# Access Point #: SC.8.P.8.Pa.1

Recognize examples of the gaseous state of matter, such as steam or smoke.
General Information
Number: SC.8.P.8.Pa.1
Category: Participatory
Big Idea: Properties of Matter : A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass which gives it inertia.

B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

The concepts of mass and weight are complicated and potentially confusing to elementary students. Hence, the more familiar term of "weight" is recommended for use to stand for both mass and weight in grades K-5. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.

Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2.

Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

## Lesson Plan

The movement of particles in solids, liquids, and gases.:

Students will be able to describe the motion of the particles in solids, liquids, and gases.

Content statements:
- The particles of a gas move quickly and are able to spread apart from one another.
- The particles of a liquid are able to move past each other.
- The particles of a solid are not able to move out of their positions relative to one another, but do have small vibrational movements.
