School Improvement in Maryland

Using the State Curriculum: Science, Grade 7




State Curriculum Toolkit

Tools aligned to State Curriculum indicators and/or objectives.

  • Introduction for Standard or Indicator
  • Public Release Items
    Actual MSA items and annotated student responses as appropriate

Standard 4.0 Chemistry

Students will use scientific skills and processes to explain the composition, structure, and interactions of matter in order to support the predictability of structure and energy transformations.


A. Structure of Matter


  • 1. Cite evidence to support the fact that all matter is made up of atoms, which are far too small to see directly through a microscope.
  1. Recognize and describe that the atoms of each element are alike but different from atoms of other elements.
  2. Recognize and describe that different arrangements of atoms into groups compose all substances.
  3. Provide evidence from the periodic table, investigations and research to demonstrate that elements in the following groups have similar properties.
    • Highly reactive metals, such as magnesium and sodium
    • Less-reactive metals, such as gold and silver
    • Highly reactive non-metals, such as chlorine, flourine, and oxygen
    • Almost non-reactive gases, such as helium and neon
  4. Provide examples to illustrate that elements are substances that do not breakdown into smaller parts during normal investigations involving heating, exposure to electric current or reactions with acids.
  5. Cite evidence to explain that all living and non-living things can be broken down into elements.

Note: Highlighting identifies assessment limits. All highlighted Indicators will be tested on the Grades 5 and 8 MSA. The highlighted Objectives under each highlighted Indicator identify the limit to which MSA items can be written. Although all content standards are tested on MSA, not all Indicators and Objectives are tested. Objectives that are not highlighted will not be tested on MSA, however are an integral part of Instruction.
