soft, about 3 minutes. Add spices and continue to cook for 1 minute. Stir in mushrooms and cook until they begin to caramelize, about 5 minutes. Add rice, stirring so it is well coated with butter and then add the wine, stirring constantly as it is absorbed into the rice. Begin to add the hot stock a little at a time and continue to stir constantly as it is absorbed into the rice. The rice is done when it is tender and creamy in consistency, about 30 minutes. Turn off heat and stir in 3 tablespoons of butter and season with salt. Spoon into wide shallow bowls and garnish with shavings of parmigiana and a scattering of dried chilies.
Reason of choosing this recipe: My second favourite cuisine is Italian and I have never tried making risotto, I’ve eaten it for way too many times but just have never cooked it.
