C833 Chemistry with Lab, catalog number CHEM 5107, is the three-CU introductory chemistry course in the WGU School of Education for teachers who already hold a licence and are adding a middle grades science endorsement or a secondary endorsement in physics, biology or earth science. The audience is what makes this course distinctive. Everyone in it can already teach; what they need is enough chemistry to support a neighbouring science well, which is a different target from training a chemistry specialist.
Chemistry in service of another science
The catalog description for CHEM 5107 names the endorsements this course supports, and reading it as a list of destinations tells you how to prioritise. A biology teacher needs bonding, water, acids and bases, and energy in reactions, because those underwrite everything from protein structure to metabolism. An earth science teacher needs minerals as chemical compounds, weathering as chemistry, and the carbonate system that links oceans, rock and atmosphere. A physics teacher needs energy, states of matter and the atomic structure that connects to the electrical and thermal behaviour they already teach. A middle grades science teacher needs all of it at a shallower depth and with a far higher demand on explaining simply.
The other feature of the audience is that everyone already knows how hard it is to explain something simply without making it wrong. That is an advantage in this course and it is also a trap. The advantage is that you will instinctively reach for the accessible version. The trap is that the accessible version often contains a simplification a chemistry reviewer will not accept, such as describing electrons as orbiting like planets or treating a bond as a physical stick. Holding the accurate account and the teachable account at the same time, and knowing which simplification each teachable version carries, is the professional skill this course is really building.
What the course assesses, though, is chemistry, and reviewers are generous about your background and strict about the content. Being an experienced teacher does not substitute for particle-level explanation, and a submission that leans on classroom fluency without demonstrating the chemistry underneath is the characteristic weak submission in an endorsement course.
There is also a scheduling reality worth naming. Everyone in this course is teaching full time, which means study happens in evenings and weekends that are already partly spoken for. The competency-based structure helps here, because you are not waiting on a class to move at its own pace, but it also means nothing external paces you. Candidates who set an explicit target date for each block of content, and who put the laboratory sittings in the calendar before anything else, finish comfortably. Candidates who intend to work steadily and never schedule it tend to arrive at month five with the experiments untouched.
The most valuable habit to build is the three-level explanation: what is observed, what particles are doing, and how it is represented symbolically. Chemistry education has been organised around those three levels for decades because students who only ever meet two of them do not understand the subject. Building the habit here means it transfers directly into whatever science you actually teach.
Planning from the scoring detail
The scoring detail for your course lives in your Course of Study rather than the public catalog. Read it before planning, since a School of Education science course may be measured by a submitted performance assessment, by a proctored objective assessment, or by both, and laboratory deliverables attach to either.
Under a performance assessment, aspects are scored independently on a three-point scale and a 2 in each one passes the task. Nothing averages, so a well-run experiment does not compensate for an explanation aspect answered at the level of a definition. Head each section with the rubric's own noun.
The word budget, worked. Assume five scored aspects and directions asking for about 1,700 words alongside laboratory work. Reserve 140 for framing and 120 for a close, leaving 1,440, roughly 288 per aspect. Split each into 60 words for the observation, 120 for the particle explanation, 60 for the symbolic representation and 48 for the connection to the science you teach. That last piece is worth including even when no aspect requires it, because it is what makes the submission read as a professional adding a capability rather than a student completing a requirement.
Plan the laboratory work first in the calendar. Experiments need sittings, sittings need equipment and time, and a working teacher's evenings are the scarcest resource in the whole arrangement.
A structure that fits an introductory chemistry submission
Follow the task directions where they specify a format, including any laboratory report template. Where they leave room, this arrangement follows the three-level approach that chemistry reviewers expect.
| Section | What belongs in it | How it gets scored |
|---|---|---|
| Observation | What is seen or measured, in accurate chemical vocabulary | Scored for precision of description and correct terminology |
| Particle account | What atoms, ions or molecules are doing and which forces are involved | The scoring centre; explanations that skip this read as recall |
| Symbolic representation | Formulas, balanced equations and any calculation with the setup shown | Scored on correctness and on visible working |
| Energy | Where energy comes from or goes, in terms of bonds broken and formed | Scored where energetics are named; sign conventions checked |
| Laboratory evidence | Procedure, data, analysis and safety controls | Scored for whether conclusions follow from the data and for hazard awareness |
| Cross-science connection | How this chemistry supports the biology, earth science or physics you teach | Strengthens most submissions even where no aspect requires it |
Treat safety as part of the chemistry rather than as a preamble. You will be supervising students in a laboratory, and a reviewer preparing you for that reads every procedure with quantities, ventilation, protective equipment and disposal in mind.
Evidence craft for a teacher adding chemistry
Introductory chemistry evidence is conventional and quantitative, and its failures are predictable enough to prevent entirely.
- Show setups rather than answers, so a reviewer can award the reasoning as well as the result.
- Follow naming and formula conventions exactly, since approximate convention is simply incorrect convention.
- Carry units and significant figures consistently and state what governed the figures you kept.
- Record laboratory data as measured, never adjusted toward an expected value.
- Cite safety guidance by source where you describe a procedure, and cite external data in APA.
- Keep quotation minimal; introductory chemistry definitions are among the most reproduced text anywhere and WGU runs submissions through a similarity check.
The habit that most improves an endorsement submission is explaining at two levels at once: the chemistry as a chemist would state it, and the version you would give a student, with the simplification named. That demonstrates content mastery and teaching judgement in the same paragraph, which is exactly what an endorsement is supposed to certify.
What separates Competent from a return
Work is recorded as Competent or Not Competent, with no letter grades and no ordinary grade point average. Each aspect is judged alone, so returns identify a specific gap.
- Every scored aspect has a heading using the rubric's own wording.
- Every observation has a particle-level explanation attached.
- Every formula and equation follows convention exactly and is balanced.
- Every laboratory conclusion is traceable to recorded data.
- Every procedure describes its hazard controls.
Performance assessment work can be revised and resubmitted with no grade penalty, so a return costs calendar rather than standing. For a teacher adding an endorsement inside a six-month flat-rate term while working full time, the calendar is the binding constraint, and laboratory rework is the most expensive kind.
Where a proctored objective assessment applies, the boundary does not move. Proctored assessments are yours to sit. We prepare with concept drills, naming and equation practice and an honest readiness call, and we never ask for portal credentials.
Six mistakes candidates make in C833
- Relying on teaching experience. The course assesses chemistry, and classroom fluency is not a substitute for particle-level explanation.
- Explaining only what is observed. The particle level is where the aspects are actually scored.
- Treating conventions as details. Naming and formula errors propagate into every equation and calculation downstream.
- Scheduling laboratory work last. Experiments need sittings and repeats need more, and a working teacher has few spare evenings.
- Omitting hazard control. A reviewer preparing you to supervise students reads every procedure that way.
- Ignoring the endorsement connection. Tying the chemistry to the science you teach makes the submission stronger and the learning stick.
How support works on this course
Send your Course of Study for C833 with any rubric, task directions and laboratory templates. What comes back is a priority map that puts the chemistry your endorsement actually needs first, three-level explanations for the topics where your draft stopped at observation, a laboratory review checking that conclusions follow from data, and an aspect-mapped draft with conventions and safety in place.
Adding an endorsement while teaching is a scheduling problem as much as a chemistry problem. Front-loading the laboratory sittings and getting conventions automatic early is what makes the rest of the course fit the evenings you have.

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.
