# Big Idea 8: 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 Plans

What is so COOL about my Robot? Warm and Cool Colors:

In this lesson students will create works of art using a painted, warm colored background and a cut and pasted, cool colored robot.  This lesson will reinforce warm/cool colors and geometric shapes in a work of art.  Students will demonstrate mastery of sorting and selecting warm and cool colors.

Type: Lesson Plan

Observable Properties of Matter:

Students will sort objects according to their observable properties, such as size, shape, color, temperature (hot or cold), weight (heavy or light) and texture.

Type: Lesson Plan

Finding the One!!:

Students will sort and classify rocks by observable properties, such as size, shape, color and texture. (The properties of temperature and weight are not addressed in this lesson).

Type: Lesson Plan

The Fire Wheels:

The Fire Wheels MEA provides students with a problem in which they must work as a team to design a procedure to select the best toy car for a company to sell.

Type: Lesson Plan

Sort it Out!:

In this lesson, students will use a graphic organizer to record their observations on sorting matter from the read aloud book Sorting by Lynn Peppas.

Type: Lesson Plan

Learn About the Parts of a Plant:

This lesson supports students interacting with nature and provides them with a framework for their observations by offering them opportunities to explore, question, and document similarities and differences among plant parts.

Type: Lesson Plan

Sorting Junk!:

In this lesson, students will sort junk boxes to help them understand Physical science benchmarks. Students will also access website to reinforce sorting and technology skills.

Type: Lesson Plan

In this lesson, students will learn common antonyms and will participate in an antonym matching game. They will also learn to sort objects based on a common pair of antonyms, "big" and "small". They will use their understanding of the words "big" and "small" to describe objects, both orally and in writing.

Type: Lesson Plan

Sorting by Shape and Color:

Students will sort various objects by shape and color in cooperative groups.
