Earth and Space Science is organized by content themes and further broken down into topics. The content themes represent a unit of study and are shown below:
Themes
- Introduction to Earth and Space Science
- The Universe
- The Solar System
- Earth and the Universe
- Earth's Surface Processes and Spheres
- Rocks and Minerals
- Geologic History
- Plate Tectonics and Earth's Interior
- Weather and Climate
- Earth's Resources
Topics
Each theme contains a range of specific topics. For example, here are some topics within The Universe.
- The Big Bang Theory
- Stars
- Galaxies
Subtopics
Each topic contains two subtopics that categorize questions into their designated skill level types. The two subtopics used in Earth and Space Science are below:
Assessments
In addition to our practice guide, Earth and Space Science includes diagnostic exams, topic quizzes, and simulations that include questions unique from those on our practice guide. Diagnostic exams are designed as "pre-tests" assessing prior knowledge and skill while topic quizzes are short review assessments over major ideas found within the themes. Simulations are virtual labs that have accompanying auto-graded and short-response questions.
Free Response Questions
Earth and Space Science includes free-response questions in the form of classroom sample tasks. Classroom sample tasks are written response assignments that are rooted in real-world scenarios and assess both scientific content and skill.
