C833 gives licensed teachers who are adding a science endorsement a working foundation in chemistry, with hands-on labs.
WGU describes it as an introduction to chemistry for already licensed teachers seeking an additional license or endorsement in middle grades science or in secondary physics, biological science or earth science.
It is designed for those not majoring in chemistry education and shows how chemistry applies across other branches of science. WGU lists Concepts in Science as a prerequisite.
The challenge for many teachers is time and confidence. Chemistry builds quickly: if naming compounds or moles are shaky, balancing reactions and stoichiometry feel impossible.

Key Concepts Explained
Balancing Equations
Atoms are neither created nor destroyed in a reaction, so each element must appear in equal numbers on both sides. Balance with coefficients, never by changing subscripts.
Example: Methane burns: CH4 + O2 → CO2 + H2O. Carbon is balanced. Four hydrogens need 2 H2O. Now there are 4 oxygen atoms on the right (2 in CO2, 2 in water), so use 2 O2. Balanced: CH4 + 2O2 → CO2 + 2H2O.
The Mole and Stoichiometry
A mole is a counting unit that links mass to number of particles. Molar mass converts grams to moles; coefficients give the mole ratio between substances.
Example: How much water forms from 16 g of methane? Methane's molar mass is about 16 g/mol, so 16 g is 1 mol. The ratio is 1 CH4 to 2 H2O, so 2 mol of water form, about 36 g.
Periodic Trends
Atomic radius generally decreases across a period and increases down a group. Ionisation energy follows the opposite pattern. These trends explain why sodium reacts readily and why fluorine attracts electrons strongly.
Connecting C833 to Your Classroom
Because C833 is written for teachers of other sciences, the chemistry is meant to travel. Biology teachers meet it in enzymes, cellular respiration and pH. Earth science teachers meet it in minerals, weathering and ocean chemistry. Physics teachers meet it in energy changes and the structure of matter.
Making those links while you study helps in two ways. It gives the abstract topics a purpose, and it prepares you for explanation tasks, which usually reward accurate particle-level reasoning in plain language.
Example: Why does a puddle evaporate on a cool day? At particle level, molecules at the surface have a range of energies. Some have enough energy to overcome the attractions holding them in the liquid and escape as gas. Wind removes them before they can return, so evaporation continues below boiling point.
Typical Assignments and How to Approach Them
WGU states that the science programs use a home lab kit for experiments. Check your course page for current tasks. Work in this subject typically includes:
| Task type | What it tests | How to approach it |
|---|---|---|
| Lab report | Method, data and reasoning | Record raw data first, then calculate and explain errors |
| Problem sets | Equations, moles, naming | Show units at every step |
| Concept explanation | Understanding, not recall | Explain at particle level, with a diagram if allowed |
| Safety analysis | Lab safety practice | Link each hazard to a control measure |
Where Students Get Stuck
- Units. Losing track of grams, moles and liters causes most calculation errors.
- Changing subscripts. This changes the substance. Only coefficients balance an equation.
- Error analysis. "Human error" is not an explanation. Name the specific source and its likely effect.
- Rushing the labs. Read the whole procedure and safety notes before opening the kit.
Study Tips for C833
- Practice naming and formulas daily for a week; everything else depends on them.
- Keep a lab notebook with dates, raw data and observations as you go.
- Explain each concept as you would to your own students; gaps show quickly.
- Use the periodic table actively, predicting trends before checking them.
How We Help with C833
Send the lab instructions, your data, the rubric and any evaluator comments. A chemistry tutor explains the calculations, checks your reasoning, or models a lab report structure you can follow. Our lab report guide covers the general format.
GradeEssays is independent of Western Governors University. We never invent or alter lab data: your results must come from your own experiments. Use our help to understand the chemistry, then write and submit your own work under WGU's academic integrity rules. Every order is written from scratch, with free revisions within the scope of your original request.

Frequently Asked Questions
WGU designs it for licensed teachers seeking an additional license or endorsement in middle grades science or secondary physics, biology or earth science, who are not majoring in chemistry education.
WGU lists Concepts in Science as the prerequisite.
Yes. WGU's description includes laboratory experiences, and its science programs supply a home lab kit.
We can explain the chemistry and show a model structure, but your data and final report must be your own work.
Most students find stoichiometry hardest, usually because of weak unit handling. Practice conversions until they are automatic.
No. We are independent and not connected with Western Governors University.
