About This Chapter
STAAR Science - Grade 8: Earth & Space - Chapter Summary
Exploring Earth and space science can be one of the most fascinating subjects for students to study. The lessons featured in this chapter are brief but intriguing to capture students' attention. Using this chapter to prepare for related questions on the STAAR Science - Grade 8 exam, students will study interesting facts about such things as the solar system, stars, the sun and the cycles of the seasons. Other relevant topics explored in this chapter include:
- Overview of the solar system, galaxy and universe
- Categorization of stars by size, color and life cycle
- Formations of planetary nebulae
- The Hertzsprung-Russell diagram
- Seasonal results of Earth's rotation and revolution
- Geography and cycles of the four seasons
- Using moon phases to predict when the moon will rise and set
- Types of tides and gravity's impact on tidal bulges
While detailed and comprehensive, the lessons in this chapter are presented in an easy-to-follow format and can be completed at each student's own pace. They can use the dashboard feature to track their progress and refer questions to expert instructors at any time. Using the multiple-choice lesson quizzes and more thorough chapter exam, students can assess their retention of the material to determine if there are any areas they need to re-examine prior to taking the STAAR Science - Grade 8 exam. They can also print the quiz worksheets and transcripts for all video lessons to use as offline study material.
1. Solar System, Galaxy, & Universe: Definitions & Difference
Want to learn what the universe, galaxy, and solar system are as well as some cool facts about each one? This lesson will give you an overview of what these three things are in a relatable fashion.
2. Solar System Overview
This lesson will go over the major aspects of our solar system, including the sun, planets, moons, asteroids, comets, meteors, meteorites, and meteoroids.
3. Stars: Definition & Facts
Before you name a star after someone, get the facts! Stars are a lot more than pretty lights up in the sky. Complete this lesson to learn more about nuclear fusion, main sequence stars, red giants, and more.
4. Types of Stars by Size, Color and Life Cycle
Learn to identify the different sizes and colors of stars and how they relate to the star life cycle. In this lesson, we'll talk about spectral classification, how many stars there are of each type and the approximate color of the different classes of stars.
5. What Are Planetary Nebulae?
This lesson will define something very cool and beautiful called a planetary nebula. You'll not only learn what it is but how it's formed, and why it produces all those amazing colors!
6. H-R Diagram: Definition & Purpose
The Hertzsprung-Russell provides important information about stars such as color, temperature and luminosity. Check out which stars are blue, hot and red, and which ones are so cool they're in a class by themselves.
7. What is the Sun? - Facts, Layers & Temperature
The sun is a big ball of gas, and it is responsible for giving us the light and heat we need to survive. Learn about the complex layers of the sun, where that energy and light originates, and the powerfully hot temperatures within our favorite star.
8. Effects of the Earth's Rotation & Revolution
This lesson explores the factors that influence seasons, daylight, and temperatures on our planet, including rotation and radiation. At the end, you can test your knowledge with a brief quiz.
9. The Cycle of the Seasons in Astronomy
This lesson will explain to you why the Earth has different seasons, what the equinoxes and solstices are, their names, and if the distance the Earth is from the Sun influences the seasons.
10. Geography of the Four Seasons
This lesson will explain how the earth's axis and rotation affect seasons. In doing this, it will also highlight the concept of the summer and winter solstices, as well as how seasons vary around the globe.
11. Moon Phases: Names & Sequence
This lesson will go over the phases of the moon. The full moon, new moon, waxing, waning, and gibbous phases and the order in which they occur and what they look like are discussed.
12. Predicting When The Moon Will Rise and Set
In this lesson, you'll learn when the moon will rise or set during four distinct phases: full moon, new moon, first quarter moon, and third quarter moon.
13. How Gravity, the Moon & the Sun Influence Tides
This lesson will define tides, the tidal force, neap tide, and spring tide. It will also talk about how the sun, moon, and Earth interact to produce tidal bulges.
