Energy accounting in physical systems is the focus of this Grade 11 Science worksheet, helping students track energy entering, leaving, and remaining within a defined system. Students apply conservation of energy to heat, work, gravitational energy, elastic energy, thermal energy, and chemical energy while connecting computational models with measured data.

Build Energy Accounting Skills

The reading passage introduces system boundaries and explains how energy can cross a boundary as heat or work while remaining stored in different forms. Students examine examples involving a roller-coaster car and a battery, then use the ideas of energy transfer and transformation to reason about physical systems.

Practice focuses on interpreting energy models, identifying changes in stored energy, and applying conservation of energy quantitatively. Students work with situations involving gravitational potential energy, electrical energy transferred from a battery, elastic energy in a compressed spring, and differences between computational predictions and experimental measurements.

Reason From Models and Data

The worksheet includes multiple-choice questions, true/false statements, short-answer questions, a labeled diagram, a categorization task, and a short note. Questions ask students to identify the purpose of an energy accounting model, interpret system boundaries, calculate remaining stored energy, recognize heat crossing a boundary, and explain why measurements may differ from model predictions.

Students also consider how measurement uncertainty, incomplete system boundaries, and energy transfers omitted from a model can affect agreement between predictions and observations. This reinforces the scientific practice of comparing quantitative computational models with measured data and revising models when needed.
