SC.1.P.8.1

Sort objects by observable properties, such as size, shape, color, temperature (hot or cold), weight (heavy or light), texture, and whether objects sink or float.
General Information
Subject Area: Science
Grade: 1
Body of Knowledge: Physical Science
Idea: Level 2: Basic Application of Skills & Concepts
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.

Sink or Float?:

This lesson helps students explore different objects that may sink or float. The teacher will begin the lesson with two candy bars. The students will be able to touch and feel the weight of the candy bars and make predictions on whether the candy will sink or float. After the teacher performs the investigation students will be broken up into groups of three to four and will look at ten different objects and predict if they will sink or float. The students will record their predictions. Fill out a table with there findings and write about why there predictions were correct or incorrect. By the end of the lesson students should understand what a prediction is. They should also understand that objects with more air float.
