STEM offshoot can be described as a TWIG, which is a four-letter word. A TWIG is a thin, flexible branch of a tree or shrub that typically has many small side branches. Twigs are important for the growth and development of trees and shrubs, as they provide support for leaves and flowers. Twigs also provide food and shelter for birds and other animals. Twigs are often used in crafts and decorations, such as wreaths and floral arrangements.
