Identify that water can change from solid to liquid state by heating.
General Information
Number: SC.3.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. Matter can be changed physically or chemically.

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.

Unit/Lesson Sequence

States of Matter | Inquiry in Action:

In the first activity of this unit, students consider how heating and cooling affect molecular motion. The subsequent activities extend this idea to explore the relationship between temperature and the state changes of water. After considering their own experiences with evaporation and condensation, students discover that adding heat to water increases the rate of evaporation and cooling water vapor increases the rate of condensation. Students then investigate what causes moisture to form on the outside of a cold cup. As an extension, students see that at even lower temperatures water vapor can condense on the outside of a container and then freeze to form ice.
