Lab skills
The measuring, calculating and reporting skills that show up in almost every lab, from reading a graduated cylinder to writing the report.
Percent error
Learn how to calculate percent error with a worked density example, the correct formula, rounding guidance, and how to interpret a result above or below the accepted value.
Density
Calculate density with a graduated-cylinder example, compare measurement methods, convert mL to cm^3, and spot limits in displacement readings.
Graduated cylinder
Why liquid curves in a cylinder, how to read the bottom of that curve correctly, and how far to estimate past the marked lines.
Triple beam balance
How a triple beam balance works, the order to slide the riders in, and how to add the three beam readings together.
Metric conversion
Convert metric lab measurements with factor-label steps, prefix and unit tables, worked examples and checks for scientific notation and rounding.
Significant figures
The rules for counting significant figures, why they matter for lab reports, and a worked example of rounding a calculated answer.
Lab safety
Review lab safety rules, hazard symbols, PPE and response steps. Use a comparison table to match common risks with practical controls and cleanup actions.
Graphing data
Make a science graph with correct axes, units and scale. Compare bar, line and scatter plots, work through sample data and avoid misleading trends.
Lab report format
Write each section of a lab report, connect evidence to claims, organize tables and graphs, and check units, citations and common grading issues.
Meniscus
Read a liquid meniscus at eye level, choose the correct curve, estimate between graduations, and use worked examples to report volume and uncertainty.
Scientific notation
How to convert a lab measurement into scientific notation, worked both directions, and the two rules that keep it written correctly.
Microscope parts
Identify the parts of a compound light microscope, learn each function, calculate total magnification, and follow a safe low-power focusing sequence.
Common lab equipment
Identify common lab equipment, compare its purpose and limits, choose a tool for each measurement, and follow practical setup and care checks.
Lab notebook
Keep a reliable lab notebook with dated plans, raw data, units, corrections and worked entries. Separate observations from calculations and conclusions.
Science experiment data table
Plan a science experiment data table before testing. Learn where variables and units go, how to record each trial, and how a clear table improves on a weak one.
