SC.5.P.8.3

Demonstrate and explain that mixtures of solids can be separated based on observable properties of their parts such as particle size, shape, color, and magnetic attraction.
General Information
Subject Area: Science
Grade: 5
Body of Knowledge: Physical Science
Idea: Level 2: Basic Application of Skills & Concepts
Big Idea: Properties of Matter - A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass.

B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

The concepts of mass and weight are complicated and potentially confusing to elementary students. Hence, the more familiar term of "weight" is recommended for use to stand for both mass and weight in grades K-5. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.

Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2.

Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

Test Item Specifications
  • Item Type(s): This benchmark may be assessed using: MC item(s)
  • Also Assesses
    SC.5.P.8.2
    Investigate and identify materials that will dissolve in water and those that will not and identify the conditions that will speed up or slow down the dissolving process.

  • Clarification :
    Students will describe and/or explain how mixtures of solids can be separated.

    Students will identify common materials that dissolve in water.

    Students will identify or describe conditions that will speed up or slow down the dissolving process.
  • Content Limits :
    Items assessing conditions used to speed up or slow down the dissolving process are limited to temperature, stirring, and/or surface area.

    Items will not use the terms solution, solvent, solute, saturation, or catalyst.

    Items will not assess the difference between a mixture and a solution.
  • Stimulus Attributes :
    Dual thermometers showing degrees Fahrenheit and degrees Celsius must be used if the scenario requires an illustration of a thermometer.
  • Response Attributes :
    None specified
  • Prior Knowledge :
    Items may require the student to apply science knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge from SC.K.P.8.1 and SC.1.P.8.1.
Sample Test Items (1)
  • Test Item #: Sample Item 1
  • Question: Dani adds 10 grams (g) of salt to a jar of water. She then adds 10 g of sand to a second jar of water. She covers and shakes both jars and sets them on the table for five minutes. The materials Dani used are shown below.

    what should dani expect to observe after those five minutes?
