Minnesota Academic s K-12 2009 version This official stards document contains the science stards revised in 2009 put into rule effective May 24, 2010.
Minnesota Academic s in Introduction The 2009 Minnesota Academic s in set the expectations for achievement in science for K-12 students in Minnesota. The stards are grounded in the belief that all students can should be scientifically literate. Scientific literacy enables people to use scientific principles processes to make personal decisions to participate in discussions of scientific issues that affect society (NRC, 1996). The stards benchmarks describe a connected body of science engineering knowledge acquired through active participation in science experiences. These experiences include hs-on laboratory activities rooted in scientific inquiry engineering design. The stards are placed at the grade level where mastery is expected with recognition that a progression of learning experiences in earlier grades builds the foundation for mastery later on. The Minnesota Academic s in are organized by grade level into four content strs: 1) The Nature of, 2) Physical, 3) Earth Space, 4) Life. It is important to note that the content skills in The Nature of are not intended to be taught as a st-alone unit or an isolated course, but embedded used in the teaching, learning assessment of the content in the other strs. Each str has three or four substrs. Each substr contains two or more stards one or more benchmarks. The benchmarks supplement the stards by specifying the academic knowledge skills that schools must offer students must achieve to satisfactorily complete a stard. Not all stards are found at every grade level. The strs, substrs stards are organized as follows. STRAND 1: NATURE OF SCIENCE AND ENGINEERING 1: The Practice of 1. Understings about science 2.

Minnesota Academic s in Introduction (continued) The stards are written as statements of content, the benchmarks are written as learning outcomes. Each stard should be prefaced with the statement, The student will underst that. Many of the benchmarks include examples that clarify the meaning of the benchmark or indicate the level of student understing. The examples may suggest learning activities or instructional topics. They are NOT intended to be directives for curriculum or a comprehensive fulfillment of the benchmarks. The benchmarks for each stard are designated by 5-digit codes. For example, in the code 3.1.1.2.1 The 3 refers to grade 3; The first 1 refers to the first str, The Nature of ; The next 1 refers to the first substr, The Practice of ; The 2 refers to the second stard in that substr, Scientific inquiry is ; The last 1 refers to the first benchmark for that stard, Generate questions that.
