This is a picture of a science lab in singapore as there is a singapore flag behind. The students are having their science lesson in the lab doing experiment on the pulley system. On the table in the foreground, there are four students who are listening to the explaination made by the woman on the left of the picture who is probably the teacher.Two of the students are taking notes while the other two are looking at the pulley seriously, with the student on the right wanting to try out the experiment. The students are probably still in primary school and right now , they are having some group work as another group can be seen at the back of the picture.
