Change
Energy drives change. Conduction, convection, radiation, energy transformations, chemical reactions, geological processes and the rock cycle.
Lessons
12 totalEnergy transfer — conduction, convection, radiation
Three ways heat moves from hot to cold.
Potential and kinetic energy
Stored energy and the energy of motion.
Energy transformations
Energy changes form but is never created or destroyed.
Open and closed systems
How energy enters, leaves or stays within a system.
Physical and chemical changes
Some changes are reversible — some make something brand new.
Chemical reactions and word equations
Reactants go in, products come out — describe it in words.
Energy in chemical reactions
Some reactions release heat, others absorb it.
Respiration and photosynthesis as chemistry
Life's energy reactions — written as chemical processes.
Tectonic plates and plate tectonics
The slow, powerful movement beneath our feet.
Earthquakes and volcanoes
Geological evidence — including from First Nations accounts — of a changing Earth.
Rocks, minerals and the rock cycle
How geological processes transform rocks over millions of years.
Fossils and geological time
Evidence in rock that tells the story of life on Earth.
