PS1 (5-6)-1Students demonstrate an understanding of characteristic properties of matter by …
1a comparing the masses of objects of equal volume made of different substances.
|
Lesson 2: Inquiry 2.2: Comparing the densities of the different Substances
Cylinder Demonstration |
Kit does not use objects of the same volume and compare their mass. (Cylinder Demonstration will be added to Lesson 2.) |
|
|
PS1 (7-8) –1 Students demonstrate an understanding of characteristic properties of matter by …
1a measuring mass and volume of both regular and irregular objects and using those values as well as the relationship D=m/v to calculate density.
|
Lesson 2: Inquiry 2.3: Measuring the densities of Irregular objects
Cylinder Demonstration |
Kit misleads students to believe that just blocks are regular shaped objects and they also refer to a cylinder as an irregular shaped object. (Cylinder Demonstration will be added to Lesson 2.) |
|
|
PS1 (5-6) –2 Students demonstrate an understanding of characteristic properties of matter by …
2a recognizing that different substances have properties, which allow them to be identified regardless of the size of the sample.
|
Ongoing throughout the First unit in Properties of Matter.

PS1 (5-6) – 4 Students demonstrate an understanding of states of matter by
4a differentiating among the characteristics of solids, liquids, and gases.
4b predicting the effects of heating and cooling on the physical state, volume and mass of a substance.
|
Lesson 7: Just A Phase
Lesson 5: Temperature and Density (Matter expands when heated and contracts when it cools.)
Lesson 8: Changing Matter and Mass (Conservation of Mass in a Phase Change)
Lesson 6: Applying the Heat |
Need to add notes on the characteristics of the three phases of matter. |

PS1 (7-8) – 4Students demonstrate an understanding of states of matter by
4a creating diagrams or models that represent the states of matter at the molecular level.
4b explaining the effect of increased and decreased heat energy on the motion and arrangement of molecules.
4c observing the physical processes of evaporation and condensation, or freezing and melting, and describe these changes in terms of molecular motion and conservation of mass.

Supplement for Lesson 5: Temperature and Density or Lesson 7: Just a Phase Videostreaming: Common Properties of Matter: Atoms, Elements & States (2 segments on the M drive - ”Closer look at the states of matter” & “States of matter”)
|
Kit does not cover these GSEs. The videostreaming segments address the gap |
|
|
PS1 (5-6) – 5 Students demonstrate an understanding of the structure of matter by …
5a distinguishing between solutions, mixtures, and “pure” substances, i.e. compounds and elements.
|
Lesson 11: Introduction
Lesson 15: Separating a Soluble and an Insoluble Substance
Lesson 19.1 Performance Assessment
Classification of Matter Chart (to be completed throughout Units 2 & 3) |
Kit does not distinguish between mixtures & solutions and identifying that a heterogeneous mixture is not a solution because solutions are always homogeneous mixtures. (These notes are addressed in the Classification of Matter Chart.) |

PS1 (7-8) – 5 Students demonstrate an understanding of the structure of matter by …
5a using models or diagrams to show the difference between atoms and molecules.
5b classifying common elements and compounds using symbols and simple chemical formulas.
5c interpreting the symbols and formulas of simple chemical equations.
5d using symbols and chemical formulas to show simple chemical rearrangements that produce new substances (chemical change).
