WGU C925: Earth: Inside and Out

What C925 Is and Why It Sits in Your Science Education Program

WGU C925, Earth: Inside and Out, is an earth-science course in the School of Education, most often taken by students working toward a science-education degree or a secondary earth-science endorsement. What makes it stand out from almost everything else in your degree plan is how it is delivered: WGU offers it through a partnership with the American Museum of Natural History (AMNH) and its "Seminars on Science" program. Instead of a self-paced module you sprint through in a weekend, this is a facilitated, cohort-style course authored by working earth scientists, built around essays, videos, readings, interactive simulations, and case studies drawn from institutions like NASA and the Howard Hughes Medical Institute. You register and pay for it through WGU's normal enrollment process, not through the AMNH website.

Direct answer: You pass C925 by treating it like a paced graduate seminar, not a cram-and-test course. Keep up with the weekly readings and activities, write thoughtful discussion posts and assignments that cite the course materials, and follow the rubric closely on every submission. There is no last-minute proctored exam here; the work you produce across the weeks is the assessment.

Because it is instructor-facilitated and follows AMNH's schedule, C925 behaves differently from a typical WGU objective-assessment course. Many students appreciate the change of pace and the genuinely interesting content, but it also means you cannot accelerate past it in a day or two. Understanding that up front is half the battle.

What the Assessment Actually Involves

C925 is evaluated through a performance assessment rather than a proctored, multiple-choice objective assessment. In practice, that means your grade is built from the work you produce across the course rather than a single timed exam. Expect a combination of the following, released on a weekly rhythm:

• Weekly readings and multimedia from the AMNH course materials, which you are then asked to respond to.
• Discussion posts where you make an argument, apply a concept, and engage with classmates' responses.
• Written assignments or short analyses that ask you to synthesize course content and, often, connect it to teaching or to outside credible sources.

The content itself spans the big ideas of earth science. Topic areas for "Earth: Inside and Out" include:

• The scale and nature of geologic change over deep time.
• How scientists "read the rocks" to reconstruct Earth's history.
• Plate tectonics and the internal structure of the planet (core, mantle, crust).
• Earthquakes and volcanism, and the processes that drive them.
• Earth's interconnected systems and how they shape climate and support life.

Always confirm the exact deliverables, due dates, and grading rubric inside your own course portal, because AMNH updates its seminars and WGU aligns requirements to the current version of your program.

How Hard Is It, and How Much Time Should You Budget?

C925 is not conceptually brutal, but it is steady work. Many students report that the difficulty lives in the pacing and the writing rather than in the science being impossible to grasp. The AMNH seminar runs on a fixed schedule (commonly around six weeks), with weekly deadlines you cannot skip ahead of, so the real challenge is consistency while you juggle other courses and life.

A realistic plan is to protect a few focused hours each week for the readings, the multimedia, and drafting your posts and assignments. Students who fall behind almost always describe the same spiral: a missed week's reading makes the next discussion post shallow, which costs rubric points, which then takes more time to recover. If you stay current, most learners find C925 among the more enjoyable earth-science requirements. If you procrastinate, the fixed schedule punishes it more than a self-paced course would.

A Week-by-Week Study Approach That Fits This Course

Because C925 rewards engagement over memorization, tune your study habits to the format:

• Front-load each week's reading. Read and watch early, then let the ideas sit for a day before you write. Your discussion posts will be noticeably sharper, and sharper posts score better against participation and quality criteria.
• Use active recall on the vocabulary. Terms like subduction, stratigraphy, convection, and deep time recur constantly. Make a running glossary and quiz yourself instead of re-reading; being able to explain a term in your own words is exactly what the written work demands.
• Apply spaced repetition to the big models. Revisit the plate-tectonics framework and the rock cycle across multiple weeks rather than once. These are the connective threads the later assignments assume you already own.
• Practice by writing to the rubric. Before you submit anything, reread the rubric and check each criterion against your draft. Treat that comparison as your "practice test" for this course, since there is no separate quiz to rehearse on.
• Cite the course materials directly. Assignments and posts that reference specific readings, videos, or case studies read as evidence-based; vague opinion posts lose easy points.

If you find the science background thin, pairing this with the reasoning habits you build in other School of Education science courses helps. Guides like C659 Conceptual Physics, C736 Evolution, and C888 Molecular and Cellular Biology lean on the same skills of reading scientific explanations and applying models, and reviewing them can strengthen how you interpret C925's material.

Mistakes That Cost Students Points in C925

• Treating it like a self-paced course. Trying to "binge" a facilitated seminar backfires; the weekly structure and discussion component require you to be present over time.
• Thin discussion posts. One-line agreements with classmates rarely satisfy quality expectations. Add a concept, an example, or a citation.
• Ignoring the rubric until the end. Students who write first and check criteria last routinely miss a requirement and have to redo work.
• Skipping the multimedia. The videos and case studies are not filler; assignments often draw directly from them.
• Waiting on feedback. Because a person facilitates the course, turnaround is not instant. Submit early enough to absorb comments before the next deadline.

C925 Readiness Checklist

Before you consider yourself ready to move confidently through C925, ask whether you can honestly answer yes to each of these:

• Can you explain plate tectonics and name the evidence that supports it?
• Can you describe how geologists use rock layers to reconstruct Earth's history?
• Can you connect earthquakes and volcanoes to the underlying plate processes that cause them?
• Can you define deep time and explain why the scale of geologic change matters?
• Can you describe how Earth's systems interact to shape climate and support life?
• Can you write a discussion post that makes a claim and backs it with a course source?
• Can you map each rubric criterion to a specific part of your draft before submitting?
• Have you scheduled protected weekly time so no reading or deadline slips?

FAQ

Is WGU C925 an OA or a PA?

C925 is assessed through performance-based work, not a proctored objective assessment. Your evaluation comes from weekly assignments, discussion posts, and written analyses completed across the course rather than a single timed exam. Confirm the exact requirements in your course portal, since they follow the current version of your program.

Why is C925 delivered differently from my other WGU courses?

It runs through WGU's partnership with the American Museum of Natural History's Seminars on Science. That means a facilitated, scheduled seminar authored by working scientists, rather than the fully self-paced format you may be used to elsewhere in your degree. You still enroll through WGU rather than the AMNH site.

How long does C925 take?

The AMNH seminar is built around a fixed multi-week schedule (commonly about six weeks) with weekly deadlines. Because it is paced, you generally cannot accelerate through it the way you might a self-paced course, so plan for steady weekly effort.

Is C925 hard?

Many students report that the science is approachable but the course demands consistency and solid writing. The difficulty is usually about keeping up with weekly reading and producing thoughtful, evidence-based posts, not about the concepts being unreachable.

What topics should I focus on most?

Prioritize plate tectonics, the internal structure of Earth, how rocks record geologic history, the drivers of earthquakes and volcanoes, and how Earth's systems interact over deep time. These themes recur throughout the assignments.

How many competency units is C925 worth?

WGU assigns competency units per course, but the exact CU value for C925 depends on your specific program version, and it is best confirmed on your official Degree Plan or in the current WGU Institutional Catalog rather than relying on secondhand figures.
