Ch 3.1 States of Matter

Ch 3.1 States of Matter

Author: deirdre carney
  • Describe the five states of matter
  • Classify materials as solids, liquids, and gases
  • Explain the behavior of gases, liquids, and solids using kinetic theory

Nevada Science Standards

P.12.A.1 Students know different molecular arrangements and motions account for the different physical properties of solids, liquids, and gases. E/S 

Next Generation Science Standards

MS-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. 

HS-PS3-2. Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles (objects).

Chapter 3.1 Solids, Liquids, and Gases

Read Chapter 3.1 Solids, Liquids and Gases pg 68-74. Outline the reading in your Science Notebook & include major points and diagrams/tables.
You should focus on the following essential questions:
-How can shape and volume be used to classify materials
-How can kinetic theory and forces of attraction be used to explain the behavior of gases, liquids and solids

Video Clip: Matter

Watch video and take notes in your science notebook. NOTE: Please pay attention to the discussion of how matter is classified (Pure Substances vs Mixtures). We will not be covering this in tutorial but it will be in the following tutorial!

Video Clip: Changing States of Matter

Watch video and take detailed notes in your science notebook. Pay attention to this question: "Why does the temperature of a substance stay constant at its melting and boiling points?" Where is the energy going?

Virtual Lab - States of Matter


Complete the Journal questions and graph (handout provided). Be sure to observe the changes in each substance as temperature is changed.

In this Virtual Lab you will examine how energy affects the state, the atomic or molecular activity, and the temperature of a substance.
• Explore how thermal energy affects different states of matter.
• Describe how the temperature of a substance is affected by changing states of matter.
• Interpret and analyze temperature versus time graphs.
• Observe how the movement of atoms or molecules is affected by changes in thermal energy.
