School Improvement in Maryland

Using the State Curriculum: Science, Grade 3




State Curriculum Toolkit

Tools aligned to State Curriculum indicators and/or objectives.

  • Introduction for Standard or Indicator

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. Identify ways to classify objects using supporting evidence from investigations of observable properties.
  1. Classify objects based on their observable properties.
  2. Provide reasons for placing the objects into groups.
  3. Compare classifications with those of others.


  • 2. Identify and describe structures of objects too small to be seen clearly with the unaided eye.
  1. Identify and describe minute objects, such as grains of sand and crystals of salt after examining them with a magnifying instrument.
  2. Identify and describe the minute features of objects, such as the lines (grain) in a piece of wood and the fibers in a paper napkin after examining with a magnifying instrument.


C. States of Matter


  • 1. Provide evidence from investigations to describe the effect that changes in temperature have on the properties of materials.
  1. Based on data gathered from investigations, identify and describe the changes that occur to the observable properties of materials when different degrees of heat is applied to them, such as melting chocolate pieces, boiling an egg.
  2. Observe and describe the changes cooling causes to the observable properties of materials when they are cooled, such as freezing water in a straw, milk in an ice cream maker.
  3. Cite examples of similar changes that heating and cooling have on the observable properties of various other materials.

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.
