Integrated Physical Sciences gives students across dozens of WGU degrees a unified view of physics, chemistry, and Earth science, grounded in everyday application.
What C165 covers
The course provides students with an overview of the basic principles and unifying ideas of the physical sciences: physics, chemistry, and earth sciences. Course materials focus on scientific reasoning and practical, everyday applications of physical science concepts to help students integrate conceptual knowledge with practical skills.
The C165 performance assessment
Expect a performance assessment requiring you to apply a physical science principle to a real-world, practical scenario.
Key topics in C165
- Unifying principles across physics, chemistry, and Earth science
- Scientific reasoning
- Practical, everyday science applications
Writing tips for C165
Follow the task instructions and rubric line by line
WGU performance assessments for C165 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.
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 the C165 assessment as a real deadline.
Follow the required lab-report or investigation structure precisely
Science courses like C165 are typically assessed on a specific report structure (hypothesis, method, data, conclusion). Evaluators check whether that structure is followed exactly, not just whether the science content is accurate.

Why students seek help with C165
Students sometimes explain a physical science concept in purely theoretical terms without the practical, everyday-application connection the course specifically emphasizes.
