Ch 9: ILTS Environmental Science: Structure and Properties of Matter

About This Chapter

Let this chapter help you understand and apply knowledge of the structure and properties of matter. The video lessons and self-assessment quizzes give you the information you will need to correctly answer these types of questions on the ILTS Environmental Science test.

ILTS Environmental Science: Structure and Properties of Matter - Chapter Summary

The lessons in this chapter give you a look at the states of matter and its properties. You will study the atomic structure of matter, learn about the properties of matter in relation to chemical or physical structures and explore how kinetic theory applies to matter. Another lesson looks at the technologies and instruments used by scientists to study energy and matter. The videos cover these topics that will equip you for the test:

  • Liquid, gases and plasma
  • Common chemical reactions and energy change
  • Evaporation, condensation, freezing, melting, sublimation and deposition
  • Endothermic and exothermic reactions
  • Definition and examples of nuclear reaction
  • Covalent bonding and electron shells
  • Ionic bonds
  • Definition of elements and how compounds and molecules are formed from elements
  • Properties of solids and liquids and the kinetic molecular theory

Taught by experienced instructors who know what you'll need to prepare for the exam, these videos are both informative and entertaining. You will learn about the properties and structure of matter and have fun while doing it.

Objectives of the ILTS Environmental Science: Structure and Properties of Matter Course

Anyone who wants Illinois certification to teach environmental science at the secondary level must pass the Illinois Licensure Testing System (ILTS) environmental science content area exam. This exam contains 125 multiple-choice questions and is divided into six subareas. The questions covering topics from the Structure and Properties of Matter are in subarea IV, which deals with the Earth's systems and the universe. Through the self-assessment tests included with each video lesson, you can review what you've learned and familiarize yourself with the exam's format.

States of Matter: Solids, Liquids, Gases & Plasma

1. States of Matter: Solids, Liquids, Gases & Plasma

Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.

Common Chemical Reactions and Energy Change

2. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

3. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.

Endothermic and Exothermic Reactions

4. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.

Nuclear Reaction: Definition & Examples

5. Nuclear Reaction: Definition & Examples

Learn the differences between a nuclear reaction and a chemical reaction. Also learn how the nuclear reaction involves subatomic particles including protons and neutrons. Discover the different types of nuclear reactions including fission and fusion and also how a nuclear power plant works to produce energy.

Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule

6. Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule

Learn about the different electron shells of atoms as well as the octet rule for valence electrons and how that applies to covalent bonding. Discover the definition of covalent bonding and the relationships between atoms.

Ionic Bonds: Definitions and Examples

7. Ionic Bonds: Definitions and Examples

Did you know that when atoms stick together to form molecules, they gain and lose electrons, making them negatively or positively charged? In this lesson, you will learn how cations and anions form one type of chemical bond called an ionic bond.

Using Atoms and Ions to Determine Molecular Formulas

8. Using Atoms and Ions to Determine Molecular Formulas

In this lesson, you will learn how atoms and ions determine molecular formulas. You will understand how molecular formulas tell information about the type and quantity of atoms involved in a molecule. Lastly, we will discuss how to write a molecular formula for an ionic compound.

Polar and Nonpolar Covalent Bonds: Definitions and Examples

9. Polar and Nonpolar Covalent Bonds: Definitions and Examples

Did you know that some types of chemical bonds behave similarly to the way that children play with toys? In this lesson, you will learn about two types of bonds called polar and nonpolar covalent bonds.

How Compounds and Molecules Are Built From Elements

10. How Compounds and Molecules Are Built From Elements

Did you know that elements are somewhat like people and have different personalities? Some elements like to be left alone. Others prefer to hang out with friends. We'll discuss how elements build molecules and compounds and how these can be classified.

What Are Elements?

11. What Are Elements?

Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.

The Kinetic Molecular Theory: Properties of Solids and Liquids

12. The Kinetic Molecular Theory: Properties of Solids and Liquids

This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.
