Here is the perfect companion to anyone teaching physics in Grade 8! This book leads one through a deepening of students' understanding of Light, Sound, Heat and introduces electromagnetism in a way that combines previous experiences with magnetism and electricity. Hydraulics and contemporary machinery can be explained using this approach through direct experiences that the eighth graders have in class. Leaving students free to discover, avoiding telling them what has already been discovered, keeps lessons lively and learning at its peak! This is a delightful and lively way to teach physics
