C670 Concepts in Science, catalog number SCIE 5408, is a one-CU course covering essential science themes across chemistry, physics, biology and the geosciences. It is built for teachers who already hold a licence and are adding a science endorsement, which explains its shape: it is a bridging course, not an introduction. WGU has assumed you can already teach. What it is checking is whether the science underneath the endorsement is secure enough to teach from.
What one competency unit across four sciences actually means
The CU count on C670 misleads people in both directions. Some candidates see one CU and plan a weekend. Others see four disciplines and plan a term. Both misread it. A single competency unit signals narrow assessed scope, not narrow reading, and in a course explicitly framed around themes the assessed scope is the themes themselves rather than the content beneath them.
Themes are the operative word. Energy transfer, systems and their boundaries, structure determining function, equilibrium and change over time, scale, and the practice of evidence: these ideas recur in every one of the four disciplines on the syllabus and they are the connective tissue an endorsement course is trying to install. Photosynthesis and a nuclear reaction are both energy conversion. A cell membrane and a watershed are both systems with defined boundaries and flows across them. Enzyme shape and mineral crystal structure are both structure producing function. A candidate who holds the themes can move between the disciplines without relearning a way of thinking each time.
The practical consequence for an experienced teacher is that C670 is not a course you can clear by leaning on the subject you already know well. A biology teacher adding a general science endorsement will find the biology strand comfortable and the geoscience strand genuinely unfamiliar, and the assessment does not care which is which. Plan your time inversely to your confidence.
Sizing the work against your rubric
Scored detail for any WGU course lives inside your Course of Study rather than the public catalog. Open yours before you open anything else. Whatever your version uses, the scoring rule is constant: each aspect is scored on its own against a three-point scale and a score of 2 in every aspect is what passes a task. There is no compensation across aspects, so being strong in your own discipline earns you nothing in the three you are less sure of.
Where the course is assessed by submitted work, count the aspects and give each a heading in the rubric's own noun. Experienced teachers resist this harder than most students, because years of writing lesson narratives trains a flowing style. Competency scoring is not read that way. An evaluator holding five aspects needs to find five of them.
The word budget, worked. A one-CU course tends to carry a compact deliverable. Take a rubric with three scored aspects and directions asking for around 900 words. Reserve 80 for an opening that names the theme and the disciplines you will draw it through, and 70 to close, leaving 750 for the scored body. Three into 750 is 250 words each. Where one aspect asks you to connect a theme across more than one discipline, plan it at about 330 and fund that from the aspect that only asks you to state a concept. Stating a concept is finished in ninety words; connecting it is not.
One planning note for short deliverables. In a 900-word submission there is no room for a general introduction to science education. Every sentence has to be doing rubric work, and the paragraph you would normally use to set the scene is the paragraph that pushes a scored aspect under length.
A structure for writing about a theme across disciplines
Where the directions supply their own arrangement, follow it. Where they do not, this shape suits a thematic science submission better than the discipline-by-discipline tour most candidates reach for first.
| Section | What goes here | What it demonstrates |
|---|---|---|
| Theme stated | The unifying idea in one precise sentence, not a topic label | That you can articulate a concept rather than name a chapter |
| First discipline instance | A concrete example from one science, with the mechanism named | Content accuracy in a specific setting |
| Second discipline instance | A structurally parallel example from a different science | That the theme is genuinely general and not a coincidence of wording |
| What stays the same | The shared structure of both examples, made explicit | The integration an endorsement course is checking for |
| What differs | Scale, timescale or mechanism differences between the two | That you are reasoning rather than pattern-matching on vocabulary |
| Classroom consequence | How the theme changes what a pupil is asked to do, with the grade band named | Application, where an aspect asks for it |
| References | Standards documents, course materials and outside sources in the required style | Attribution discipline expected of a graduate submission |
The what differs row is the one candidates leave out and the one that proves the point. Energy transfer in a food web and energy transfer in a convection current share a structure and differ in almost every detail. Saying both things is the difference between an analogy and an argument.
Evidence craft for an endorsement course
An endorsement candidate writes with two audiences in mind: a science evaluator who will check accuracy, and a professional standard that expects claims about teaching to be sourced. Blurring them is the commonest weakness in submissions from experienced teachers, because classroom experience feels like evidence and reads like assertion.
- Anchor content claims in the science standards your programme uses and cite the document rather than paraphrasing from memory.
- Mark experience clearly when you use it. Writing that this works in your own classroom is legitimate if labelled as your observation and not presented as a research finding.
- Keep quantities with units and give the scale. Geological and atomic examples both fail without a stated order of magnitude.
- Choose examples you can explain fully in the space available. A half-explained nuclear process costs more than a fully explained chemical one.
- Cite outside sources in the style your directions require and keep the reference list matched to the in-text form.
- Avoid extended quotation of definitions. Restating a concept in accurate words of your own is stronger evidence of holding it.
Candidates who do well here name the boundary of the analogy they are drawing. Comparing electron shells to planetary orbits is useful and wrong past a certain point, and saying where it breaks is the kind of judgment a science endorsement is meant to certify.
What separates Competent from a return
Aspects are scored independently, and in a short deliverable that means a single under-length aspect can hold up an otherwise finished submission.
- Every scored aspect has a visible heading in the rubric's own wording, even in a document under a thousand words.
- Every discipline the aspect asks for is actually represented, not gestured at in a clause.
- Every science claim would survive review by a specialist in that discipline.
- Teaching claims are separated from content claims and sourced or labelled accordingly.
- Nothing in the submission is scene-setting. In a compact deliverable, every paragraph earns a point or comes out.
Performance assessment work at WGU can be revised and resubmitted with no grade penalty, so a return is a delay rather than a mark against you. In a six-month flat-rate term the delay is the whole cost, and it lands hardest on small courses. A one-CU course that consumes three weeks of calendar because of two rework cycles has taken time you had allocated to something four times its size.
Where C670 carries a proctored objective assessment, the boundary is absolute. Proctored exams are yours to sit. We prepare only: theme mapping across the four disciplines, targeted work on whichever strand is furthest from your own teaching subject, practice questions and an honest readiness call. We are never in the room for an assessment and never ask for portal credentials.
Five mistakes licensed teachers make in C670
- Planning by CU count. One unit describes assessed scope. Four disciplines describes the reading, and the two numbers are not related.
- Leaning on your own subject. The strand you teach is the strand that needs least attention, and it is the one candidates reread because it feels productive.
- Writing a tour instead of an argument. Four sections labelled chemistry, physics, biology and geoscience is a table of contents, not a thematic answer.
- Using experience as evidence without labelling it. Classroom observation is valuable and it is not a citation, and graduate rubrics can tell the difference.
- Spending words on introduction. Compact deliverables have no slack, and the paragraph that sets the scene is the paragraph that starves an aspect.
How support works on this course
Send your Course of Study materials plus whatever the task requires. Work comes back aspect-mapped and sized to the deliverable, with themes carried across disciplines rather than listed, content claims checked for accuracy in each strand, and teaching claims properly separated from science ones. The walkthrough explains where the argument is doing rubric work, which matters more in a short submission than in a long one.
If your version is exam-facing, the help is a theme map across the four disciplines with your weakest strand identified honestly rather than diplomatically, plus retrieval practice built on the connections rather than the vocabulary.

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
