Humans of ISB #1

The final product of the ignite week”Humans of ISB” is a large charcoal painting of someone in ISB.First, I chose to interview librarians, middle school and high school students form ISB. I chose 6 students and asked them the following two questions. 1 what is the happiest moment of your life? 2 what is something you are worried about? Than I took a black and white portrait of each of the students I interviewed. I choose one out of the seven students I interviewed for the exhibition. This is a portrait of a 7th grader that is new to ISB. The inspiration of this project came from “Humans of New York”. The author of this book took pictures of people in New York, and asked them questions that expressed feelings. For example “What are you most afraid of” or “What is the happiest moment of your life”.

Theses are some of the people I interviewed, the last person I interviewed didn’t want me to take their picture.

The picture below is the one I chose to draw. I chose to draw this student because I thought the happiest moment of her life is interesting.

” The happiest moment in my life is winning the international english olympiad award.”

Our design cycle:  

Define and inquire

Develop and plan

Create and improve

Exhibit and Reflect

I’m at the step develop and plan in our design cycle. I interviewed and took pictures of students in ISB (define and inquire). I picked the portrait that a will use for the charcoal panting with a quote (develop and plan). For the next step in the design cycle, I will be creating a large charcoal painting based on the portrait I chose.

Project Collisions Final Drop

Looking back on Collision, I learned that the most important step in designing a product as a group is to fully agree on an idea before we start to make it. For example, my group and I had to redo drop 0 three times because we kept on changing our minds about whether we should put our design in a box, tow boxes or a bag. However, we learned from our mistake when we did drop 1 and drop 2. We all made our own models then added all these ideas together and designed according to our group model. It’s important to test and collect data when you design because usually for our first design, we are guessing what might work form what we think might happen. When we test and collect data, we see what happens and we find the parts of F.A.I.L. and we try to improve our design by finding solutions to these problems. For example, during our initial drop, the average force of our product hitting the force plate is around 600 N (3 tries), the maximum velocity is around 11 meters per second. So, we decided to add a parachute to slow the fall of our package. The data that we collected of our new package is about the same as our initial drop. We realised our parachute is too small after doing some research on skydiving. We added a second (much larger) parachute to our design. This time when we tested it, the average force of our product hitting the force plate is round 228.6 N our package lowered more than 50% of the force we collected in our initial drop.

Project Collisions Drop 1

Our team constructed the first design using wrapping paper, string, a bag, a small cardboard box, and tape.  Multiple drops took place and we noticed that the parachute is too small and isn’t working as expected. The force of the drops was still very high and the speed for the package to fall the last 2 meters are still fast.

In order to improve our design, we paid attention to area where it failed. The following “FAILS” happened during the drop:

The parachute did not decrease the force of the drop. The Time it took the parachute to fall the last two meters stayed the same.

Drop 0 Data Table:

  Mass of Box (g) Force Accuracy Velocity Time (sec)
Drop 0 A 51.6 132.9 Barely on the force plate 12.6


Drop 0 B 51.6 126.4 Barely on the force plate 10.4


Drop 0 C 51.6 669.9 On the force plate 10.7





Drop 1 Data Table:

  Mass of Box (g) Force Accuracy Velocity (m/s) Time (sec)
Drop 1 A 51.4 682.8 On Force Plate 10.6 0.3
Drop 1 B 51.4 724.9 On Fore Plate 10.4 0.3
Drop 1 C 51.4 302.8 Barely on Force Plate 10.5 0.3


Some things also went well. successes include we have better accuracy.

For our next design, we will improve upon the first prototype by adding a larger parachute to our design.

Wenyu River Field Study – Data Collection 4

Today, my group and I didn’t find any insects in both quadrant 1 and quadrant 2. I think it has something to do with the temperature. We couldn’t take any pictures of our quadrant because Katherine’s  phone ran out of battery.

Data table

As the temperature is dropping, the number of bugs are also decreasing. In November, we didn’t find any ants in our quadrants, but we did find two spiders in quadrant two. Today, we didn’t find any bugs in both quadrants. I wonder if the number of bugs will stay zero the next time we have a field study.


Project Collisions Drop 0

In Project Collisions, I am creating a system to deliver laptop chargers and portable chargers by drones. The drone will release the package from a height up to 10 meters and my job as an engineer is to develop a solution so that the package is protected in its fall.

For Drop 0, a package with the dimensions of Length 36cm width 26cm was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold a charger in a small box. Inside, items are organised like this:

The purpose of Drop 0 is to get baseline data about our package. The group developed a testing procedure so that we can be consistent on how data is collected throughout the design cycle.


  1. Plug the force plate wire into the laptop
  2. Carry bag to recognised drop area
  3. Use ruler to make sure distance package away from area is correct (40 cm)
  4. Hold the package so that it’s directly above the force plate
  5. Start to record the last two meters using quick time player, push play button
  6. Drop package at 5 meters
  7. Measure distance object bounced from force plate
  8. Record maximum force (N) shown in logger pro
  9. Record the time for package to drop the last to meters from video
  10. Repeat steps 2 to 9 two times through

During the drops, I noticed that our package fell very fast and the drops were accurate, the package bounced in all three drops. The following data was collected:

Mass of Box (g) Force Accuracy Velocity Time (sec)
Drop 0 A 51.6 132.9 On the force plate 12.6


Drop 0 B 51.6 126.4 On the force plate 10.4


Drop 0 C 51.6 669.9 On the force plate 10.7



Looking at this data table, I wonder why the third time we dropped it, the force was very different than the first two times. The average time it took for our package to fall the last 2 meters was 0.3 seconds. Using LoggerPro, we plotted out the fall of the package.

Drop 0 A

Drop 0 B

Drop 0 C

Our package fell straight and fast all three times. On average, it took 0.3 seconds for the package to drop the last two meters. The package fell on the force plate all three times.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was very successful in hitting the force plate. Our package hit the force plate in all three drops. As a project metric for accuracy, we want our project to land within the 1-meter square around the force plate. The average force on impact was 482.6. As a project metric, our group has decided that for our group’s design, we will try to have more of a “soft landing” we hope the average force of our package will reach a 25% reduction.
Our team has decided that the three most important criteria to design towards are force, accuracy and time. Below, each metric is described, and the goals were determined by data from Drop 0.

  • Force: The force of the drop A and B is around 130 however the force of drop C is around 660. That makes the average of the three drops 482.6. Our group’s goal for drop 1 is to reduce 25% of the average force.
  • Accuracy: The package is dropped on the force all three times. We hope the package will continue hitting the force plate when we do drop 1.
  • Time: It took the package around 0.3 seconds to fall the last 2 meters all three times. My group and I hope for drop 1, it will take the package 0.5 seconds to drop the last to meters.

Our group is now building the first prototype. I hope that the force of the package hitting the force plate will decrease. Our group is thinking of adding a parachute to our package, we think it will increase the friction as the package falls.

Project Collisions: Egg Drop

On Monday, January 7, I began Project Collisions with an egg drop. This design challenge was to drop a raw egg from a height of 5 meters without breaking it. A material list with items to purchase was provided. My first design includes 3 balloons, 2 A4 paper,9 army men and 100 cm of string. That design costs ¥600.

My design

Then, working in a group, we decided to change one of the balloons and A piece of A4 paper to newspaper. In our group design, we wrapped a piece of A4 paper around our egg. Than, we wrapped it between the two balloons with two pieces of newspaper. And secured it with string. Our group design coasts ¥600.

Group design

As the egg was dropping, I through the egg wouldn’t crack, but the egg hit the corner of the table and cracked. Next time, I would Add a parachute to our design to slow the egg when it’s falling, and wrap the newspaper tighter.

Through this project, I hope to improve my skills as a thinker and a collaborator.

The Silver Bracelet



Iris is gone. I stormed into my room and slammed the door behind me. She is taken away from us, to that so called “orphanage” where she will be “safe”. But we all knew better. Anger and sadness crashed into me. I grabbed my backpack and ran into the rain, determined to find my sister.


I should’ve listened to Mia, and never looked out the window. Now I’m alone in the dark, listening to the wheels of the governments car moving farther and farther away from my home.

My Initial design

Jocelyn’s initial design


Volume 62.5 meters cubed

Final design

Our group needs 2 to 4 sleeping spaces. We have that in our Final design. Two people can sleep on the bed and another two can sleep on the pull-out couch. Jocelyn and I need a couch, we have that in our design. The fridge is under the counter in the kitchen. We also have the door from outside to the living room that Josie needs.








This floor plan that my group and I created is to scale because in tinker cad, the dimensions we created are 150 mm by 150 mm. Our scale is one meter= 30 mm. The area of this square is 25 meters. The width of the door is 25mm. That is about 0.8 meters. As a collaborator, I felt comfortable sharing your ideas. Also, I encourage other to shear their ideas. One thing that I noticed our group did well when working together was encouraging each other to shear ideas. One challenge that we had when working together is Josie isn’t here for most of the time. My job in this project was to help build the floor plan in tinkered and help my group come up with the final design.

Growing & Shrinking Eggs

My design is repeatable by another person because I have a clear procedure. I realised that I collected data on the size (height and width) and the mass of the two eggs before and after placed in water and corn syrup. This might have been an issue in my data collection because the mass of the two eggs before putting in water and corn syrup is different. An improvement that I would make if doing this investigation again is to record how the size (height and width) and the mass of the two eggs changed after placed into water and corn syrup.

Notice and Wonders   Data Table and procedure   Initial Model   Final Model

When I first watched the phenomenon, I had no idea how it happened. My evidence indicated that the size and mass of the egg placed in water increased while the size and mass of the egg placed in corn syrup decreased. The size and weight of the eggs placed in water and corn syrup for one day is very similar to the size and weight of the eggs placed in water and corn syrup for three days. Now, I believe that there are small holes in the membrane of an egg that allows smaller particles like water to pass through. However bigger particles like sugar in corn syrup cannot pass through the membrane. Matter is always moving. The water particles tries to reach a point were the concentration of particles is balanced. (when one particle goes in another one comes out).

Material moves in or out of a cell by passing through the membrane. This movement of matter is based upon the concentration of particles.(when the particles tries to find a balanced point ). My evidence that supports this is the mass of the egg placed in water increased by 9.15 grams while the mass of the egg placed in corn syrup decreased by 20.64 grams.

Wenyu River Field Study – Data Collection 3


Site 1

Site 2

I noticed that as the weather gets colder the number of species, the number of bugs and their activity rate decreases. Today my group and I didn’t find any bugs or insects in our quadrant, however, we found a dead ant near quadrant 1. I wonder if the number of bugs and insects will increase during spring when it gets warmer.
