What NGSS actually asks of a lesson
The Next Generation Science Standards describe what students should be able to do with science, not just recall. Every unit in The Lab is built around the same three dimensions NGSS uses — here's what they mean and where to find them on each subject page.
Every performance expectation blends three things
Science & Engineering Practices
What scientists and engineers actually do: asking questions, planning investigations, analyzing data, using math, arguing from evidence, designing solutions.
Disciplinary Core Ideas
The content itself — organized into Physical Science (PS), Life Science (LS), Earth & Space Science (ESS), and Engineering/Technology (ETS).
Crosscutting Concepts
Ideas that repeat across every field of science: patterns, cause and effect, systems, energy and matter, structure and function, stability and change.
How to read a standard like HS-PS2-1
Breaking down the code
- HS — grade band (High School, grades 9–12). Middle school uses MS.
- PS — discipline: PS (Physical Science), LS (Life Science), ESS (Earth & Space Science), or ETS (Engineering, Technology & Applications of Science).
- 2 — core idea number within that discipline (e.g. PS2 = Motion & Stability: Forces and Interactions).
- 1 — the specific performance expectation.
Where standards live on this site
Every subject page opens with a Standards Addressed box listing the performance expectations covered by that unit's bell-ringers, lab, and simulations — so you can drop the unit straight into a pacing guide or lesson plan without re-mapping it yourself.
Standards covered across The Lab
A starting reference — each subject page goes into more depth with sub-standards and classroom context.
| Subject | High school (9–12) | Middle school (6–8) | Featured performance expectations |
|---|---|---|---|
| Physics | HS-PS2, HS-PS3, HS-PS4 | MS-PS2, MS-PS3, MS-PS4 | Forces & motion, energy transfer, wave properties |
| Chemistry | HS-PS1 | MS-PS1 | Reactions, conservation of mass, intermolecular forces & solutions |
| Biology | HS-LS2, HS-LS4 | MS-LS2 | Ecosystem dynamics, human sustainability impacts, biodiversity |
| Engineering | HS-ETS1 | MS-ETS1 | Defining problems, developing solutions, optimizing designs |
| Environmental Science | HS-ESS3 | MS-ESS3 | Resource availability, human impact, climate & Earth systems |
| Earth & Space Science | HS-ESS1, HS-ESS2 | MS-ESS1, MS-ESS2 | Earth-Sun system, energy flow and climate, water, Earth materials |
| Anatomy & Physiology | HS-LS1 | MS-LS1 | Body systems, feedback and homeostasis, cellular respiration, sensory receptors |
| Data Science | SEP 4 & 5, HS-ESS3-5, HS-LS2-1 | SEP 4, MS-LS2-1, MS-ESS3-5 | Analyzing data, computational thinking; paired with Common Core statistics standards (HSS-ID, 8.SP) |
Tip Each subject page has a High School / Middle School toggle near the top that swaps the standards, bell-ringers, project ideas, and exit tickets shown for that grade band. Labs and simulations are shared across both bands; each lab's teacher key explains how to adapt it for middle school.
NGSS practices are easier to teach with a real system
"Developing and using models," "analyzing and interpreting data," and "constructing explanations" are far easier to teach with a system students already know exists — the Detroit River, DTE's grid, the Ambassador Bridge — than with an abstract textbook scenario. Local, real data also gives students an authentic reason to argue from evidence, which is the whole point of the Science & Engineering Practices dimension.
Suggested flow for one class period
- Open with the unit's bell-ringer (5–7 min).
- Introduce the concept and the "Why Does This Matter?" Detroit connection (10 min).
- Run the simulation as guided exploration or the printed lab as hands-on practice (25–30 min).
- Close with an analysis question or preview a project idea for early finishers or extension work.
