Have you ever seen a piggy bank where you put your allowance or some coins? A leaf bank is kind of like that, but instead of coins, it collects leaves that fall from trees in the autumn.
In the fall, the leaves turn beautiful colors and fall from the trees. People use rakes or leaf blowers to collect these fallen leaves and put them into a big bag or container. This container is called a leaf bank.
Just like how you can save your money in a piggy bank, people save these colorful leaves in a leaf bank. They can use them for many things such as making art, composting, or creating decorations for their homes.
So, in a nutshell, a leaf bank is a container where people save colorful leaves that have fallen from trees in the autumn. It's like a piggy bank for leaves!
