The word “research” comes from the French word recherche, meaning to search. It uses a very strict set of method (scientific investigation, also called the scientific method”) to understand nature, and how it works.
The results of research studies have provided new findings (evidence) that have shaped the way we understand the world in every different area of science. In the context of children this includes understanding the biology of child development, understanding how food and nutrition influence their health and how to treat and prevent childhood medical conditions. It has also led to the production of new inventions and technology.
