A yeshiva Stduents Guide to Topics in Earth Science is a unique product designed for Yeshivos that would like to use their secular textbooks but do not want to use them when teaching problematic content found in the Earth Science. Working with Rav Chaim Yisroel Belsky zatza"l, Rabbi Brody drew up these small pamphlets under Rabbi Belsky's guidance and instruction and were throughly reviewed by Rabbi Belsky as well. So, go ahead and try it. You wont be disappointed!
