Michigan Merit Exam: History of the Earth Chapter Objectives

The Michigan Department of Education uses the Michigan Merit Exam (MME) to measure the academic achievement of its 11th-grade students in the spring of each year. The MME is an umbrella term for a series of tests given over an eight-week window. This chapter is meant to prepare you for one of these assessments, the computer-based M-Step test. The untimed M-Step science session is estimated to take close to an hour to complete.

What is the Age of the Solar System?

1. What is the Age of the Solar System?

This lesson will tell you how old our solar system is and how we know that's the case thanks to radioactive decay, isotopes, half-life, and the solar nebula.

Four Stages of Planetary Development

2. Four Stages of Planetary Development

This lesson will describe the four stage of planetary development. They are, from past to present, differentiation, cratering, flooding, and slow surface evolution.

Formation of the Earth: Theories

3. Formation of the Earth: Theories

In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.

The Atmosphere on Earth

4. The Atmosphere on Earth

This lesson describes the evolution of the Earth's atmosphere, from its ancient past to the present day to how it's being changed by humans today. You'll learn about how outgassing, photosynthesis, and oceans all played a role in its formation, what air is composed of, and the real effect of human pollution on our changing atmosphere.

The Origin of Life on Earth: Theories and Explanations

5. The Origin of Life on Earth: Theories and Explanations

Ever wonder how living things came from non-living things? We will explore what conditions on early Earth may have created life from non-living items.

Geologic Time Scale: Major Eons, Eras, Periods and Epochs

6. Geologic Time Scale: Major Eons, Eras, Periods and Epochs

The geologic time scale is an essential tool for understanding the history of Earth and the evolution of life. In this lesson, explore the principal eons, eras, periods, and epochs that help us track major events in geologic history.

The History of Life on Earth: Timeline and Characteristics of Major Eras

7. The History of Life on Earth: Timeline and Characteristics of Major Eras

The Earth is over 4 billion years old. Ever wonder what happened during certain time periods in that large amount of time? We will look at the major eons and eras of Earth's history along with important characteristics of each.

Relative Dating with Fossils: Index Fossils as Indicators of Time

8. Relative Dating with Fossils: Index Fossils as Indicators of Time

You may already know how to date a fossil with a rock. But did you know that we can also date a rock with a fossil? Watch this video to find out how we use index fossils to establish the relative ages of rocks.
