Thinking in Matter & Energy - Level 5 - Cycles and Flows

The video explores the concepts of matter cycling and energy flow within systems. It begins with an introduction to these concepts, followed by a practical demonstration using a single-path marble run to illustrate how matter cycles and energy flows. The video then transitions to a backgammon game example to show matter flow and energy in a different context. Throughout, the importance of defining the system and understanding the role of energy in moving matter is emphasized.

What is the first step in investigating a system according to the video?

Explain how matter can cycle in a system.

Describe the relationship between matter cycling and energy flow.
