Physics Workshop, Puerto Varas, 11/20/2023
Storyboard 
FOURTH MEETING OF THE SLEP SCIENCES NETWORK
November 20, 3:00 PM - 5:30 PM
Pedro Aguirre Cerda High School, Puerto Varas
We will demonstrate how to simplify the understanding of complex physics through the use of models and analogies with Legos.
This method will be presented in the context of radiation and heat transport, with the aim of comprehending various mechanisms and their applicability.
These concepts will be applied practically to broader topics such as climate change, as well as everyday situations like the design and improvement of heating systems in real homes.
Prerequisites:
• Common sense and observational skills
• Basic knowledge of construction games like Legos
• Competence in interpreting graphs

Demo model

To discuss the house's irradiation, a simple paper model was created, assembled by interlocking its parts without the use of glue.
The walls are cut from a sheet as shown below:
Meanwhile, the roof is obtained from a sheet like this:
To assemble it, fold the central module (the longest one) and close its ends. Then, fold both side modules and attach them to the central module, surrounding the unnumbered wall of the central module. Finally, attach the roof, resulting in the following configuration:
The surfaces are numbered according to the associated surface(s), which can later be individually referenced during the solar insolation analysis to assess direct, indirect, and total radiation they receive. The orientation of the house has been optimized to enhance aerodynamics and reduce heat loss due to wind, especially in the northeast direction (approximately 45°). To determine the model's orientation, you can identify wall 9, which corresponds to the living room, and consider that it has windows that face directly northeast. The view corresponds to looking in the direction of Punta Curiñanco, to the northwest of Valdivia.

The event was organized by the Ministry of Education and is part of the series of workshops of the "Encounters of Science Teachers from the Llanquihue Local Service." Here, you can see a banner from the event:
