Ch 37: CEOE Middle Level Science: Properties of Matter

About This Chapter

Your Certification Examinations for Oklahoma Educators (CEOE) for Middle Level Science will be so much easier using the prep tools in this chapter. The information in these lessons is on the subject of the properties of matter.

CEOE Middle Level Science: Properties of Matter - Chapter Summary

Prepare for recognition and understanding of the characteristics of matter when our subject matter experts walk you through these lessons on the properties of matter. They'll serve as a great study resource as you get ready for the CEOE Middle Level Science exam. Our experts go over such topics as:

  • Defining elements
  • The meanings of atomic number and mass number
  • Elements as the building blocks of compounds and molecules
  • Melting, freezing, condensation, evaporation, sublimation and deposition
  • Everyday chemical reactions
  • The definition of nuclear reaction and examples
  • Radioactive decay and decay graphs
  • The nitrogen and the carbon cycles of matter

Engaging video lessons are a few minutes long. We provide the corresponding written transcript for your convenience. There is also a video timeline that is marked by keywords that allows you to go right to any section you might want to review. Your study and review experience will be much more enjoyable with our prep help.

What Are Elements?

1. 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.

Atomic Number and Mass Number

2. Atomic Number and Mass Number

Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.

How Compounds and Molecules Are Built From Elements

3. How Compounds and Molecules Are Built From Elements

Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.

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

4. 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.

Common Chemical Reactions and Energy Change

5. 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.

Nuclear Reaction: Definition & Examples

6. 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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

7. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

8. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
