Here is my scale model of Layers of the Earth.
Option 1 Answers
A) When Im in the green zone, it feels like I am very proud of myself, and I’m greatly influenced by positivity. I can see that I can start a lot of good habits for myself, and it gets me to keep staying in the green zone. I act positive around other people and, I try not to influence them in a negative way.
B) I set a time limit for my use of technology, so I don’t use it too much. When I use it too much, I usually get mad at the people who remind me to stop using it, and that greatly affects my mental health. I try to keep myself to use technology of what I need to do, such as going to online school, and complete my following assignments before the deadline. When I get a little distracted of the things out of school, right away I remember to get back on track and put my distractions away until I complete all my assignments today. Parents, and Teachers help me by reminding me that I have to make a schedule everyday of what I need to do for school. That gets me more on track and more focused, and they support me so that keeps me in the green zone.
C) Sometimes, I get distracted a lot from time to time, and as the day goes by I stress out on what I have not done today or whats on my schedule. It makes me move to the Yellow Zone, and I sometimes get mad in front of my parents, which influences them in a negative way. It’s hard to bounce back on school assignments when I’m on social media or your gaming. Usually I sleep late every school day, and I wake up earlier in the morning and I don’t get enough sleep. Which makes me do school assignments later in the day.
D) I feel like I always can bounce back on my school assignments and return to the green zone, but I keep letting myself get distracted all the time, and later I stress out about the work I haven’t done yet, and I worry about the deadlines. If I’m in the Yellow Zone, its easy for me to move to the Red Zone where I get super mad. I usually stick with myself being in the Yellow Zone for the whole day forward.
E) I usually go to the Red zone to vent, then I go to a room all by myself and I take a break from being around other people. I go on my computer and watch YouTube videos, and play video games for a bit to calm myself down, and think what really made me angry. I then talk to my parents or close friends of what happened with me being very angry, because I really want to share what happened. Then shortly, go back to the green zone.
When I was at home testing, I overcame that I had to find the materials, cut them, and find a box to drop it on. The most difficult challenge was that I had to test the drop in a public building with people around. I just had to ignore them and film the whole drop like normal. Before this project, I used to think that only delivering products are only using trucks, trains, ships, and planes. Now I think that drones are the new technology of dropping packages and landing safely from 10m. For example, we design a variable for our parachute to drop a box from 10m. Looking back on Project Collision I learned on how to overcome my fears and challenges I have never done before, such as when I’m not in school, or I’m not really in touch with my team, and having trouble finding a spot to test on. One area of data that supported my thinking was the velocity, and the average. I used those to support my evidence and reasoning.
The coronavirus is still a danger to the world, I can’t go outside much now. That means I have to stay home and test. Our team, the Pangaroos our designing a parachute to deliver our package the portable chargers. My research question is “What material decreases velocity to the maximum when used in a parachute canopy?”
These are the 3 variables that I used to test. My materials are Thin Plastic, Yellow Paper, and a Tablecloth. The paper and the thin plastic did not meet the canopy dimensions, so I cut some parts going beyond the edge of the required dimensions and taped them together. Not only did that construct my paper and plastic material but it also gave those both parachutes more thickness so it can have more air resistance when it falls.
The tables shows that the accuracy had a range from 1.2-4.5m. The criteria has to have no bounces, 1 soft landing, the landing distance has to be at least 2m away from the target, and the velocity speed must be on average of 5.12m/s. All the drops had no bounces so that all met that criteria. At least 4 drops have met the criteria of an accurate landing, and 5 drops did not. When I did my first drops on all the variables, it land 2m closer to the target. The variable that was the most accurate and that has met the criteria for an accurate landing was the Paper material. The criteria for velocity was all met below 5.12m/s. The one with the best velocity was the light plastic with an average of 2.9m/s currently holding the best record of slowest fall in it’s third drop falling 2.4m/s! That’s crazy!
To determine which is the best variable material to test with, let’s start with the velocity. The velocity for the Project has one objective, is to decrease as much as it can to make a slow fall to safely deliver the package. My best bet for that variable will be the light plastic, since it holds a best record for the slowest fall and has the best average of 2.9m/s. How the variable has the slowest velocity fall or the best decrease in velocity is because the material the thin plastic is light and can fall more slowly, it also carries more air resistance as it falls. The lightest material always falls down the last. In fact, gravity pulls down all objects to the same force, but the lightest flat objects are the last to fall because it can create an opposite force called air resistance to decrease the velocity according to Newtons 3rd Law. When it comes to accuracy, paper is the closest to that bullseye! When I tested the parachutes, I did that inside a building, Therefore blocking wind to blow it away from the target. That is kind of what made the parachutes fall a little closer every time. Paper is the most delicate material out of the three, and can easily move around a lot during fall. That can be taken as an advantage to accuracy since it can move closer and closer to the target just before it falls down, and there was no wind to blow it away, Therefore making it the best variable for accuracy.
And now, the conclusion to this Blog Post! I have to choose the best Variable for my Material! Does Accuracy matter, or Velocity? I would say that velocity matters, because as long as the package lands safely and slowly, its fine rather than getting blown away and not accurately landing in the right spot because you can find it easily, and even chase it down while falling, plus it cant be blown that far because the parachute and the package contain some mass so it cant be blown far. Anyways since the Velocity matters, the best variable for that is the light thin plastic. Since the plastic is light, as it drops, it creates more air resistance and less gravitational pulls.
Therefore, I now recommend the Light Thin Plastic to use for material since it can decrease velocity to the maximum!

The coronavirus arc is still happening, people struggling against the virus. I happen to be at home testing my prototype by dropping it with my parachute. My team Pangaroos are designing a parachute with dropping our package “portable chargers”. We will be dropping it from 10 meters, it has to have a soft landing, the velocity has to fall 2m per second, and it has to be at least 50cm away from the target. My research question is “What material can decrease velocity to the maximum?”.
The data collection procedure will be:
Here is my Data Table
My design build:
Canopy of parachute diameter: 75cm
Cotton string length: 30cm
Package Box dimensions: 20cm (length of box)
This is where I will test my drop. (Location might change)
I might set up a ladder and drop the package from 2m.
The variables and materials will stay the same. My constraints might change since I have to use another material.

Our Team, the “Pangaroos”, are delivering a package with a drone. Our package is delivering Portable Chargers. Our team already did the Drop 0, and now we’ve designed our sketch for the parachute of our package. Our criteria is the package has to have a soft landing, no bounces, the landing accuracy has to be at least 2m away from the origin of the landing, and the velocity of the falling package must decrease. My research question is “What Material Used in the Parachute Canopy Decreases the Velocity of the Maximum?”.
My prediction is that I will be using Plastic Tablecloth for the material of the Parachute. I and Anya think that is the best design. The material is very light and will cause the parachute to fall slower and decrease velocity as it keeps falling. When a Parachute is released, the weight pulls down on the strings. The large surface area of the parachute material causes the parachute to fall slower, and increase drag. https://www.scienceworld.ca/resource/parachute-design-and-drop/
Reflection of My Client App.
In the beginning of this project, I used to think that making an app with lists is going to take too much time, and it’s very complicated. Now I think that I can code multiple lists to create a quiz for my friend. It’s easier to do.
The problem is my friend Alexander does not know a lot of memes, and I know way more memes than he does. So, he wants to know a lot of memes on the internet like I do.
That is the reason why I created an app to test his skills of his knowledge of memes. He can learn the new memes from the app that he is not familiar with. After he uses the app, he will know more about the memes on the internet, and it will solve his problems.
I chose to design originally to be a Meme creator app where he could have fun making his own creations, but that didn’t really work out, and that took way too much time to do, and it’s going to have a lot of complicated coding to do. I wrote my app proposal differently about my app making memes, and my tablet wireframes are different than my app is now. So instead I’ve come up with making a Meme quiz. I used a lot of screens for this quiz, because I felt like it’s easier to do. I did not create a global score that works at all when transferring from screen to screen, so Instead I created Alternate screens in case that showed points. It took time, but eventually I did it. I didn’t use multiple choice answers for the quiz because that would make it really easy so I made the client use text box for challenging stuff.
Why I changed the app from Making Memes, to Meme quiz is because Firstly, making memes takes a lot of time to make and I probably wont make the deadline for the app. Secondly, making a quiz is way much easier to do and I can make the deadline. Thirdly, my Client Alexander will learn from the memes he got wrong. So, after he plays the quiz, he will know more memes than before. So, technically this app is educational. Here are my design blocks for the screens in my app.
The quality of the app works mostly well, though there are rarely times where the app might crash due to a lot of screens in my app. So, if you don’t spam or press the buttons fast, the app should be fine. The functioning of this app just jumps from screen to screen after each question. There are 12 screens in total.
The strength of this project is that it’s a quiz, it functions well, and you can play again and again anytime you want. The weaknesses are that there are only 8 questions including the alternate ones, the quality is not that perfect, and there is no global score to begin with.

Device: o Phone o Tablet
Describe the problem your client is having/experiencing (3-4 sentences):
His life is very boring, he wants to make some funny stuff. He does not have an app that he can make memes. So, he is trying to find an app that he can make very funny and entertaining stuff. He is finding an app that is creative, so he won’t get bored at all. He expects it that it can work without Wi-Fi, because he can take it on the go and annoy the heck out of people.
Describe your proposed app (3-4 sentences):
My app is a Meme maker app. You can make memes, and make videos, with some CAPTIONS!!! Pretty simple app with 4 screens. 1 screen is the Menu, which has 3 buttons that will take you to the Take a picture meme. The screen has a toolbar with pictures to choose from, and once you choose that picture, you can add stickers, and captions. You can submit and save that meme as well. There is also video meme maker, you can choose a video from the toolbar, and add captions or stickers. Submit it, and it will save the video. You can also change the music of the meme video from the selection from the toolbar.
Describe HOW this app will solve your client’s problem (3-4 sentences):
It will cure the boredom of my client. It will entertain the creativity of my client and will make the client laugh the memes provided and the memes he made. Some of the meme music is also very EPIC, so it will be an offline playlist of my EPIC music that my client will listen to without internet, and use for making his meme. He will access all the app without internet.
