Revision and Prior Knowledge of Energy
Law of Conservation of Energy
Practical demonstrations
Conversions /transformations
Criterion A
Criterion B
Criterion C
How is an appropriate amount of information communicated through an energy transformation diagram?
Energy chains
Protocol (flow diagrams) for recording energy changes
Simple experiments:
eg, falling bodies, trampolines, rubber bands, bouncing balls, pendulums
Criterion A
Criterion B
Criterion C
How is there always the same amount of energy after an energy transformation?
Heat: transformations to and from heat
(NOT transfer)
Energy Experiments: consolidate understanding of energy changes
eg, match striking, radiometer, light meter, magnetic coils, electromagnets
energy changes - chemical, mechanical, sound
Criterion A
Criterion B
Criterion C
How is energy quantified? What is a joule?
Kinetic and Potential Energy Formulae
efficiency of energy transformations
Criterion A
What are the components of velocity? How is this quantified?
Conduct simple experiments:
to learn how to calculate average velocity of a moving object from distance and time
Criterion B
Criterion C
What is efficiency? What is the efficiency of an energy transformation? How is energy efficiency calculated?
Formative tasks - simple experiments
continue investigating energy changes (KE, PE - rubber band sling shot, motion of a car trolley, etc)
summative assignment practice - hypothesis statement, method, etc
Criterion B
Criterion C
What should the variables be when designing an investigation into the efficiency of an energy transformation?
How do I quantify my independent and dependent variables?
Plan & organise for assignment
aim, hypothesis, variables
Start the “Energy Transformations” assignment
collaboratively collect data in-class
individually continue to write up the practical report (at home)
Criterion B
Criterion C
What do I know and understand about energy transformations?
How can a household use energy more efficiently?
Revision for test
Unit Test
Criterion A

Energy Efficiency
Energy Conservation
use Lab Energy kit, or
Energy audit/CSIR0 project.
