Priority standard (PS), Target Standard (TS), Learning objectives (listed by 3-number code)

PS-1 Matter, measurements, inquiry & Technology – Qualitatively and quantitatively describe matter     

  TS-1.1 Scientific method & inquiry- The process of science is investigation, which can be defined as a set of practices that allows for identifying and controlling variables

(NOTE - TS-1.1 is meant to be integrated in the standards throughout the year)                                                      

    1.1.1 Distinguish between qualitative & qualitative observations and interpretations.       

    1.1.2 Be able to formulate a testable hypothesis based on observations, interpretations, prior evidence, and/or scientific models.                                                                                       

    1.1.3 Be able to design and conduct a controlled experiment that tests a hypothesis which outlines the independent (experimental), dependent & controlled variables                

    1.1.4 Determine procedures & equipment used to safely conduct controlled experiments.         

    1.1.5 Determine appropriate data collection procedures for a controlled experiment  

    1.1.6 Process data which best shows the relationship between the independent vs. dependent variables from a controlled experiment.                                                                               

    1.1.7 Formulate conclusions of a controlled experiment based on analyzing and interpreting data         

    1.1.8 Evaluate the design of a controlled experiment by identifying sources of error.     

    1.1.9 Discuss how accepted scientific hypotheses can become scientific theories and/or laws  

    1.1.10 Discuss the role of scientific research in society & how it contributes to knowledge    

  TS-1.2 Classification & Properties of Matter - Matter can be classified as different forms by physical and chemical properties/changes                                                                

    1.2.1 Explain how physical & chemical properties are used to describe and/or differentiate the forms of matter 

Key Terms: physical properties, chemical properties, extensive properties, intensive properties

    1.2.2 Explain how specific signs can be used as indicators of physical or chemical changes.

    1.2.3 Use a model to distinguish between mixtures, compounds & elements based on physical & chemical properties                                                                                   

    1.2.4 Differentiate homogeneous and heterogeneous mixtures based on composition            

    1.2.5 Differentiate the two pure substances (compounds and elements) based on chemical changes

  TS-1.3 Scientific measurements, Conversions & Dimensional Analysis- Science communicates the understanding of the physical world through mathemetical models.  

    1.3.1 Differentiate between the accuracy and precision of scientific measurements      

    1.3.2 Explain how significant figures are used to represent the level of accuracy of a scientific measurement 

    1.3.3 Solve mathematical calculations using appropriate significant figures as part of the answer         

    1.3.4 Represent scientific measures in scientific notation                    

    1.3.5 Identify the SI units of measure                                                    

Key Terms: Mole, molar mass

    1.3.6 Use metric system prefixes to represent the magnitudes of a measure      

    1.3.7 Convert between units of a measure.                                          

Key Terms: equality, conversion, dimensional analysis

    1.3.8 Solve mathematical problems using dimensional analysis          

    1.3.9 Assess outcomes by calculating percent errors
