Eighth Grade Science
Course Outline

No one can become really educated without having pursued some study in which he took no interest. For it is part of education to interest ourselves in subjects for which we have no aptitude.

T S Eliot

See the Texas Essential Knowledge and Skills for Science at http://www.tea.state.tx.us/rules/tac/chapter112/index.html.

Below is the proposed scope and sequence for this year.  Education is a dynamic enterprise, and this may be revised at any time to accommodate the changing needs of the students.
