Design Challenge

Full STEAM Ahead At Carmel School!
STEAM (Science, Technology, Engineering, Arts and Mathematics) are a part of our IB Approaches to Learning in the classroom as well as blended in transdisciplinary themes — encouraging creative thinking and problem solving.
From the use of AI-powered technologies, to genetic engineering and modification, to technologies developed to combat climate change, Grades 6 to 10 are looking at Innovations that have changed life. Leading up to the three day whole-school Design Challenge, classes from across the disciplines are looking at technological innovations that have shaped our world.
The Design Challenge
Design Challenge 2025
This year, the Elsa High School section Design Challenge put students in a simulated lunar environment. Themed 'Battle Blocks' students in groups were tasked with designing, building, coding, and branding their own Battle Block bots. Their Lego Technic based vehicles were then stress tested in different scenarios to see who would be crowned champion.

WHAT WERE YOUR FIRST REACTIONS TO THE DESIGN CHALLENGE BRIEF?
Ahree Grade 6 I initially thought the Design Challenge was going to be very difficult, especially because the task was to build a “battle bot” in 2-3 days. However, once I explored the task more deeply, I could understand that it wouldn’t be too hard, as long as our team worked together. We first decided to research more to further understand our task, so we could complete it while knowing what we were doing. We then decided to find out which of the roles each of us was best at, so we could all work hard while working well at the same time.
Emily Grade 8 I enjoyed the Design Challenge idea where we made robotic rovers to mine for Helium-3; it was an interesting blend of planetary science and technology. The different activities were also quite exciting, such as the Alliance Quest and the Duel Done, where the robotic rovers competed against each other in 'timed battles'.
Our team devised a strategy for the challenge, going over all of the possibilities for different things, such as what we would need to do if the other team’s robot were larger. What would happen if we added so and so, etc? For our roles, we went through all of our experiences in the past and made a decision that matched our skill sets.

HOW DID YOUR TEAM GO ABOUT STARTING THE INITIAL PROCESS? HOW DID YOU DIVIDE YOUR TEAM’S ROLES?

WHAT WERE SOME OF THE CHALLENGES YOUR TEAM FACED AT THE BEGINNING OF THE WEEK? HOW DID YOU OVERCOME THE CHALLENGES?
Ahree Grade 6 The biggest challenge we faced at the start of the week, and my team will agree, was communication. On the first day, we all yelled over each other and argued, but by the end of the week, we were left with a 'Super Trooper' robot that was fully functional! Although we struggled to share our ideas and to compromise, we managed to consider all of each other's suggestions and fulfil them to the best of our abilities.
Emily Grade 8 One of the challenges we experienced was when our robot didn't function. In spite of that, we overcame the issue by asking an expert for help, changing our motors and putting less weight on our rover. Another challenge was when a few Lego pieces broke, but we managed to save up enough to get replacement pieces.
Shahar Grade 10 At first, our team found the Design Challenge difficult because none of us had experience designing a functioning robot. However, we quickly realized that each person brought different strengths to the group—some specialized in media, others in building or coding—so we decided to divide our roles based on individual skills. This approach helped us stay organized and confident as we began turning our ideas into action.
One of the biggest challenges we faced early on was placing the motor in an unusual position. Initially, we thought this mistake would cost us the project, but through testing and trial, we discovered that the motor’s placement actually improved our robot’s performance. It created a spinning gadget that could clear spaces effectively, which ended up being one of our robot’s standout features. This experience taught us the value of problem-solving and keeping an open mind when things don’t go as planned.
The highlight of the week was when our team, AkivaX (Akiva 5), won first place out of 23 teams with a total of 174 points. We were thrilled that our creativity, teamwork, and perseverance paid off. Looking back, the Design Challenge not only improved our technical and design skills but also strengthened our collaboration and communication as a team.
Felix Grade 9 When we first heard of the Design Challenge brief, it was really exciting because it was unlike anything we had ever done before. This year, we looked to Outer Space and robots to inspire our designs. It was a unique opportunity to explore our creativity while tackling real-world engineering problems. Many of us were eager to step into leadership roles and collaborate with classmates we hadn’t previously worked with, which added an extra layer of enthusiasm.
We began the initial process with an open brainstorming session in which everyone shared their thoughts and ideas. This approach encouraged participation from all members and helped us to build a sense of ownership in the project. A challenge that my group faced was that none of us knew how to code on Scratch programming, so it was particularly difficult to move forward from that. Despite this, a group member was determined to figure it out, and in the end, we placed second overall!

WHAT WAS THE HIGHLIGHT OF THE WEEK?
Ahree Grade 6 The highlight of the week was definitely the mini challenges, where we could earn points and purchase items at the upgrade store to improve our rovers. At the end of this challenge, I had learned not only about the moon but also how crucial it is to communicate with the people around you.
Yeda Grade 9 The design challenge brief was very unexpected. Along with many others, my first guess was that the challenge would be related to rockets, spaceships, or satellites, and I definitely did not expect the battlebots element. I think this design challenge had the most unique and interesting theme out of all of the past ones I have participated in. Once our team had understood the assignment, we divided ourselves into our best-fitting roles, such as engineer, programmer, designer, strategist, and project manager. One of our biggest challenges was that our team did not have a member who was well-versed in designing and engineering a robot to function well. We overcame this challenge by learning from many different teams and taking an idea from each of them. My highlight of the week was on Thursday when each team presented their robots and used the product of three day’s work to compete against each other. In short, I think that this year’s design challenge was one of the most successful out of the four I have participated in.
Emily Grade 8 Our best highlight was definitely seeing the robot come together and our code working the first time — even with all the challenges. Seeing it all come together the first time is very rewarding.

Design Challenge 2024
This year’s design challenge aimed to push the boundaries of students' skills and abilities. While previous challenges focused on speed, the Cableway Challenge emphasized control. Students were presented with a scenario set in a future world where populations were forced into mountainous terrains, relying on aerial transport to meet various needs. With this context, participants were divided into three specialized categories. Despite the technical demands of the challenge, students rose to the occasion, producing exceptional and innovative solutions. This year's challenge proved to be the most successful yet, showcasing the remarkable creativity and problem-solving skills of the students.

Student Reflections
Every year, the design department at Elsa High School organises a unique STEAM challenge for Grades 6-10. This year, from Monday 16 - Wednesday 18 December, Mr. Donnoli and Mr. November prepared a cable-car-themed challenge for us. We were placed in groups of 5-6 people and designed a gondola to achieve one of three objectives: rescue, tourism, construction. This was one of the most technical and difficult design challenges I have participated in.
We used an Arduino board for electrical tasks, motors and controllers for moving our LEGO Technic chassis, along with mixed materials for branding and aesthetics.
Throughout these challenges, we learned how to logically solve problems, collaborate with different people, and acknowledge the importance of the perspectives that each person provides. This year, there was much less instruction provided, which prompted students to be the ones asking for help and to think critically.
Although the event was challenging at times, it was very enjoyable, and everyone learned something--regardless of their contribution.
Ayla Grade 9

This year we were challenged to build gondolas, based on one of three categories: Rescue, Tourism or Construction. My team and I were part of the Tourism team, and we named our gondola the Cloud Cruiser. It imitated the design of the Peak Tram, as a more effective and modern mode of transportation which still embodied Hong Kong’s traditional roots. We faced our biggest hurdle with our motor, which was faulty to work in its initial stages. With some help from the teachers, my team and I were able to fix it. All in all, it was an exciting experience, which geared us up for the end of term.

Design Challenge 2023
Elsa High Section’s annual Design Challenge took place in February, hand-in-hand with the Elementary and Preschool STEAM activities. Elsa students were tasked with designing, making, and pitching an airboat capable of navigating terrain to simulate delivery of rescue supplies. Unique to this year's challenge was access to First-Person-View (FPV) wireless cameras and head-worn displays, as well as the specification that their designs must use upcycled packaging materials as hull components. This technologically forward and eco-friendly approach encouraged innovative engineering and promoted sustainability.
Pre-K to Grade 5 participated in a challenge centered around disaster relief operations, in line with their High School peers. This engaging activity empowered students to showcase their creativity and problem-solving skills.
Situation
Step into the shoes of real-life heroes in this Design Challenge centered around disaster relief operations! A devastating flood has left an entire community stranded, with no means of transportation. Your task is to design and construct an airboat capable of navigating through floodwaters, debris-filled streets, and reaching isolated areas to provide essential supplies and rescue stranded individuals. Are you ready to make a difference and be part of a life- saving mission?
Challenge
Get ready to engineer innovative airboats that will restore hope and save lives in times of disaster! In this challenge, you will create a First Person View (FPV) remote control airboat using only reused packaging materials as the building material. This eco-friendly approach not only demonstrates your engineering skills but also promotes sustainability by repurposing materials.
Your airboat will be capable of navigating a treacherous obstacle course, made up of land and water! It will also be instrumental in delivering aid packages, rescuing stranded individuals, and ensuring their safe passage to security. Let your creativity and resourcefulness shine as you embark on this mission of compassion and environmental responsibility!

Student Reflections:
Peter, Grade 9: Coming into this year's Design Challenge, I did not know what to expect. When it was revealed that we were meant to build an Airboat, I was surprised. I expected it to be difficult: how were we going to be able to build a vehicle that goes both on water and on land and can transition between them? Thankfully, we were provided with a starting kit, which we could then build upon.
My Team and I divided into two initial roles, one group working on the Product Pitch and one team working on the Airboat. At the start, when we just had to build the kit, we split off into teams. However on the second day we all worked on building the airboat and contributing all of our ideas to create the team's Airboat. Some challenges with my team specifically was the weight of the Airboat. Our Airboat has an elongated front and pontoons on the side, like a catamaran. However, due to the use of lots of material, our Airboat was significantly heavier than other team's airboats. We changed and modified our airboat to have a slicker bottom and removed unnecessary weight from the front of the boat to counteract this conundrum.
My Highlight of the week so far has been seeing our work culminate into a final product. Seeing our airboat being able to slip and slide on the track and float on water has been amazing. With all projects, seeing your vision finally come to life is an amazing feeling.
Lili, Grade 10: An atmosphere of immense excitement and anticipation led up to the Design Challenge, and it only continued throughout the whole experience! My initial reaction to the Design Challenge brief was nervousness but excitement as I’d never heard of what we were making or its incredible purposes. The challenge was to create an airboat that could skim above the water and pass through debris and other obstacles. We were given a starter kit that gave us a base for our design, but the details and design were entirely designed by the students.
We faced several challenges throughout the creation process, including our boat's design being too heavy or our presentation and pitch not being detailed enough. Our group took time to communicate and adequately assign roles to solve all of our problems, which helped us create a boat that we were proud of and brought us all closer together as a team. My personal highlight of the week was the first test of our boat, as the suspense and slight worry only made the boat's success in being able to move all the more exciting.
Trisha, Grade 9: This is the first time I’ve ever taken part in a Design Challenge. I was quite excited to collaborate with students across grades to learn about each other's strengths and interests. I think I was anticipating the end of the challenge, just to see how well we could do in the challenge. Through discussing we figured out everyone’s strengths. I researched about the boat, and made a couple of sketches with my teammate, and we gave them to the others to build. Overall, we had a great balance between the building, researching and presenting part of the project. When the final Airboat was brought inside the auditorium, freshly coated in spray paint, I felt nothing but pride. My team had really pulled it off!

Cedric, Grade 9: I was really excited and eager to participate in the challenge and push myself and think outside of the box. The challenges we faced in the beginning was how we should make our airboat since everyone had their unique ideas and we were contemplating about which would be the best for us with the limited resources and time we have. The highlight of the week for me was the second day of our build and testing day. I was really excited and nervous about testing our airboat for the first time but it turned out way better than we expected and even others! We were the fastest on track and the only one that managed to get over the pond.

Design Challenge 2022
The Elsa High School Design Challenge began on Thursday 15 December. Students in the MYP were joined by our Grade 11s - forming 21 design teams in total - to complete this year’s challenge. Teams are organised by School Houses to heighten the stakes!
The Situation: In the near future, we will be combining the technology of old and new to develop efficient and autonomous goods transport systems. Healthcare and medical emergencies are prioritised when it comes to rapid response in urban areas, which is why we are calling on you for submissions of drone pod designs that can be used on a zipline network throughout Hong Kong. It is critical that pharmaceutical products and medical devices are moved safely and rapidly to the places and people that need them most. Help us create the future.
The Goal: Create a high-speed propeller propulsion transport pod that can rapidly move along a zipline and deliver a payload.
Peter, Grade 8: This was my first time ever doing the Design Challenge, I didn't know what to expect other than the fact that it was a challenge. We were tasked with creating a "Zipline Pod" capable of transporting medical supplies quickly and efficiently.
The highlight on Day 1 for me was collecting the materials and starting to build the "Zipline Pod"; my team and I put our plans into action and it was fun to see how everything fitted together. During the build process there were multiple hurdles we had to overcome, sometimes we did not have enough of one material or we could not decide on what would work best for our Zipline Pod, however after certain deliberation and working together to find a new comprisable solution we were able to work around our struggles.
Now after the Design Challenge is over, it was an enjoyable experience and it was great to plan, build and put our creation into action. Thank you to Mr. Donnoli and supervising staff for making it happen!
Lev, Grade 8: This was my first year of the design challenge, so I did not know what to expect. This year's challenge was to create a motor-driven zipline carrier, capable of carrying 50g. It is supposed to be built to transport the payload efficiently both up and downhill along a zipline.
My highlight on the first day was making the model. We made drawings and designs, and then we made them come to life, and for me, this was quite fun. The biggest challenge for our team to overcome was the weight of our pod. Testing our model was really exciting, but sadly I won’t be here for the races.

Talia, Grade 8: The Design Challenge this year was really fun and challenging. I really enjoyed working with my team! I think it was very interesting to make technology that could carry important and potentially life saving equipment and medicines around the city. We definitely achieved our goal which was to make a perfectly balanced zipline carrier that could go fast with a valuable load inside.
Some highlights were doing the presentation, finishing the actual product and doing the race against other teams. At one point our motor had broken and we lost our mini challenge cards; we had lost any hope we might win. Then we decided it wouldn’t help just sitting around so we got up and worked hard and fixed our product and we did well in the races. I thought it was a great opportunity for our whole class and I really enjoyed working with my team and I learnt a lot of things along the way!
