Water pollution video

In Humanities class, I made a Capstone video that is about water pollution. I tried to make my video organized well and to give audience about the message of the video clearly and powerful. What I need to improve is that I need to put more details of how water pollution seriousness is.

Catapult Reflections

In Algebra class, I made a catapult with my partner that can consistently launch the ball in a straight line. Our success criteria were to make the catapult minimum vertex height of 0.3m, freestanding and has a stable structure. We thought that the design would be suitable because it only requires materials that are easily found, and meets our success criteria.




Elevator Pitch

This is my elevator pitch for the capstone project. I introduced my topic, water pollution, problems with this topic, survey results, and solutions to this problem briefly.

Reflection: I tried to fill in all the things I had to write in my elevator pitch in a powerful and brief way to make the audience realize how water pollution is a serious problem in our world. I tried to do really well, but I couldn’t speak loudly and couldn’t eye contact with the audience since there were many people in front of me. I clearly memorized what I need to say, but I forgot some of them during the speech. I was so nervous that I had never experienced this before. What I need to improve is that I need to practice eye contacting people and make it more fluently next time.



Science journal entry 4

Our group worked on 4 prototypes for our polymer project.

Prototype #1: 1cm of White Glue, 25ml of Laundry Detergent, 10ml of Borax

Claim: It does not meet our requirements for a phone case.

Evidence: It makes different chunks because it doesn’t stick to our hands or to each other. This should be stick on our hands a little.

Reasoning: They are not joined together and cannot be attached to the phone.

Prototype #2: 2cm of White Glue, 25ml of Laundry Detergent, 10ml of Borax

Claim: It does not meet our requirements for a phone case.

Evidence: It was so sticky that when we touched it, it stuck in our hands and was difficult to get it out. In addition, it was not elastic because it was attached to the table. 

Reasoning: We need an explosive polymer to keep the phone case from breaking, but this prototype is not resilient and does not meet the standard.

Prototype #3: 1cm of White Glue, 25ml of Laundry Detergent, 5ml of Borax

Claim: It does not meet our requirements for a phone case.

Evidence: It was soft and feel good, but it didn’t bounce much. This polymer was all suitable for the physical properties that we wanted to make except for not bouncing. It should be bouncing a lot.

Reasoning: We need a powerful polymer to keep the phone from breaking.

Prototype #4: 1cm of White Glue, 20ml of Laundry Detergent, 5ml of Borax

Claim: It is the best match for our goal to make a phone case.

Evidence: It bounces a lot, not soft, cannot be stretch out, not too sticky.

Reasoning: This evidence meet our requirements and we think that this is the best prototype for our polymer project.

After we finished this project, we learned lots of characteristics of each of the materials. What we made was very successful in making a phone case and meet the goals which were bouncy, not soft, cannot be stretch out, and not too sticky. Even though we had a hard time thinking about matching our topic, these experiments let us know lots of features and made us good experiences. I really enjoyed doing this polymer project since we could increase our creativity and be able to rethink the features. What we need to improve is that our group had to keep the polymers well. I think we need to be fully prepared with these polymers because we lost it once and we had to do it again.

Our group decided to make a phone case using our slime which is a mixture of Gloop and Bogger. We succeeded in what physical properties that we wanted to put; able to bounce, not soft, cannot be stretch out, and not too sticky.

  1. Ingredients

First, 1cm of White Glue

We noticed that white glue can make the slime bounce and cannot be stretch out in the first experiment. To success the physical properties that we wanted, we decided to put white glue in the slime at the first stage.

Second, 25ml of Laundry Detergent

At first, when we make a Boogers, we realized that physical properties of Boogers were all satisfied with what we wanted except for sticking. Therefore, we determined to use same ingredients with Boogers and then put other ingredients.

Third, 10ml of Borax.

When we make a Gloop, we suspected that it does not make sticky if we put borax in the slime. At first, we added 5ml of borax and also more than 10ml of borax, but it was not suitable, so we decided to add 10 ml. This was just right and it did not get too sticky or out of shape.

  1. Method


  • Put 1cm of white glue in an empty cup ( It is free choice to put in coloring )

  • Pour 25 ml of Laundry Detergent in the cup which already has white glue in it.

  • Mix well

  • Pour 10 ml of Borax into the cup.

  • Mix well until it is in shape

  1. Results


Science journal entry 2


The goal of our polymer is to prevent an object from breaking. Our target market audience can be everyone because this will be not only beneficial for parents who have their children but also can use it as a plaything for young children. When parents are outside, they will be anxious if their children break something in the home and our polymer will help this problem. We wanted the physical properties to include bounce, not soft, cannot be stretch out, and not too sticky.

PVA+Landary+Borax was the first polymer we made. The characteristics were soft and after we made it, we realized that this would not reach our goal. Then, we made PVA+ White glue+Borax for the second polymer. The characteristic of this polymer was sticky but this polymer did not work well because it was too sticky to touch with hands. Our third polymer was white glue+Landuary. This polymer was all suitable for the physical properties that we wanted to make except for just one thing: not bounce. Then what we experiment last time had come into our mind and we think about what the characteristic of materials in the class for a while. Therefore, we decided to put borax in the third polymer. Finally, it was all fit for the physical properties that we wanted and it worked well so we determined to make this polymer.

Science journal entry 1

A polymer is a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together. For example, many synthetic organic materials used as plastics and resins. There are lots of different types of polymer in these two categories: natural and synthetic. Natural polymers are found in plants and animals such as proteins, cellulose, starch, resins, and rubber. A variety of synthetic polymers as plastic, synthetic fibers, and synthetic rubbers are examples of man-made polymers. Synthetic polymers are produced by chemical reactions, termed “polymerizations.”

Polymerization is Chemical reaction in which two or more small, similar molecules are combined to make larger molecules. Polymerizations occur in varied forms but such reactions consist of the repetitive chemical bonding of individual molecules, or monomers (a molecule that “can undergo polymerization thereby contributing constitutional units to the essential structure of a macromolecule.)

These are the synthetic materials that we use in our society: Bioplastics (As we are often reminded, plastics do not degrade and are a very visible source of environmental pollution.), self-healing polymers (No matter how carefully we select materials for engineering applications based on their ability to withstand mechanical stresses and environmental conditions, they will inevitably fail.), plastic electronics (Most polymers are insulators and therefore don’t conduct electricity.), and smart and reactive polymers (Gels and synthetic rubbers can easily adjust their shape in response to external stimuli, which means they are able to respond to changes in their surroundings)


Sources I used:


Revolutionary Voices Journal

I wrote about the French Revolution journal and the character’s perspective of this journal is peasant which belongs in Third Estate. There were lots of conflicts and causes. What I learned by writing the journal was I can more understand the perspective of the character. There were interesting effects in my journal after the character has the conflict. So enjoy my French Revolutionary Journal!

French Revolution Common Craft Video

I and my group members made a video about the French Revolution. There are lots of information about the characters and the conflicts. We used flashbacks at the beginning of the video and then we put the story in order.
Enjoy our common craft video!!!

Non Fiction: Frequently asked questions about loneliness

This book is about loneliness by Robert Greenberger. Recently, people at all ages are feeling “loneliness” with their romantic partner, friends, and by a large crowd. There is a vast difference between being alone in a room and feeling lonely. People feel this feeling of loneliness when they feel powerless, separated from other people, nervous, empty, sadness, and others. There are lots of solutions to solve out this emotional feeling.


According to the University of Chicago report, “Loneliness can be a genetic trait, meaning that if someone in your family has suffered from loneliness, you may be more susceptible to it.” This quote shows that loneliness is coming from your family which means that if your family had this kind of feeling, it is also possible to have loneliness to you. There are relatively connected with depression, anxiety, and loneliness. Even though the meaning of these three words are similar, they have small difference between these words. To explain more, depression can be pronounced in certain seasons but loneliness is a constant state. There are some main causes of loneliness. One reason for this is huge changes in society.


Feeling loneliness means you are alone. If people are in isolation, they should reach out to friends and family and get involved like talking about what they experienced. In addition, do not try to identify yourself simply. This will make the feeling of loneliness worse. Getting a pet is another example of solution. According to the Centers for Disease Control and Prevention, these days, people are having pet relationship to have health benefits.
