Edit; i failed my earth science regents, but because of multiple choice and short answer, this video still definitely helped. I did very well on my practical.
Fantastic. Love your enthusiasm. I wish you had been my teacher in school-i might have become a geologist! Is it possible for you to post your crib sheet of the different rock type characteristics for this 67 yr old student?? To the kids: enjoy and appreciate your teacher! Keep on learning for life!!
