Spreadsheets, Formulas & Charts for NEB Practical Work Practice Set: NEB 11 Computer

Worked practice

Build the result from meaning, not memory

A spreadsheet stores typed data in cells, calculates with formulas and summarizes patterns through tables and charts. Correct references and clean data are more important than decoration.

The governing relationship is Formula workflow: identify inputs→choose relative/absolute references→calculate→copy carefully→validate totals→select a chart matching the question. Check the convention, geometry or boundary condition before calculation.

Independent practice ladder

1. Define the key physical quantities and give their SI units.
2. Draw and label the relevant wave, ray, mode or energy diagram.
3. Recalculate the worked example after changing one input by a factor of two.
4. Explain the result without equations.
5. Create a Nepal-relevant situation such as a classroom speaker, musical pipe, optical slit or thermal machine.
6. Compare two cases and predict the larger output before calculating.
7. Find and repair one deliberately wrong sign, node or unit.
8. Write a three-mark answer and a five-mark answer.

Answer protocol: diagram → known data → principle → symbolic equation → SI substitution → result → physical check. Typing calculated results instead of formulas, omitting =, using the wrong reference type, or choosing a pie chart for unsuitable comparisons.

NEB answer method

Model → evidence → equation → check

First identify the system and what the question asks. Label the diagram, apparatus or reaction with SI quantities, then state the principle before selecting an equation. Solve symbolically where possible and check units, limiting cases and chemical or physical meaning.

Make the idea concrete in Nepal

Connect the model to a school laboratory, household technology, health, environment, energy or local material. The example should clarify the science rather than merely mention a place. Compare a prediction with an observation and record uncertainty.
