Chalk on a chalkboard is one of the worst feelings through my body but I guess it would be most limestone since chalk is made of it!
Chalk definitely creeps me out they should ban the sale and distribution of it.
Yes, especially since you rarely see the old style blackboards made of slate stone anymore.  It seems like colleges use the term blackboard for online stuff more then it is actually used.
Yeah it's not something that is used much with dry erase boards in most class rooms. Only old classrooms have it and I imagine they will be phased out.
Especially with how much technology is taking over and whiteboards being used as a writing pad and software application.
The sound of nails on a chalkboard is really the worst, but you know I might miss it. It can be very nostalgic.
Well you could always watch a YouTube video with it and future teachers can put that on for their students so they don't miss out either haha. It would integrate old school and technology and get students to understand more of the past!
Well either way they are going away and piece of history with it.
That is true but with technology being so prevalent I can see in the future watching videos made on You tube to help preserve our present and  letting the future live through our eyes.  You tube has even helped change history so it can preserve as well.
Unfortunately videos on the internet lose their human touch and we lose are connections to others through it.
