# Contents pane

The Contents pane brings together parts and models designed for a range of learning topics. Each topic folder holds lesson kits that contain all the parts needed to create a model. Click on a folder to open or close it. Only one folder and sub-folder can be open at a time.

Additional models on a particular topic can be found in the Other Examples folders. These models are created using parts from the Parts library.
