Ch 21: MTLE Elementary Education: Life Science

About This Chapter

The lessons in this chapter will help you prepare for the MTLE Elementary Education exam by reviewing a variety of life science concepts. Take the self-assessment quizzes to test your knowledge.

MTLE Elementary Education: Life Science - Chapter Objectives

Use the lessons in this chapter to examine living organisms and how they interact with the environment. The information you review will help you answer questions related to science on the MTLE Elementary Education exam. After completing this chapter you will have reviewed:

  • Characteristics of living organisms
  • Organisms' basic needs
  • Classification of plants
  • Vertebrates
  • Life cycles
  • Genetics
  • Human immune system
  • Ecosystems
  • Animal behavior
  • Human impact on animal species
  • Invasive species

The lessons in this chapter have been designed to cover all of the material regarding life sciences that you will need to review to prepare for the MTLE Elementary Education exam. To aid in the learning process, each lesson contains a short video to help illustrate the information. You'll find the transcript of the video included as a great resource for taking notes. You can take a self-assessment quiz at end of each lesson to apply what you've learned and practice for the exam.

MTLE Elementary Education: Life Science - Objectives

The MTLE Elementary Education exam is administered to educators in Minnesota who are hoping to attain certification to teach at the elementary level. The exam is comprised of three subtests and each subtest covers two main areas of content. The material reviewed in this chapter prepares you for the science portion of Subtest 3. Questions related to this content area account for 57% of Subtest 3's final score.

The MTLE Elementary Education exam's three subtests each contain about 50 multiple-choice questions. You will have one hour to complete each subtest. You can take the subtests all on the same day or complete them on separate occasions. You will need a score of 240 or higher on each subtest to qualify for certification.

The Defining Characteristics of Living Organisms

1. The Defining Characteristics of Living Organisms

A house is not a living thing, but the people, animals, and plants living inside it are. So how do we define 'life'? Learn about seven characteristics that all living organisms have in common, no matter how different they may look on the outside.

Living Organisms: Basic Needs

2. Living Organisms: Basic Needs

There are many types of living organisms on Earth. But what makes us all the same is our basic needs for survival, which is a shorter list than you might think!

What are the Parts of a Plant?

3. What are the Parts of a Plant?

Ever look at a plant and wonder what each specific part is? A plant has two basic plant parts: the shoot and root systems. In this lesson, you'll learn and be able to identify each individual plant part within the shoot and root systems.

Classification of Vascular, Nonvascular, Monocot & Dicot Plants

4. Classification of Vascular, Nonvascular, Monocot & Dicot Plants

Plants may not seem like the most interesting things around, but they are definitely useful. In this lesson, we will explore the basic classification of plants and the unique characteristics of each group.

Vertebrates: Definition, Features & Classification

5. Vertebrates: Definition, Features & Classification

Vertebrates are an interesting collection of animals, including humans, that have evolved over millions of years. Birds, reptiles, amphibians, mammals and even fish are included in the vertebrate category. Find out more here!

What is a Life Cycle? - Definition, Stages & Examples

6. What is a Life Cycle? - Definition, Stages & Examples

In this lesson, you'll learn the definition of 'life cycle' and find out about the three basic stages of a life cycle. You'll also explore examples of different life cycles.

Genetic Variability and Random Mutation

7. Genetic Variability and Random Mutation

Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.

How the Human Immune System Works

8. How the Human Immune System Works

Your immune system protects you against microorganisms that could make you sick. It is made up of an army of white blood cells that work together to recognize and destroy the bad guys. Learn how your immune system and immunizations work.

Ecosystems, Habitats and Ecological Niches

9. Ecosystems, Habitats and Ecological Niches

Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.

Animal Behavior: Innate vs. Learned

10. Animal Behavior: Innate vs. Learned

There are some things that animals are born knowing how to do. These behaviors are innate. They are different than learned behaviors, which an animal must pick up through training, observation or experience. Learn more about these types of behaviors.

Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

11. Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction

In this lesson you will learn about two ways humans contribute to species extinction. We break up habitats by building roads and clearing land, and we pollute both land and water. You will also learn about the specific terms used to describe the processes, habitat fragmentation and anthropogenic pollution.

What Is an Invasive Species? - Definition, List & Effects

12. What Is an Invasive Species? - Definition, List & Effects

This lesson focuses on a group of organisms called invasive species. You'll learn what makes a species invasive and see some examples of invasive species. You'll also discover why invasive species are considered a problem and explore the impacts they have on the environment, the economy and on humans.
