Description :
With innovative minds, the “Green Sparks” team engineered a house machete that serves as a compelling model of an energy-efficient dwelling. Their design probably incorporates clever solutions for insulation, lighting, and water conservation, sparking interest in sustainable living.
Hats off to the “Green Sparks”! Your ingenuity in translating energy efficiency into a tangible and thought-provoking house machete is truly impressive. You’ve ignited our imagination with your creative approach. Brilliant!
Our class consists of 25 5th grade students, 12 of whom are boys and 13 are girls. We all worked together on a common project on the topic of Energy. We divided into groups and built models of an energy building. After completing the project, we all presented our models, having received specific criteria, at an open event in the presence of parents/guardians and a jury of teachers. It was decided that the most complete model is the one of which we are sending you the video.
Initially, we all discussed together in class what energy means, where it comes from and how we use it in our everyday lives. We talked about renewable and non-renewable energy sources and observed how its use affects the environment and our lives.
We recorded ideas on the board and through questions and examples, we were led to think about what an energy “smart” building could be: with solar panels, thermal insulation, water and electricity saving systems, etc.
Then, we were divided into groups and each group was tasked with building a model of an energy building. During the construction, each child had a specific role: some took charge of the design, others of collecting materials (recyclable where possible), while others were responsible for the construction or presentation.
The work was accompanied by a collaborative spirit, shared responsibilities and creativity. We recorded the steps of the work on a worksheet and each group wrote a short description of their project, which they presented on the day of the event.
The open event was a special moment for all of us. We had the opportunity to present our projects to parents, guardians and teachers, to explain the function of our models and to talk about the importance of energy in our lives.
The most complete model – the one we present in the attached video – stood out because it combined originality, construction accuracy, and a comprehensive presentation of energy design.
This project helped us to better understand the concept of energy, but also to collaborate with responsibility, respect and imagination!”

Congratulation dear Green Sparks! Looking towards the South is always a good idea! Also special trees that drop their leaves in the winter or don't drop their leaves in the right angles are such a great trick! Collecting rainwater is an ancient and classic way to save water and be more indepent! It's hard to mention all your amazing hacks to save energy! Your house is so green, it probably has its own tiny rainbows that sparkle! 🌈🏠
