Access Point #: SC.8.P.9.Su.1

Observe and recognize physical changes in matter as able to change back (reversible), such as water to ice, and chemical changes of matter as unable to change back (irreversible), such as cake to cake batter.
General Information
Number: SC.8.P.9.Su.1
Category: Supported
Date Adopted or Revised: 02/08
Big Idea: Changes in Matter : A. Matter can undergo a variety of changes.

B. When matter is changed physically, generally no changes occur in the structure of the atoms or molecules composing the matter.

C. When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A and B.

Clarification for Grades 6-8: The target understanding for students in the middle grades should begin to transition the focus to: C. When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

Lesson Plans

Cooking in the Chemical Kitchen:

Changes in matter are explored both physically and chemically through a variety of experiments.

Type: Lesson Plan

“It's Time for a Change”:

Physical changes do not change what things are made of, but chemical changes do change what things are made of.

Type: Lesson Plan

Time to Change the Baby!?!?!?:

In this open inquiry activity, students will explore what it is that keeps a diaper-wearer "dry" and whether it is chemical change or physical change.

Unit/Lesson Sequence

Middle School Chemistry Unit | Chapter 6 | Chemical Change:

Students explore the concept that chemical reactions involve the breaking of certain bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students also design tests to investigate how the amount of products and the rate of the reaction can be changed. Students will also explore endothermic and exothermic reactions.
