Watercycle (Streams, Rivers, Lakes and Oceans): 2nd Grade Science Workbook Children's Earth Sciences Books Edition

Where do waters in streams and rivers go? Where do oceans lead to? These are important questions that need good answers. Luckily, there are resources – like this book – that have been designed especially for 2nd graders. Big words and systems have been cleverly reworded to make sure that even the young ones would understand them on their own. Such simplicity leads to a spike in the interest of self-paced learning.
