Friday the 13th 2014, we were going to the RUZ (Regional Umwelt Zentrum) to do our activities.

Our stop was the last of all, so we had to be in the bus for one hour and a half or two hours.

When we arrived, the teachers talked with a man and he said that we had to walk two kilometres. Then, we met Dagmar´s husband and told us to cross a bridge and then, the bus will come to pick us up to the RUZ.

 

 

There, we made groups of three and we picked insects in a pond. We also mesured the oxygen in that pond and another smaller that had more plants.

Friday we went to a museum about the Wadden Sea. First we got a lot of information about the Wadden Sea. Then we split up in two groups were one group had to do experiments with salt water and the other had to learn about the animals in the Wadden sea. At the salt water experiments we first had to make our own salt water mixture. The salt felt to the bottom of the water like in death sea. Then we have to compaire our mixture with a fresh water and water from the north sea. We put each kind of water on a little plate. Then we put the plate on a hot plate one by one. The north sea water evaporated and a bit of salt were left on the bottom of the plate. The saltwater mixture evaporated and left a lot of saltwater on the plate. The fresh water did not leave any salt.
