Ch 16: ILTS Environmental Science: Objects in the Universe

About This Chapter

Let this chapter show you about the dynamic interaction of objects in the universe. The video lessons and self-assessment quizzes will prepare you to correctly respond to these types of questions on the ILTS Environmental Science exam.

ILTS Environmental Science: Objects in the Universe - Chapter Summary

This chapter's lessons examine the objects in the universe, both within and outside of our solar system. You will get an overview of how objects in the solar system move and relate to each other, as well as a look at structures farther away. Other lessons cover the origins of the universe itself and the development of objects, including the moon. The videos cover these topics that will prepare you for the exam questions:

  • Structure of the sun and its life cycle
  • Life cycle of black holes
  • Characteristics of asteroids, meteorites and comets
  • Radio, reflecting and refracting telescopes
  • The big bang theory
  • Star formation
  • Dwarf planets
  • Predictors of life on other planets

You'll be taught by experienced instructors who know how to make learning fun while giving you the knowledge you need. At the end of this chapter, you will be prepared for exam questions on the universe and its objects.

Objectives of the ILTS Environmental Science: Objects in the Universe Course

Illinois requires that individuals who want to teach environmental science at the secondary school level pass the Illinois Licensure Testing System (ILTS) environmental science content area exam. With 125 multiple-choice questions, this exam is divided into six subareas. The questions on the objects of the universe and their dynamic interactions are part of subarea IV. You can prepare for the ILTS exam by taking the self-assessment quizzes found at the end of each video lesson. The quizzes will allow you to become familiar with the format and also assess your knowledge of the subject.

Structure of the Sun

1. Structure of the Sun

Discover the layers of the sun, including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Find out which layers you can see from Earth. Investigate what sunspots and solar flares are.

Life Cycle of Black Holes

2. Life Cycle of Black Holes

Learn about black holes, their myths and their reality. Learn how black holes form after stars undergo supernovae and create singularities. Discover how big black holes grow, how scientists find black holes and where black holes are located in the universe.

Asteroids, Meteorites & Comets: Definitions and Characteristics

3. Asteroids, Meteorites & Comets: Definitions and Characteristics

This lesson will cover the definitions and characteristics of asteroids, comets and meteorites. It will also explore what impact they have had on Earth and the impact they might have in the future.

Types of Telescopes: Radio, Reflecting & Refracting Telescopes

4. Types of Telescopes: Radio, Reflecting & Refracting Telescopes

Learn about the different types of telescopes that astronomers use: X-ray, radio, gamma ray, reflecting and refracting. Learn what the differences are between them and what different things they show us about the universe.

Evidence for the Big Bang Theory: Background Radiation, Red-Shift and Expansion

5. Evidence for the Big Bang Theory: Background Radiation, Red-Shift and Expansion

Discover what evidence exists to support the Big Bang theory of the birth of the universe. Learn how cosmic background radiation, the red shift of light and the ongoing expansion of the universe led scientists to believe that the universe was started with the Big Bang.

Formation of the Moon: Theories

6. Formation of the Moon: Theories

Explore the four major theories on the formation of the Moon. The theories include the fission theory, capture theory, condensation theory and giant impact theory. Also look at both information supporting and flaws found in these theories.

Planetary Predictors of Extraterrestrial Life

7. Planetary Predictors of Extraterrestrial Life

Investigate what is needed for life to exist anywhere and the implications for life in our solar system beyond Earth. Consider Mars and some of the moons of Jupiter and Saturn, including Europa, Callisto, Ganymede and Enceladus.

Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune

8. Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune

Take a tour of the outer planets of our solar system: Jupiter, Saturn, Uranus, and Neptune. Find out what makes each of these gas giants unique and learn about Pluto, a dwarf planet.

Star Formation: Main Sequence, Dwarf & Giant Stars

9. Star Formation: Main Sequence, Dwarf & Giant Stars

Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.

Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres

10. Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres

Discover why Pluto had to leave the league of planets and was downgraded to a dwarf planet. Learn the definitions for planet and dwarf planet. Find out about the currently classified dwarf planets in our solar system: Pluto, Eris, Ceres, Haumea and Makemake.

Formation of the Earth: Theories

11. 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.

Inner Planets of the Solar System: Mercury, Venus, Earth & Mars

12. Inner Planets of the Solar System: Mercury, Venus, Earth & Mars

Take a tour of the four inner planets: Mercury, Venus, Earth and Mars. Known as the terrestrial planets, find out what makes each of them unique and how they are different from the outer planets, the gas giants.

Stages of the Sun's Life Cycle

13. Stages of the Sun's Life Cycle

Discover our sun, the provider of energy for life on Earth. Learn how the sun was born, how it lives as a main sequence star, how it will age into a red giant and how it will die as a white dwarf.

Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

14. Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

This lesson explains how galaxies form, starting with the Big Bang. You'll also learn about the solar nebula hypothesis and three galaxy types, including spiral, elliptical, and irregular galaxies.
