carry out procedures, controlling the major variables and adapting or extending procedures (e.g., perform an experiment to demonstrate the equivalency of work done on an object and the resulting kinetic energy; design a device that converts mechanical energy into thermal energy)

compile and organize data, using appropriate formats and data treatments to facilitate interpretation of the data (e.g., use a computer-based laboratory to compile and organize data from an experiment to demonstrate the equivalency of work done on an object and the resulting kinetic energy)

use library and electronic research tools to collect information on a given topic (e.g., compile information on the energy content of fuels used in Alberta power plants; trace the flow of energy from the Sun to the lighting system in the school, identifying what changes are taking place at each stage of the process)

select and integrate information from various print and electronic sources or from several parts of the same source (e.g., create electronic documents, containing multiple links, on using alternative energy sources, such as wind or solar, to generate electricity in Alberta; relate the importance of the development of effective and efficient engines to the time of the Industrial Revolution and to present-day first-world economics)

compile and display evidence and information, by hand or using technology, in a variety of formats, including diagrams, flow charts, tables, graphs and scatterplots (e.g., plot distance - time, velocity - time and force - distance graphs; manipulate and present data through the selection of appropriate tools, such as scientific instrumentation, calculators, databases or spreadsheets)

identify limitations of data or measurement (e.g., recognize that the measure of the local value of gravity varies globally; use significant digits appropriately)

interpret patterns and trends in data, and infer or calculate linear and nonlinear relationships among variables (e.g., interpret a graph of changing kinetic and potential energy from a pendulum during one-half of a period of oscillation; calculate the slope of the line in a distance - time graph; analyze a simple velocity - time graph to describe acceleration; calculate the area under the line in a force - distance graph)

compare theoretical and empirical values and account for discrepancies (e.g., determine the efficiency of thermal energy conversion systems)

state a conclusion based on experimental data, and explain how evidence gathered supports or refutes the initial hypothesis (e.g., explain the discrepancy between the theoretical and actual efficiency of a thermal energy conversion system)

construct and test a prototype of a device or system, and troubleshoot problems as they arise (e.g., design and build an energy conversion device)

propose alternative solutions to a given practical problem, identify the potential strengths and weaknesses of each and select one as the basis for a plan (e.g., assess whether coal or natural gas should be used to fuel thermal power plants in Alberta)

evaluate a personally designed and constructed device on the basis of self-developed criteria (e.g., evaluate an energy conversion device based on a modern or traditional design)

represent large and small numbers using appropriate scientific notation

select and use appropriate numeric, symbolic, graphical and linguistic modes of representation to communicate ideas, plans and results (e.g., use appropriate Système international (SI) units, fundamental and derived units; use advanced menu features within a word processor to accomplish a task and to insert tables, graphs, text and graphics)

work cooperatively with team members to develop and carry out a plan and to troubleshoot problems as they arise (e.g., develop a plan to build an energy conversion device, seek feedback, test and review the plan, make revisions, and implement the plan)
