"People cry not because they are weak, but it's because they were strong for too long"

Wenyu River Field Study-Data Collection

On March 7th, we once again have visited our familiar Wenyu River during the springtime. Due to my absence to the previous observance of the water quality, and I did not record the data on my notebook, today I was disappointed about what we found out about the facts of the river. With the support of my teammates, I was able to record all the missing “files” into their notebook. And the end result was a massive decrease in the dissolved oxygen as shown below.

As a wrap-up, I can conclude that there was a massive amount of trash being dumped into the river, and the devices were not “up-to-date” as we have abandoned them for so long. Despite the standards of “proper-usage” of the types of equipment we’ve been given, our observance was expanded to the nearby soil that may disturb the site. Which it turned out it did, so I knew the dropping of the soil’s temperature from 17 to 13 degrees also has affected the lives in the river. And the second when something dropped in the river, we saw a dead fish. It proved to us that something must have been done by outside foreign chemicals. These substances are greatly depleting the oxygen levels in the water.

Humans of ISB-Brief Overview

Humans of ISB was a descended idea from the book “Humans of New York”. It showed many pictures of photography of random citizens that does everyday life in New York. We got inspired and created a similar design of randomly selecting people from ISB. The idea of this event is to find someone who we think means a lot to us, and do a short interview to get to know them a little bit more. Throughout this process, we came up with many questions. However, we only finalized two questions. They are, “What is your happiest moment in life” and “What are you worrying about your job right now?”

In the end, we have to create a charcoal model, a quote, a few photographs and a video of the interview. We are doing this mainly because it gives us an opportunity to understand how to capture the most important details of what everyone is doing at ISB. I took a very long time just to find someone who I can really interview and get a satisfactory answer. At first, I thought just simply finding someone I know will be able to finish my project. Turns out, even wasting thirty minutes of time was still not enough for me to pay the penalty price to find someone to interview.

The Ice Cream Challenge

Okay, so writing this makes me feel totally out of my mind. But today, we did a really interesting activity along with the entire FA 7. It’s a game involving building communities. It’s called the ice cream challenge because our groups were sorted based on our favorite ice cream flavors. It was a pain for the strawberry group, which I was in, to hire a lot of employees since our team was very disorganized and had only 5 people. But because the strawberry group was at the highest level, we were able to see the different groups and their ideas. I was able to create many things that the vanilla group was creating by simply negotiating with Aidan.

One Day 2019-Mahjong By: Grade 7 Brandon Zhang

My goal is to learn how to fluently play Mahjong. I successfully achieved that. In the process of learning this game, along with Chinese Chess and “five-in-a-row”, I’ve learned a lot just by playing the game along with some friends. The procedure is similar to chess and “five-in-a-row.” It’s very confusing and difficult to match the same cards or consecutive cards, for that matter. To be able to select the “amateur” and “professional” groups, we determined the groups by a match play, within the winning rounds of Chinese Chess and “five-in-a-row”. I played for two rounds, the first with the professionals and the second with the amateur. I’ve won the third round with the help of Yao, and the fourth with the help of Aaron. To my surprise, the new “Mahjong learners” pretty much excelled the second Ryan Wong taught us. It turned out that Mahjong is apparently a very fun game, not just for gambling.

Rules and Guidelines

The rules of Mahjong is simple once you get the concept, a little Chinese Poker-style is when you have to match two of the same brick (same card type with the same number of that type). That’s called a peng. You’ll need to do that four times, or have four groups of three of the same brick to complete what’s known as a “full set”. You must say “ting” at that time, identical to UNO. With a consecutive four sets of three, (6,7,8 etc.) the cards are received through a process called “chi” or basically it means eat. This procedure is unique because before a “ting” was announced, you can only “eat” the cards to your left. You have to leave yourself with fourteen cards before you can have a “win-win”. The last two cards must be identical to each other, without the three special cards, which are “zhong, fa and white dragon.” If, during “Taiwan” round where the game is significantly harder, the “zhong, fa and white dragon” can help you gain a set. That set gains you a point (only if you want to gamble though). Below are procedures of a round of Chess and a round of Mahjong.

Drop Test #2

Project Phase: Drop 0 – Data Analysis & Blog Post Futures Academy 7

January 21, 2019

Our design has concluded our drop experiment. The final layout was quite satisfying. Due to a completely withdraw from the idea of using a trash bag, we decided to use an inflatable plastic bag that rescinds the force of gravity. The reason why I’m trying to inflate the force upon the dropping action is that whenever we drop the box straight down, the more materials, the heavier. Although nearly everytime we aim and hit the target straight, regardless of the bounces, any materials that don’t let air in can cause the molecules on it to stick to the surface of the box. Which is why on the last drop with the trash bag, the strings got stuck onto the box. The results didn’t even motivate us to fix our design, we were forced by the outcome that the parachute and the landing components. So then my group member, Paul, has come up with a better idea. Even though Max and I took a heck of a long time to tape on the already tied ropes to an inflatable plastic bag that expands upon dropping. Turns out, with one drop, it met all of our requirements, the box landed accurately, the force upon impact didn’t exceed 343 newtons. And even with the drop not being angled correctly, the box flew to the ground at only 4.8 m/s.

Drop Test 0

Main Driving Question: How can our group deliver a well-qualitative machine that efficiently delivers coffee?

General Driving Question: How do we create/design a reliable delivery system for our customers to safely use?

1. Purpose

On Tuesday, January 15, the first drop of each group’s “package” will take place. The purpose of our drop is to gather evidence of “baseline data” in order to compare with the other results. Many groups have concluded that in order to complete a “soft landing”, they most likely need to use a parachute to stabilize the effect, especially when it comes to the impact upon landing on the base because the data is recorded in Logger Pro.

2. Market Research

Our idea is to deliver coffee to those who need it regularly, we have done multiples of surveys and interviews the day we began the investigation of how to efficiently bring coffee to the remotes. It’s a great way we developed to save time. The purpose of this is to determine:

  1. Do people want what we are thinking about what to deliver?
  2. For our potential products, how will we narrow (or expand) the items that will be delivered? For example, will we deliver coffee mugs and insulators to keep it warm at the same time?

3. Package Expectations

This is where your understanding of your product (what you will deliver) and research comes in.

  • ●  We are planning to cooperate with Starbucks so they can sponsor us the product that is essential to us.
  • ●  Our dimensions cannot exceed 2*5*4 cm, or best is to stay lower than 30cubic cm.
  • ●  Our mass of the final product is unsure, but the impact cannot exceed 443 newtons.
  • ●  A design sketch showing the dimensions with the interior items is required.

4. Drop Procedure

As a scientist, you understand the importance of making sure that tests are conducted in the same manner each time. As an engineer, this is extremely important. The quality of your design is based upon the data that you collect and how you respond to it in order to meet your metrics/criteria. Procedure must include

  • ●  How the package will be dropped.
  • ●  Data table that indicates an amount of time it takes for the package to drop.

5. Deliverables

  1. Survey & Results of market research
  2. “Package” that represents your product (no design applied)
  3. Procedure to drop package and data table to collect data
  4. Design Sketch that shows the interior of the package with the deliverable product

Design and Project Layout

In Project Collisions, I am creating a system to deliver coffee by drones. The drone will release the package from a height of 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 2 cm by 5 cm by 3 cm was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold 1 bottle. Inside, items are organized 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.

Drops  Force (n)  Velocity(MPS)  Drop Constraints  
0  441.63  2.83  Keeping Warm (Coffee), Accuracy, No Spillage  
0  31.7  2.83  Keeping Warm (Coffee), Accuracy, No Spillage  
0  667.3  2.83  Keeping Warm (Coffee), Accuracy, No Spillage  
3       
4       
5       

During the drops, I noticed that the box hit the target pretty accurate, and the drops were “successful”. The following data was collected:

THE DATA TABLE WHICH WAS RECORDED DURING THE DROP

                                                        

The average time it took for our package to fall the 5 meters was U<amount of time in seconds>. Using LoggerPro, we plotted out the fall of the package.

Description of the falling action of our items

The box hit the target hard and fast on the first two drops. The first one had a landing force of 441 newtons upon impact, the second one had a landing force of 243 newtons upon impact. The graphs above label how far the box bounced away from our projected target once it hits earth.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was successful at hitting the “target”. This is my accuracy metric! A screenshot with our data is below for the information on the impact. As a project metric for accuracy, we want our project to hit the target (without backspin) and not bounce too high or too far from the base. The distance we are trying to rescind is more than 20 cm from the outside boundaries from the drop zone.

My procedure of designing the box

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. Check that the box is completely sealed, and the package does not leak. 

2. Make sure the parachute is hooked onto the package and the parachute is stable. 

3. Make sure the height is right and the parachute is spread and not tangled onto the package.  

4. Connect the logger pro device to the computer and get ready to start the timer. 

5. Make sure the drop zone is clear of humans and there are no obstacles nor obstructions

6. Start the drop and start the timer to record 

7.Drop the package and make sure the force sensor records the package drop 

8. Take out the product and check the quality of it 

9. Record the data of the device and start designing the next drop based on the data. 

10. Weigh our coffee mug and space it within the cup holder before the drop test is examined 

11. Repeat step 1-10 at least three times

As a project metric, our group has decided to decrease the impact and the effect on the object (coffee). And doing so request us to make a piece of landing equipment, it may not be completely exquisite, but it will give an asymptote landing path which will obtain our goal of reduction 50% of the force upon impact.

Summary: Project Metrics

Our team has decided that the three most important criteria to design towards are accuracy, temperature, and free spillage. Below, each metric is described and the goals were determined by data from Drop 0.

  • Metric 1: Accuracy of landing: 10-30 centimeters away from the center
  • Metric 2:  Temp 0.5-1
  • Metric 3: Coffee no spillage

Our group is now building the first prototype. I hope that we at least have a few methods to land the box safely and accurately with a parachuteand at the same timedeliver the product safely with little or no disturbance of which the quality won’t decrease.

A new technology-Minecraft

My story talks about the struggle two students in AlasKansas (Canada) with their childhood of growing up in famine. After being inspired by the new technology in Minecraft, the imaginary character named Lasik (which Elon was desperate to help) wanted to set humanity on Mars. Out of everything I did, I like the exhibition the most because that’s when you can present to everyone your actual work.

BZhang G7 U2 Stories of Future Driving Question Reflection

What is inside such liquid like Karo Syrup?

The picture below represents my observations of the egg that either grows or shrinks in special liquids. Based on my team’s observations, the first egg that was in the vinegar was a little bit heavier than the second egg in the vinegar. And due to substances in the corn syrup that will get caught in some pores on top of the egg, it will eventually get pressured and shrink its size. The displacement of the syrup was about 100 ml, and the diameter after being soaked in corn syrup was 13cm. Vice versa, if the egg is soaked in any hydro-oxide particles (like water), then air is let out of the egg, causing it to expand. Except for the data in the pictures shown down below, the displacement of water was a little less, about fifty milliliters along with a 20cm egg in diameter. In addition to those two experiments, there’s a security check as the initial step. That was using vinegar to de-shell the eggs, a displacement of 80ml of acidic vinegar did something quite interesting. Instead of interacting with the holes on the egg, it physically “eat away” the eggshell, giving it an ugly look and a smell like chocolate exposed in the sun for a month. I used to believe the egg did not interact so much with the vinegar, but it turns out that the difference between the acids and the alkalines were quite obvious. Inconsiderate that the egg does not change its mass due to the vinegar. In fact, the egg displaced a whole lot of vinegar, which it moved around with the acid too!

The greatest Soviet apartment

Our concept is based on Sola’s idea of creating a small but special toilet while making the base wide and spacious. The living room is separated by a divider which has the kitchen on the near side, and an eight square meter bedroom on the far side. A toilet was created using a special function, and it was enlarged to fit on different altitude so that not all of the bathroom needs to be cramped in a small space.
