Plant Structure and Adaptations
Non-vascular plants, like moss, are able to survive on photosynthesis. A video explains plant structure for both vascular and non-vascular plants. It includes the parts of each plant and adaptations to various environments such as...

What Triggers a Chemical Reaction?
Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...

Bozeman Science: The Equilibrium Constant
In the following video Paul Andersen defines the equilibrium constant (K) and explains how it can be calculated in various reversible reactions. The equilibrium constant is a ratio of the concentration of the products to the...

Bozeman Science: Le Chatelier's Principle
In the following video Paul Andersen explains how Le Chatelier's Principle can be used to predict the effect of disturbances to equilibrium. When a reversible reaction is at equilibrium disturbances will be offset to reach a new...
