Identify objects and materials as solid, liquid, or gas.

### General Information

Subject Area: Science
Body of Knowledge: Physical Science
Idea: Level 1: Recall
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

 Name Description Explore the States (of Matter): Glorious Gases This is the third lesson of three lessons designed for second grade students to understand and appreciate what matter is and which properties of matter are used to classify it as a solid, liquid or gas. If this lesson is used without the first lesson, Exploring the states (of Matter): Super Solids, the attached PowerPoint could be shown to as a preview to this exploration. Explore the States (of Matter): Super Solids This is the introductory lesson of three lessons designed for second grade students to understand and appreciate what matter is and which properties of matter are used to classify it as a solid, liquid or gas. Because solids are the most familiar form of matter for children, a shorter exploration of solids is included as the hands-on component to accompany the PowerPoint that discusses all states of matter. States of Matter In this 2-3 part session, students will manipulate printable objects and sort them into the three states of matter-solid, liquid and gas. They will also participate in a hands-on group investigation and record their observations into their Science Notebooks. A quiz on the content is also provided. The Shape of Kisses This resource features a lesson plan for comparing the properties of Hershey's chocolate kisses in different states: solid and liquid. Explore the States (of Matter): Lovely Liquids This is the second lesson of three lessons designed for second grade students to understand and appreciate what matter is and which properties of matter are used to classify it as a solid, liquid or gas. If this lesson is used without the first lesson, Exploring the states (of Matter): Super Solids, the attached PowerPoint could be shown to as a preview to this exploration. What's the Matter? This is a lesson where students will identify the properties of matter by their shape, color, size, texture and sink or float. Students will learn about how atoms make up matter through a hands on activity titled "Marshmallow Atoms." They will also be using their daily science notebooks. You Name It! Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses — sight, sound, smell, texture and taste — to identify the other characteristics of each item.

#### Teaching Ideas

 Name Description Investigating Oobleck: Solid or Liquid? The students will make their own predictions and conclusions on whether Oobleck is a solid or liquid by using focus observations, conducting focus explorations, raising questions, clarifying questions, and making conclusions about Oobleck. Solid and Liquid Stations Students investigate the properties of solids and liquids. Solid or Liquid? In this chemistry lesson students will investigate if certain materials are solids or liquids. Students are expected to make predictions, record observations, draw conclusions, and formulate questions for further investigation.

#### Text Resource

 Name Description Understanding Mass and Matter This is an idea of how to teach mass and matter with good examples that children can understand.

#### Unit/Lesson Sequences

 Name Description Water 1: Water and Ice In three connected lessons students observe and describe water as it changes state. In Water 1: Water and Ice, students explored how water can change from solid to liquid and back again. In the second lesson, students will focus on the concept that water can go back and forth from one form to another focusing on a liquid changing to a gas. In the third lesson, students investigate what happens to the amount of different substances as they change from a solid to a liquid or a liquid to a solid. Matter: Solids In this unit, properties of matter are introduced and solids are explored. Exposure to the engineering design process synthesizes information learned about solids and asks students to create a homemade play dough recipe.
