High School Science
High school science lesson plans
High school science teachers juggle lab safety, deep content, and students who need support reading data.
Time-poor planning makes it hard to align phenomena, lab routines, and evidence-based reasoning.
Last-period labs still need setup, cleanup, and analysis in one block.
Assessment pressure grows when lab time, discussion, and CER writing compete for minutes.

Common planning constraints
Factors that shape lesson planning for high school science.
Behavior & safety
Labs need clear procedures, predictable transitions, and visible safety checks.
Differentiation
Tiered data tables and vocabulary supports help mixed-ability classes interpret results.
Pacing
Setups, investigations, and analysis must fit within a single lab block.
Assessment
Claims, evidence, and reasoning need to be captured before cleanup starts.
How LessonCraft helps
- Outlines a predictable flow: phenomenon, investigation, analysis, and explanation.
- Adds pacing guidance for setup, lab time, and cleanup so the lesson stays on track.
- Flags differentiation moves like scaffolded CER stems and data supports.
- Builds in formative checks for evidence use and lab reflections.
Example lesson
Sample topic
Rates of reaction lab
LessonCraft organizes the lab with a short demo, student investigation, and a data discussion that links to collision theory.
Available formats:
- Tournament: teams compare reaction rate graphs and defend conclusions.
- Structured: guided lab with checkpoints after each trial.
- Discussion: students debate which variables matter most using CER prompts.
