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

Identify common classroom objects by one observable property, such as size or color.
General Information
Number: SC.1.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.

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

Shell Sorts:

A resource as plentiful as seashells on the beaches of Florida provides a great springboard for teaching about sorting objects by texture, size and shape. Your students will never look at these beautiful objects in the same way!

Type: Lesson Plan

Float or Sink?:

This lesson builds on lessons regarding the different properties of solids by having students explore how different objects float or sink when placed in water.

Type: Lesson Plan

Properties of Solids:

This lesson (intended to be used with other sorting lessons) allows students to understand the basic concepts of matter and properties of solids. This lesson involves the creation of a vocabulary chart with a child-friendly definition of matter and a Thinking Map with the varying properties of solids that students can use to sort different objects. Students explore two different objects and record their observations about the objects' properties.

Type: Lesson Plan

Sorting Matter:

Students will recognize that matter can be sorted by various properties.

Unit/Lesson Sequence

Observing and Sorting:

In this unit, students learn to make observations that clearly distinguish specific objects from others and how to sort items by different attributes (eg, color, size, weight).
