Astronomy takes future Earth Science teachers from stellar spectra to Kepler's laws — the astronomical content knowledge that underpins the secondary Earth Science curriculum.
What D852 covers
The course explores the fundamental principles of the universe, focusing on the lifecycle of stars, the structure of our solar system, and the dynamics of the Sun-Earth-Moon system. Students learn about the analysis of starlight spectra and brightness to determine the composition, movement, and distance of stars.
Kepler's laws are examined to explain the motions of orbiting celestial bodies, and students learn how cyclical changes in Earth's orbit and axial orientation affect climate over geological time scales, building on geological knowledge by studying extraterrestrial objects such as lunar rocks and meteorites.
The D852 performance assessment
Expect a performance assessment requiring you to analyze astronomical data (e.g., starlight spectra) or apply Kepler's laws to explain a celestial phenomenon.
Key topics in D852
- Stellar lifecycle and spectra analysis
- Kepler's laws
- Sun-Earth-Moon system dynamics
- Earth's orbital cycles and climate
Writing tips for D852
Follow the task instructions and rubric line by line
WGU performance assessments for D852 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.
Ground every claim in a specific secondary grade level and science content
Secondary Science Education courses like D852 typically ask you to apply content knowledge and pedagogy to a specific grade level and science topic rather than write about teaching in the abstract. Evaluators are checking whether your reasoning fits that concrete classroom situation — vague, generic statements about "good science teaching" usually lose rubric points for lacking that specificity.
Because WGU is self-paced, don't let "no deadline pressure" become no submission
There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for each D852 assessment as a real deadline.

Why students seek help with D852
Candidates sometimes describe astronomical phenomena qualitatively without the quantitative analysis (spectra, orbital mechanics) the course specifically requires — the rubric typically wants genuine data analysis, not description alone.
