Science

Physical Science

Power Standards
  • Develop a model to describe that matter is made of particles too small to be seen. (5-PS1-1)
  • Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. (5-PS1-2)
  • Make observations and measurements to identify materials based on their properties. (5-PS1-3)

Critical Content

Concepts and Skills

* Power Standard Content

PS1.A: Structure and Properties of Matter

  • * Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means.  A model that shows gases are made from matter particles that are too small to see and that are moving freely around in space can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects. (5-PS1-1)
  • * The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish. (5-PS1-2)
  • * Measurements of a variety of properties can be used to identify materials.  (Boundary:  At this grade level, mass and weight are not distinguished, and no attempt is made to define the unseen particles or explain that atomic-scale mechanism of evaporation and condensation.) (5-PS1-3)

PS1.B:  Chemical Reactions

  • When two or more different substances are mixed, a new substance with different properties may be formed. (5-PS1-4)
  • No matter what reaction or change in properties occurs, the total weight of the substance does not change. (Boundary: Mass and weight are not distinguished at this grade level.) (5-PS1-2)

Critical Language (Science & Engineering Practices)

Language Usage

  • A student in fifth grade can demonstrate the ability to apply and comprehend critical language by identifying and describing matter in different states based on properties.

Concept-Based Connections

Essential Understandings

  • Matter can be identified by the observation and measurement of properties.
  • All matter is made up of particles that are too small to be seen but can be detected by other means.
  • No  matter what reaction or change in properties occurs, the total weight of the substance does not change.  (Mass and weight are not distinguished at this grade level.)

 

Factual Guiding Questions

  • What does conservation mean?
  • When matter changes, does its weight change?
  • Can new substances be created by combining other substances?
  • How do you know that the weight of matter is conserved?
  • What are some examples of physical properties?
  • What are some examples of chemical properties?
  • What are some examples of physical changes?
  • What are some examples of chemical changes?

 

Conceptual Guiding Questions

  • How do scientists effectively identify and analyze the properties of particles that are too small to be seen?
  • How can physical and chemical properties help identify an unknown substance?
  • How do we know if a chemical change has occurred?

 

Engaging/Debatable Guiding Questions

  • Do particles exist that have not yet been discovered by humans?
  • Can matter ever be lost through physical/chemical change?  How do we know this to be true?
