About This Chapter
Organization of Matter - Chapter Summary
Are you having a difficult time recalling the organization of matter, as in the elements of matter and related terminology? Well then, this chapter is for you. The connected lessons walk you through the different characteristics of matter, including the building blocks of matter and how changes in matter occur. Once you reach the end of this chapter, you should feel far more confident about answering questions related to the following:
- Defining elements and exploring their functions
- Establishing how elements are used to build molecules and compounds
- Providing examples of heterogeneous mixtures
- Developing working definitions for ions, molecules, and atoms
- Describing the characteristics and mass of a subatomic particle
- Explaining how matter changes through four different states
It may have been a while since you have looked over these basic science lessons, so it shouldn't be surprising if you are a little rusty on the terms and details. All you need is a review, and this chapter will give you a thorough recap concerning the organization of matter. When watching a lesson, feel free to pause at any time, rewind, or use the timeline feature to skip to different topics. You can move through the lessons in the order in which they are presented, or you can pick specific lessons based on your study needs.
While relearning this information can be fun, you want to make sure that you are getting the most out of your study time. To assess your progress, we offer you quizzes for each lesson as well as a chapter exam. Both the quizzes and exams use multiple-choice questions. After you provide your answers, an answer key will appear on screen, and the key will give you an explanation for each correct answer. If you don't pass the first time, go back over the lessons until you get 100% on every quiz and exam.
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.
2. 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.
3. Heterogeneous Mixture: Definition & Examples
You come into contact with mixtures every day. Most of the foods we eat and drink are some form of mixtures. In this lesson, you will learn about heterogeneous mixtures and the types of heterogeneous mixtures recognized by scientists.
4. What Is an Ion?
Learn what an ion is and how it forms. We will look at some common ions and get to know the terms for the two types of ions. Take the quiz at the end to see how well you understand the lesson.
5. What is a Molecule? - Structure & Models
Water is a molecule. Caffeine is a molecule. DNA is a (really big) molecule. Learn how molecules are constructed and modeled and explore the different types of models.
6. 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?
7. What Is a Subatomic Particle? - Definition & Mass
A subatomic particle is a particle smaller than an atom. Learn more about how to identify subatomic particles through several examples, and test your knowledge with quiz questions.
8. 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.
