Physics A is the first semester of a full-year laboratory physics course submitted under UC A-G area D (laboratory science). Reviewers look for three things, and you should be able to point to each in the course.

1. Standards and depth. The semester is built on the California NGSS performance expectations HS-PS2-1 to HS-PS2-6 and the four engineering-design expectations HS-ETS1-1 to HS-ETS1-4, with RST.11-12 literacy and the Mathematical Practices. Physics B carries energy (HS-PS3), waves (HS-PS4) and the electromagnetic parts of HS-PS2-4 and HS-PS2-5. The validator checks that every expectation is cited across the full year, and the table below shows where each lands in this semester. The course is quantitative: students linearize data, resolve vectors with sine and cosine, fit lines and derive orbital speed from two laws. That is what separates it from the conceptual Physical Science course.

2. Hands-on laboratory work. UC’s area D guidance expects hands-on laboratory activity that is directly connected to the rest of the course and that takes a substantial share of class time; the articulation checklist for this course plans for at least 20% of instructional time. Check the current A-G Guide wording when you submit. Every unit’s Investigation Lab (x.2) is a hands-on lab with measured data, and several other lessons carry second labs: the marble launch (1.4), the friction mini-lab (2.3), the egg crash-test cart (3.4) and the whirling stopper (4.1). A PhET simulation never counts as the lab; it is a modeling tool or the alternative route for a student who cannot be there.

3. Evidence of scientific practice. Every lab report asks for a claim, evidence and reasoning, a quantitative uncertainty and a discussion of error. Every culminating task moves through a separately scored plan, a peer-reviewed draft, a revised final and a presentation or defense. Keep one set of student work from each stage; if UC asks for samples, those are what you send.

What reviewers push back on. Labs that are demonstrations, labs whose data are never analyzed, and “labs” run entirely in a simulator. If a unit runs short on time, cut a worked example, never the lab.
