Conservation of Mass and Energy

Grade levels:

This theme focuses on helping students use scientific inquiry to discover patterns, trends, structures and relationships that may be inferred from simple principles.

These principles are related to the properties or interactions within and between systems.

STRANDS
Strand Connections: Systems can exchange energy and/or matter when interactions occur within systems and between systems. Systems cycle matter and energy in observable and predictable patterns.

This topic focuses on the empirical evidence for the arrangements of atoms on the Periodic Table of Elements, conservation of mass and energy, transformation and transfer of energy.

CONDENSED CONTENT STATEMENTS

7.PS.1 Elements can be organized by properties.
7.PS.2 Matter can be separated or changed, but in a closed system, the number and types of atoms remains constant.
7.PS.3 Energy can be transformed or transferred but is never lost.
7.PS.4 Energy can be transferred through a variety of ways.
