1.Logo
Each team prepared three logo proposals. During their visit to Warsaw, Poland, the project participants selected one logo from among the submitted proposals. The winning logo was created at Bilingual Primary School No. 1 in Warsaw.
2. Camera Obscura - Pinhole camera
Each team built several camera obscuras, which were attached outside in different places of the school and our towns. In the period from October to April, our camera obscuras will take pictures of the Sun at different heights.
3. Researches report - Sun observations - sunrises, sunsets, shadow length
Sunrise and sunset times - The graph shows the shift in the hours of sunrise and sunset throughout October. Sunrises appear later and later, and sunsets appear earlier and earlier, which is consistent with the natural shortening of the day in autumn.
The length of the shadow is strongly dependent on the sun's elevation angle. A shorter shadow occurs at higher elevation angles, which corresponds to the noon hours of the day.
The solar azimuth angle changes predictably from sunrise to sunset, reflecting the Sun's movement across the sky
4. Photovoltaic cell construction
We built mini photovoltaic cells using the experimental photovoltaic kit "Solar assistant" and its instructions. The experimental set-up provides the opportunity to investigate the technology and characteristics of solar cells for energy generation.
Mobility - photo report.pdf5.Our photo report from e-Soleo mobility
Together we have prepared a photo report on mobility in our e-Soleo project:
21-25.11.2025 - Bilingual Primary School No. 1, Warsaw, Poland
10-14.03.2025 - Institut Joan Amigó i Callau in L'Espluga de Francolí, SPAIN
05-09.05.2025 - Dietrich-Bonhoeffer-Gymnasium, Bergisch Gladbach, Germany
6. Presentations and reports on solar radiation intensity in Spain, Poland and Germany.
Based on various scientific materials, information from specialist atlases and meetings with experts, we have prepared reports on the intensity of solar radiation in Spain, Poland and Germany.
Analysis of solar radiation intensity in Poland_en.pdfUsing solar energy in my school.pdf7. How do we use solar energy in our schools?
We prepared analyses of the use of solar energy in our schools. We conducted interviews, searched for information, talked to photovoltaic experts.
8. Oxford-style-debate
For almost a year, we have been exploring the topic of solar energy. We have built camera obscuras, performed sun dances, visited planetariums, fried eggs by using solar power, analyzed the energy of sunlight, built solar motors and talked about sun radiation in Europe.
Now as we approached the conclusion of our joint project, it is time to the ultimate question:
"Should solar energy in the form of photovoltaic systems become the primary energy source for Europe's population?"
9. eSoleo Podcast
Students created some Podcasts on Solar energy, solar energy in the different countries and the different climates. They also discussed if life would be possible without the sun and what the consequences would be.
