Lite Bike

-

For our second unit of Design and Engineering, we had to finish this term by designing a bike that would fit the persona given to us by our teacher. We had to design a bike using empathy. We learned about designing with empathy in our last unit. In this unit, we learned about speed conversions, gear ratios, Newton's laws, energy, derivatives, and we learned a lot about the volume and area of 2D and 3D shapes.  We met virtually with a representative from Divvy to learn about the program that they have in Chicago and how they believe it is helping our communities. We went to a bike shop called Earth Rider to learn more about e-bikes and how they work. I worked with another student to complete this project, here I have attached the link to their blog post. 

Our persona lives in Banff, Canada, and has to travel 3 miles to school every day. They have to travel along winding roads and it is often cold. They have to carry their school books during this ride to and from school. They store their bike in the garage, but there is not a lot of room. For our design, we decided that a lightweight frame would be easier for our persona to use since they are traveling every day. We choose to make the frame a bright color that would be easy to spot from far away. We wanted to add a really big front and backlight. This makes it safer for our persona to travel along winding roads when it is dark out. We believe it would be good to add grippy tires and strong brakes, especially since our persona sometimes travels in icy and snowy weather conditions. Since the weather conditions can be harsh we also decided to add spikes on the pedals so that the user does not slip when they are pedaling. We included quick-release wheels and a foldable frame so that the bike could be stored in small, tight places.

Most of these ideas that we included in our design have already been used in the designs of other bikes. So we came up with heated mitts that would cover the bike grips. This would help our persona when they are traveling in cold and windy conditions. This idea came up after an interviewee said, "Barmits changed winter biking for me."

This project was one of my favorite. It was interesting to design something based on a certain persona. I also had a really fun time creating and designing the 3D model. If I had to do this project differently, I would try to think of more original ideas that could make my bike better for the persona I was given.

Slowly Sloth

Hello! For the first STEAM class of the year, Population, we learned about taxonomy, set theory, quadrilaterals, and biology. To prepare for this class over the summer we read In the Shadow of Man by Jane Goodall.  We also went on our first FE to the Lincoln Park Zoo where we chose the animal we would study for our AP. We then continued to study our animal by visiting the  Field Museum to observe the taxidermy animal we had chosen. For our AP we had to create a project explaining the taxonomy of the animal of choice. I chose Hoffman's two-toed sloth because I think sloths are really interesting. In the project, you will read about Hoffman's two-toed sloth, its habitat, taxonomic categories, and the morphological traits that show the taxonomic categories. You will also learn about set theory and how my animal compares to other animals my classmates have chosen. I hope you enjoy it! CH.

Space Debris Science Conference

Welcome to the third action project for my STEAM class, Frontiers. This class is about exploration. This project connects directly to my second action project, Space Junk . For this action project, I had to create a poster based on a research paper I created this term. I choose my most recent paper on space exploration. In this paper, I choose to focus on space debris and how this affects space exploration. This poster summarizes my research paper.  CH."Space Debris Poster." Google Slides, 2022. I enjoyed completing this poster. I have a great interest in space, so putting together this poster was fun for me. I believed I have managed my time well with this project as I did include the feedback given to me by my teacher.

Coraline's Closet: The How-To Guide

Welcome to my last AP for Endurance. During this class, we learned about different individuals who physically and mentally endured challenges in order to survive or reach a goal. For our AP, we had to create a survival guide or how-to manual on something we see ourselves taking on and challenging ourselves with in the future. I choose to write my how-to guide about starting a clothing brand. I choose this as my topic because it is something I am really passionate about and could possibly see myself doing in the near future. I feel that I would have a lot of challenges if I were to take on this mission. After creating this guide, I can see that with the proper training and support I will excel. I am happy with how this project turned out. I hope that whoever reads this manual can learn something new. This is also my last AP for GCE. I am honored that it was from such a great class and project. Have a safe summer! CH. "Coraline's Closet." Canva logos, 2022. CH. "Surviv
