About This Chapter
MTLE Middle Level Science: Properties & Structure of Matter - Chapter Summary
The lessons in this chapter will provide you with an in-depth review of matter, including its various states and molecular structures. By the end of this chapter, you will have examined:
- Physical and chemical properties of matter
- Suspension, solubility and solubility curves
- Techniques for separating mixtures
- Particles and subatomic particles
- Kinetic theory of matter
- The Periodic table
- Atomic and ionic radii
- Energy of ions
- Nuclear chemistry concepts and radioactive decay
Each lesson has been developed to provide you with several methods for learning. You will find a short video included that will help visually illustrate the material. The video's transcript is also included as a resource for taking notes. You can take a self-assessment quiz at the end of each lesson to apply what you've learned. If you think you need to review a section of the lesson again, use the timeline below the video for easy navigation.
MTLE Middle Level Science: Properties & Structure of Matter - Objectives
The MTLE Middle Level Science exam is a requirement for educators in Minnesota hoping to obtain certification to teach middle school science courses. The exam is comprised of two subtests, and each of the subtests cover two main areas of content. The material you'll review in this chapter will prepare you for questions related to physical science on Subtest 2. Physical science questions account for 55% of the total score of Subtest 2.
Each of the MTLE Middle Level Science exam subtests contain approximately 50 multiple-choice questions. You can take both subtests on the same day or take them on separate occasions. You will have one hour to complete each subtest, and you'll need a score of 240 or higher on each subtest in order to qualify for certification.
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.
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.
3. What is Suspension in Science? - Definition, Types & Examples
Have you ever seen dust particles floating in a stream of sunlight? The dust you see in the air is an example of suspension. Discover this fascinating mixture, explore a special type of suspension, and see examples in this lesson.
4. Solubility and Solubility Curves
Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.
5. Colloids: Definition, Types & Examples
In this lesson, you will learn the definition of colloids. There will be examples provided to assist you with your understanding of the topic. Also, several types of colloid solutions are provided.
6. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
7. What is a Particle? - Definition & Theory
Particles are fundamental entities that are used by scientists to explain different types of phenomena. Learn more about them, subsequently testing your knowledge with a quiz.
8. 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.
9. The Kinetic Theory of Matter: Definition & The Four States of Matter
Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.
10. 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.
11. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table
Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.
12. Ionization Energy: Trends Among Groups and Periods of the Periodic Table
Do you know someone who has undergone radiation as a form of cancer treatment? Have you ever thought about why X-rays have health risks? Watch the video to find out what these types of radiation are really doing to atoms, define ionization energy and identify ionization trends on the periodic table.
13. Covalent Bonds: Predicting Bond Polarity and Ionic Character
Learn about covalent bonds and their two types: nonpolar covalent bonds and polar covalent bonds. Discover how to predict the type of bond that will form based on the periodic table. Learn what ionic character means and how to determine it.
14. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry
What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
15. Radioactive Decay: Definition, Formula & Types
In this lesson, we'll discuss radioactive decay and learn the terms parent nucleus, daughter nucleus, and half-life. We'll also examine three types of radioactive decay.
