About This Chapter

Let us guide you through your preparations for the Ohio Graduation Test (OGT) with this in-depth look at matter. Boost your understanding by reviewing engaging video lessons, then test your knowledge with self-assessment quizzes.

Ohio Graduation Test: Understanding Matter - Chapter Summary

The lessons in this chapter can help you better understand matter and increase your chances of success on the Ohio Graduation Test. Upon completion of this chapter, you could be ready to:

  • Describe the physical and chemical properties of matter
  • Explain states of matter and chemical versus physical changes
  • Classify substances according to physical properties
  • Share how compounds and molecules are built from elements
  • Define the atom, atomic number, mass number and the electron shell
  • Discuss properties of groups and periods of the periodic table
  • Provide details about covalent and ionic chemical bonds

This chapter compiles the materials you need to study for your test, including quizzes, transcripts and an interactive ask-an-expert section. Your only jobs are to make use of the tools and absorb the information. Review the lessons from the comfort and convenience of your home, or study while on-the-go via your mobile devices.

Ohio Graduation Test: Understanding Matter Chapter Objectives

Students must take and pass Ohio Graduation Tests to secure their high school diplomas in the state. There are five OGT tests that cover writing, math, reading, social studies and science. Each test requires a passing score of at least 400. Success on the tests ensures administrators and parents that students can perform well in college and the workplace.

Topics in this chapter on understanding matter are found on the science portion of the OGT. This test consists of 32 multiple-choice questions, four short-answer questions and two extended-response questions. The test measures student achievement related to 6 academic standards that include life sciences, physical sciences, earth and space science, technology, ways of knowing and scientific inquiry. Prepare for this test by reviewing the comprehensive lessons in this chapter. You can take short quizzes and a chapter exam to test your comprehension.

Matter: Physical and Chemical Properties

1. Matter: Physical and Chemical Properties

How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.

States of Matter and Chemical Versus Physical Changes to Matter

2. States of Matter and Chemical Versus Physical Changes to Matter

The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.

Classifying Substances by Their Physical Properties

3. Classifying Substances by Their Physical Properties

After watching this video, you will be able to explain what physical properties are and use them to classify some common substances. A short quiz will follow.

How Compounds and Molecules Are Built From Elements

4. 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.

The Atom

5. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

Atomic Number and Mass Number

6. 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.

The Electron Shell

7. The Electron Shell

You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?

The Periodic Table: Properties of Groups and Periods

8. The Periodic Table: Properties of Groups and Periods

How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.

Chemical Bonds I: Covalent

9. Chemical Bonds I: Covalent

Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.

Chemical Bonds II: Ionic

10. Chemical Bonds II: Ionic

Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.
