Waterbending training

When both Katara and Pakku trained Aang the bending art of Waterbending, they both used several different techniques in order to train him.

Push and Pull
Since water is the element of change, many of the exercises in Waterbending requires some utilization of pushing and pulling water. Katara showed Aang how to do this by making small pushes and pulls in the water, making small waves. Pakku also explained to Aang, "You are manipulating the water, but you need to feel the push and the pull of it," while training him.

Streaming the Water
Named by Katara, it is a move that draws water from a source that Waterbenders move around their bodies. A more advanced version demonstrated by Aang apparently involves "sinking and floating". This move is thought to be used for basic training so that beginning Waterbenders can get a "feel" for water, but can be used for other techniques.

Making a Wave
Another Waterbending exercise meant to let the Waterbender know how to successfully manipulate large amounts of water. Katara attempted to make a large wave by slowly rising up a colemn of water, but she failed to make one and it fell apart. Aang then perfected it by quickly raising a larger wave, in doing so washing away their supplies.

Waterbending Scroll
The Waterbending Scroll is a scroll that was written in the Northern Water Tribe that was stolen from pirates by Katara. The scroll shows several basic Waterbending moves, including the water whip, water jet, water streams, and waves. The scroll helped both Aang and Katara about basic Waterbending, as the water whip proved to be very useful throughout the series. It was later donated to Wan Shi Tong's Library by Katara.
