Friday was our last day. In the morning, we split into two groups, one group visited the gym and the other group did some experiments with the students who are taking chemistry tests. When one group had finished, the two groups switched. The pupils carried out some interesting experiments, such as the Pharaoh’s serpents, the rainbow bottle, the fog and the elephant toothpaste. Students from other countries also took part in the experiments. Students successfully made a lava lamp and filled a balloon with CO2. After the two groups had exchanged places, we all gathered one last time to announce the winner of the match. But at the end, we all got certificates. And that’s the end of our week.
