8th Grade Standard I-Objective 2 Evidence of Physical/Chemical Change

Standard I: Students will understand the nature of changes in matter.
Objective 2: Observe and evaluate evidence of chemical and physical change.

Enduring Understanding: In a physical change the identity of the atoms does not change. Evidence that a physical change has taken place include changes in shape, size or phase. In a chemical change, the identity of the atoms does change. Evidence that a chemical reaction has taken place include; color change, gas given off, and heat or light given off or absorbed. Atmospheric oxygen is a part of many important reactions. The properties of a substance may change if the substance has undergone chemical or physical change.

“I Can” Statements

  1. I can identify characteristics of a physical change.
  2. I can identify characteristics of a chemical change.
  3. I can explain why atmospheric oxygen important.
  4. I can predict what will happen to the properties of a substance after it has undergone a chemical or physical change.
