# Access Point #: SC.5.P.8.In.1

Identify basic properties of solids, liquids, and gases, such as color, texture, and temperature.
General Information
Number: SC.5.P.8.In.1
Category: Independent
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.

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

3 Methods for Measuring Volume:

This hands-on lesson plan allows students to investigate three methods for measuring volume. Students will learn to measure volume for liquids, regular-sized solids, and irregular sized objects. During the lesson students are exposed to demonstrations from the teacher and will participate in hands-on investigations utilizing three methods for measuring volume that they conduct and report to the class.
