In the
United States education system
, social studies is the integrated study of multiple fields of
and the
, including
,
, and
. The term was first coined by American educators around the turn of the twentieth century as a catch-all for these subjects, as well as others which did not fit into the traditional models of lower education in the United States, such as
and
.
In 1912, the
(not to be confused with its successor agency, the
United States Department of Education
) was tasked by then
with completely restructuring the American education system for the twentieth century. In response, the Bureau of Education, together with the
National Education Association
, created the Commission on the Reorganization of Secondary Education. The Commission was made up of 16 committees (a 17th was established two years later, in 1916), each one tasked with the reform of a specific aspect of the American Education system. Notable among these was the Committee on Social Studies, which was created to consolidate and standardize various subjects which did not fit within normal school curricula into a new subject, to be called "the social studies."
Animals with internal skeletons made of bone, called vertebrates, are actually the minority on Earth. As much as 98 percent of all animals are invertebrates, meaning they do not have internal skeletons or backbones.
The amount of bones a person is born with isn't the final tally later on. Human infants are born with about 300 bones, some of which fuse together as the body develops. By the time humans reach adulthood, they have 206 bones, according to
Arizona State University’s School of Life Sciences
. Human males grow until their late teens and females grow until two years after the beginning of their menstrual cycle, typically. This is when the growth plates on bones usually close, halting bone expansion.
Bone Density Decreases in Space
Bone loss is a serious issue that has plagued astronauts since the dawn of the Space age. In the microgravity environment bones are remodeled with a decrease in mineral density. Good nutrition, increased vitamin D intake and exercise are used to battle the issue aboard the ISS.
