Welcome to TEKS-Science

      At this site you will find the essential knowledge and skills and corresponding student expectations for grades kindergarten through high school in the area of science.  The site is easy to use and simply organized.  Clicking the Concept Map icon at the bottom of the menu in the left hand frame opens a flow chart which shows the relationship between scientific processes and science concepts.  The concept and process areas include facts and procedures that students acquire and refine across the elementary and secondary grades.  Ultimately, this knowledge base combines with concepts originating in areas such as aquatics, astronomy, biology, chemistry, geology, meterology, oceanography, and physics.  The result is an understanding of how measurement and observational tools are used in laboratory- and field-based studies to answer specific questions and to provide reliable, interpretable information for decision-making, theory building, and further investigation.  The Concept Map opens in its own, nonresizable browser.  It can be moved or printed or overlayed on the parent browser so that specific knowledge and skills can be viewed in the context of the "breadth and scope" of Science.

     Concept Strands are clusters of TEKS that share a common principle or principles.  These clusters can be vertically linked across grade levels to develop innovative curriculum models.  These kinds of models focus on "big ideas" of science (i.e., principles) rather than solely on the traditional disciplines of science.  Hence, learning is depicted as a complex, reciprocal process.  Higher order thinking and inquiry skills develop from an understanding of common principles in the early grades then serve to broaden understanding across concepts as new information and skills are incorporated into common principles.

     To navigate through this web site, click on a grade level (kindergarten is the default level when you enter the browser) and a subject matter link in the frame to the left.  This (right-hand) frame then displays the processes and principles used to organize essential knowledge and skills defined for that grade level or subject matter area.  If you want to see how knowledge and skills change over grades and subject matter areas, click on a Process or Concept Strand and then click through the grades and subject matter areas.  The TEKS will appear in this frame.  Clicking on the Overview button will place the selected grade or subject introductions into the this frame.  These overviews communicate general ideas about grade level and subject matter content and should help teachers form educational goals that can be used to guide teaching.  Click on any Process or Concept Strand and the TEKS specific to that area, along with the TEKS numbers, appear in a table in this frame.  To print, highlight the frame and then select the Print Frame command located in the File directory on the browser menu bar.  An active frame can be saved by clicking on the Save Frame As command also located in the File directory on the browser menu bar.
