Exploring at Recess
I think what happened was one girl showed an interest, and some others followed the lead.
This herd mentality has happend before in my class this year. I remember I was reading a book and not many students were interested in it. All it took was one of the bigger personalities in the class to become excited, and before I knew it, most of the students in the class were excited too. I should do an experiment about that.
While I think it is great that the girls are taking what they learned in class and acting on it in their own time, I think it is time for them to do more than just crush rocks. I am thinking about having them do a picture presentation showing what the rocks look both on the inside and outside. I would also like them to identify the rocks.
