Free discussion in Fluid lab

In response to one of my readers, I start to update this blog again. When I looked at the last post's date, I found that one year has passed, and it seems that I update my blog each year! anyway, hopefully I change this routine.
1- I am teaching a fluid lab this semester and we had a long experiment which provided some free time and I told the students they can talk about whatever they like. students started talking about different things until they reached "teen pregnancy" topic. " I lived in Amarillo, Texas and it had a high rate of teen pregnancy in Texas", one of students said. " what is the rate?" I asked. " I had a class with 20 pregnant students" he replied." it's so many!" I said. I was deeply thinking who is going to take care of these kids."what is the solution?" I asked students. " I control myself." the same student answered. " do you think putting some restrictions would be helpful?" I asked. but it seemed that nobody liked this idea. so I concluded that everybody should have self-control. I was again thinking that personal freedom is very important for these people, even if it creates some problems!
2- " Do you think America is ready for female president?" I asked in other class from students. " America is ready for female president, but not for Hillary", one girl responded. Another girl with the eyes full of anxiety said" she stayed in the relationship with Bill because of staying in White house!" I t seems that Hillary has a lot of enemies particularly among Women!
