The four plants that make up a lulav bundle symbolically represent parts of the body:

the tall, straight palm branch represents the spine that supports the whole body;

the etrog represents the heart that pumps blood around the body to keep everything working;

the willow leaves represent lips, which should only be used for polite and helpful speech;

the myrtle leaves represent eyes, which notice everything in the world around.

Sukkah means “covering”, so the most important part of a sukkah is its roof, what must be made of natural materials such as branches or straw etc, and not metal or plastic. It must also give more shade than is open to the sky.

There are many rules about how to build a sukkah that is kosher (fit for purpose). For example, it must have at least 3 walls, just over half a metre long and a metre high, and must be under the open sky, not inside a building or under a tree.
