المصدر: 101Science Experiments: Basic Principles Made Clear by Simple Demonstrations في منتدى : قسم الفيزياء 101 Science Experiments: Basic Principles Made Clear by Simple Demonstrations Publisher: Odham's Press, London | ISBN: n/a | edition 1962 | PDF | 155 pages | 22 MB This is a big, colorful, fun science book. It is full of fun practical science demonstrations, many of which can be done with common household items. This book is at a level that young gradeschoolers can understand, and covers science topics as high as middle school levels. It covers eleven different areas from air and gases to motion and machines. I have done many of these projects with my children. I even used the "Make a Rainbow" demo from the Color section in my Sunday school class while teaching about Noah. This book is a great addition to a homeschool library.
