Conny, Siska, Martin and myself just — we came back home only yesterday! — ran a summer camp for teenagers called “Forscherfreizeit Ratzeburg”. The idea was to combine a fun summer holiday experience at a beautiful lake with all kinds of opportunities for doing experiments as well going sailing, swimming, hiking, you name it. And we had a great week!
Today I’m gonna show you lots of pictures for a general overview, and then I’m gonna post on experiments and our experiences with the Forscherfreizeit over the next couple of days.
So, obviously, we began with some team building. What you see in the picture below is a tower tumbling over after the participants had build it using a wire sling which they had to coordinate using long ropes. Luckily we had a great group and they all got on really really well.
Which meant they maybe even had a little too much fun occasionally. Hence the most relaxing part of our day was just before breakfast, when all the kids were fast asleep and we could go for a swim in the quiet lake. How beautiful is this?
And if you have ever wondered how difficult it is to swim and take pictures at the same time with the horizon being close to horizontal, I can tell you: very difficult indeed.A little later and the lake wouldn’t be as quiet any more…
After a well-deserved break…
…it was time to take the raft out on the lake and sail into the sunset.
Then on the next day, it was time for some experiments! As I said, I’ll talk about all the “interesting” (as in “new to this blog”) experiments later, so for now I’ll just mention that, obviously, we had to do the melting ice cube experiment.
And a real highlight were, of course, the model boats. Especially playing with a remotely controlled submarine which is explicitly designed for use in bathtubs and NOT in lakes… ;-)
And putting wood instead of a candle in a steam boat is also a lot more fun :-)The participants’ fascination with the toy boats resulted in an impromptu project: build your own toy boat and develop a good propulsion system!
For the instructors’ boat we had the brilliant idea to use the coke & mentos thing that you always hear about. So in order to keep the marina clean (imagine all the sugary stickiness on the nice sailing boats!) we took a raft out on the lake to test our boat. Unfortunately we were slightly underwhelmed by the result…
Very pretty, but not exactly what we had hoped for.
Anyway, we’ll be back soon!
