Working Day 3

Friday April 13 2018

After getting started musically, a diverse workshop programme was awaiting us.

In one of those, for example, we continued a project from yesterday: We created an astronomy version of the game "Eurostronomia" and paid attention to every little detail on the cardboard. This activity was a perfect opportunity to make new friends. In the end we had created a wonderful game of which we are very proud.
Another really interesting workshop was about "Newton's Third Law", during which we made little rockets out of almost empty water bottles and "shot" them into the air. But we also did other experiments in order to understand Newton's laws. In one of them, one student had to push the other one away - while standing on a skateboard. This way, it was easy to understand Newton's ideas. After having learned Newton's laws, we continued the workshop with decorating empty water bottles which were going to be shot into the air - just like real rockets. When the rockets were ready and, mostly, looking nice, we went outside to launch them. In order to do so, we filled them with a little bit of water and connected them to an air pump. Then we just had to pump. When there was enough pressure in the bottle, it came off the flexible tube and flew up into the air. We had a lot of fun during this exercise - even though some of us did get a little wet.
In another workshop, we debated about whether or not colonising Mars was a good idea. It was a little difficult for us Germans to join the debate at first because of the language (and also most of the other students being older than us) but after we had overcome these small obstacles, debating with pupils from different countries was a lot of fun.
There also was a workshop on Earth in relation to Sun, Moon and Venus. This exercise was well-illustrated with a globe and a model of the moon. Through seeing what we were talking about in front of us, learning was much easier than some probably expected it to be. We also really liked how a senior student did the presentation because she was explaining everything very vividly.
The photos of different stars and planets, e.g. Sun and Saturn, were being worked on in another workshop. Those were firstly taken by a camera attached to a telescope. It was very impressive to see how much the use of a special programme had raised the quality of the photos taken.
We measured the light coming from a distant solar system and by analysing this light we could make some conclusions about the possible existence of an exoplanet. For this we also did an experiment with light detectors and a mini sun system. This very complicated system was clearly and vividly explained to us so that we could precisely understand the way in which exoplanets can be found. The common work that we did with students from other countries helped us to get to know each other better.

In another workshop we learned how to measure the distance from the Earth to the moon using two special photos of the moon. The most interesting thing was the physical reasons for the tides and also why due to scattering of light the sky is blue and in the morning and the evening the sun is red. It was impressive that we could, when looking at a photo of the Christ the Redeemer statue in Rio de Janeiro, calculate the exact position of the camera - just by looking at the sun. Although the tasks were difficult and complicated, especially because everything was explained in English, we found it very interesting and had a lot of fun.
In the evening of this very interesting day there was another spectacular activity planned. At 7pm all students got on a bus and drove up a hill in order to go stargazing. Because of the low population in Slovenia's forests and a clear sky we had a perfect view of all the different stars and constellations that a teacher explained to us. But it got even better: through two professional telescopes we could watch planets, like Venus and Jupiter, and stars. After having got back on the bus, we all agreed that this day was - again - incredibly impressive and unique.
