Agriculture Throughout The Years

This WebQuest is to allow students to dig deeper into the agriculture that has become a large industry in our economy.  I have come to know that Agriculture Education is not always offered in schools, and this will allow students to learn without it being a specific class.  There are many diverse areas that fall into multiple agriculture categories.  This is a broad project, and can be modified to a specific subcategory to fit the time and needs of not only the students, but teacher as well.
