The
Cycles of Life series examines biological organisms interacting with their environments and other forms of nature, using the scientific method as a learning tool whenever new topics are addressed. This episode provides important information about atoms, molecules, compounds, elements, and other forms of matter. Several segments also look at how different forms of matter react to various environments. Microvideography, 3-D animations, and special laboratory footage help bring each subject into focus throughout this series. ~ Elizabeth Smith, All Movie Guide
