Classifying Matter

Classifying Matter

Author: Ashley Davidson

The student will understand that all things in nature is made up of matter and anything that has matter also has mass.
The student will be able to recognize that all objects have certain properties and that objects can be classified based on those properties.

TEK 5.5A Classify matter based on physical properties including: mass, magnetism, physical state (solid, liquid, gas), relative density (sink or float), and solubility in water, and the ability to conduct or insulate thermal or electrical energy.

In this lesson, matter is defined and the properties of matter are identified and defined. The students will create graphic organizers that will show how matter can be classified. The students will also test the different properties of matter so the different properties can be identified.

Classifying Matter Lesson Instructions

In this lesson you will understand the properties of matter and how they are classified. Here are the key concepts of this lesson as stated by STEMScopes.

Key Concepts

Key Concept 1: Matter has physical properties that can be observed.

Key Concept 2: We can classify matter based on its physical properties using tools such as balances, magnets, and electric circuits.

Key Concept 3: We can classify matter based on its behavior such as ability to float or sink, attraction to a magnet, solubility in water, and ability to conduct heat or electricity.

Make sure you complete the independent work at the end of each sub-lesson. If you have any questions, feel free to email me or bring them to class the next day. It is okay to watch ahead! If you do, let me know and I will make sure you have the materials you need in order to take the next step in the lesson.

Get Ready for Class!

Here is what you can think about before coming to class:

What type of graphic organizer could you use to show the different properties of matter? Table? Venn Diagram? Family Tree?

How would you organize the information? What would the title of your graphic organizer be?


These are the questions you will work on in class and create a graphic organizer with your classmates.

Classifying Matter Vocabulary Part 2

This is finishes up the vocabulary for classifying matter. It defines the different properties that matter is classified by.
