First of all, our old friend came back to visit!! Some students did not return to GVA this year. But they are always one of us and we all miss them a lot!! It was great to see my old student.
We had water cycle for the first week and basic water properties on second week. We talked about how water transfer in the world and how do they keep this world alive. Here is a short video that one student made up a song for it. It was quite during the taping but they laughed so loud after that.
They also learned water surface tension, we did a little experiment for that. They need to use burette to drop water on a nickle and record on a chart that how many drops they can do before it breaks the surface tension. Learning by doing, the best way to learn.
