Throw a ball -James Henry Gary

1. What did you learn from this activity? How is that relate to the concepts we learned in Algebra I?

This activity is related with quadratic function

2. What did your group do well?

Nice video and good collaboration when we record video and audio by iMovie.

3. What were some of the challenges your group faced?

Our group challenged when we took a video. We can’t take a video well.

4. What aspects of this activity could your group improve?

We can put more effects or explanations in our video (iMovie)

5. How could you do it differently if you are giving another try?

Use other function instead of quadratic function (Linear function, exponential function)

Our prototype: non-newtonian fluid

Polymer journal 5

The procedure of our prototype:

1, add 200g of cornstarch (powder)

2, add 100ml of water

3, stir the mixture slowly

4, If you want to add some color, add 2 drops (paint)


-It is liquid but when we touched it becomes solid.


-when I poked it return to old form

– when it is solid it is quite hard


Claim: The non-newtonian fluid is the most successful prototype that we have used. Our prototype has advantages and also has disadvantages. First, when we punched the prototype hardly, it becomes solid, but when we poked it slowly it becomes liquid. It is an excellent property to protect the laptop and it is protective. But there are some disadvantages. First after 2-3 days, it dries. After 2-3 days our prototype lose the function (Becomes hard and soft) Our prototype’s function is nice to protect our laptop but it will dry after 2-3 days. Our product good, however we need to fix disadvantages.


We could usually see corn-starch on our kitchen, but I didn’t know that when corn-starch and water mixed, (We called Oobleck) Noramlly, it is liquid but when we touched it it becomes solid. This is a first time that I know this product. First, we don’t know the ratio to make non newtonian fluid.  Our group tried and tried to make non newtonian fluid.


100% environmental and has a special function (punched the prototype hardly, it becomes solid, but when we poked it slowly it becomes liquid.)

Capstone video

This video is made by Leo and James Park (8-6)  Talking about causes of air pollution and solution to solve this problem.  Leo is a person who doesn’t know about air pollution. And I am a clever person who is teaching Leo about air pollution.




  • My biggest success was I made Arduino(To move Owl’s wings)

  • My biggest obstacle was connecting Arduino to wings.

  • Skills that I learned or developed were how to use or code Arduino

  • One thing I’d like to change is a collaboration

  • If I did this again, one thing I would do differently is changed the partner ​

  • One piece of advice I would give a future student doing this project is to be careful

  • Overall, I think this product was successful because we made a product(owl robot)

Journal 3 (Science)

Physical properties I want to see in my polymers are:

1, It is hard enough to protect the laptop.

2. If it dries it still has a function.

Plan to develop prototypes.

I will make my laptop case by mixing cornstarch and water. After I mixed that 5-10 minutes, the mixture will be sticky. And if you put your fingers slowly into the liquid, you could stir them. But if you punch or poked hard, you can’t stir well. It turns to solid.

To test the effectiveness of my prototype, we need to think 2 things.  First, is it hard enough to protect the laptop? Second, after it dried, it still has a function? If it has both features what I want, it will be the perfect prototypes to our group.

Journal2 (Science)


Today we made laptop case. We mixed cornstarch and water.(Cornstarch (66%) Water(33%)) Stir mixture(cornstarch and water) for 10 minutes. After we stir 10 minutes, the mixture becomes sticky liquid. And we poured that liquid on the laptop case. After I poured the liquid becomes solid and if I pressed it, it restored to the original condition. But there is a problem. After 10 minutes, solid lost its function. We can’t use that material.                                                                                  Today we failed and we need to find some new materials to make a laptop case. Finding a new material is the first object of our group.

What are the polymers and how are they made?

Polymers is a substance which has a molecule structure built up chiefly or completely from a large number of similar units bonded together.

When many molecules of a simple compound, made from joining together many small molecules called monomers. A chemical reaction bonding monomers together to make a polymer is called polymerization.

What are synthetic materials, and where do they come from?

Synthetic materials are fabrics manufactured in factories using chemical synthesis. They are also known as artificial or man-made fabrics. Synthetic fibers are made by the joining of monomers into polymers.

Basically, there are two basic types of polymerization. Chain-reaction and step-reaction polymerization. One of the most common types of polymer reactions is a chain reaction. This type of polymerization is a three-step process involving two entitles.

There are four kinds of biological macromolecules. They are carbohydrates, lipids proteins, and nucleic acids. These polymers are composed of different monomers and serve different functions.


Also, there is polymers name synthetic organic polymer. Now, let’s know synthetic organic polymers specifically. The seven most common types of synthetic organic polymer are low-density polyethylene, high-density polyethylene, polypropylene, nylon, and Teflon.

FEED: Feed is a device that put in all humans’ brains, in the book feed by M.T Anderson. With Feed, we could do anything, just like a phone in our brain: chatting with friends and watching videos, for example.

I think Violet is the most important character in this book because Violet is Titus(Main character)’s girlfriend and she had a lot of influence on Titus. Also, she has a clear idea of she’s own and she said her opinion to Titus. For example, before Titus met Violet, he thinks feed is awesome. But, she isn’t. She always thinks humans need to be wary of feed because it is very dangerous

Things about diet pills

Diet Pill

Would you recommend this to a teen?

No, first there are some harmful ingredients in Diet Pill.

Those ingredients increase heart rate and high blood pressure. Even FDA banned those ingredients because there are harmful. So, I think teens may not use diet pills.

Long -term effects

The good thing is people could lose weight in a short time. But, it could cause serious consequences. Scientists found that taking diet pills makes people six times more likely to get pulmonary hypertension, a disease that increases pressure on the arteries in your lung. It is a breathing problem.

Short-term effects

And if you keep taking diet pills you will be addicted to pills and it will be ineffective than before. Also, you will depend more and more on drugs than exercise.
