Key ideas
Weather instruments measure specific variables: thermometer (temperature), barometer (air pressure), hygrometer (humidity), anemometer (wind speed), rain gauge (precipitation).
Seasons are caused by Earth's axial tilt (23.5 degrees), which changes the angle and duration of sunlight through the year - not distance from the Sun.
Accurate readings require correct placement, calibration, and consistent units.
A location's latitude sets how directly it is heated across the seasons.
Local observations gain meaning when integrated with regional and national network data (weather stations, buoys, satellites).
Watch out for
- Thinking one instrument or one reading is enough to describe weather - many variables and repeated readings are needed.
- Thinking seasons happen because Earth is closer to the Sun in summer - they are caused by axial tilt, not distance.
- Thinking local data alone predicts weather - weather moves in from elsewhere, so network data matters.

Key ideas
WHMIS (Workplace Hazardous Materials Information System) uses standardized hazard symbols and safety data sheets to communicate risks.
Ionic compounds form between a metal and a non-metal; the formula balances the ion charges (e.g. NaCl, CaCl2).
Safe technique includes goggles, avoiding contamination, never returning chemicals to stock bottles, and correct disposal.
Molecular (covalent) compounds form between non-metals and use prefixes (mono-, di-, tri-) to show numbers of atoms (e.g. CO2 = carbon dioxide).
Reading a label/SDS before use tells you the hazards and first-aid steps.
Watch out for
- Thinking only 'strong' chemicals need safety precautions - all lab chemicals require proper handling.
- Thinking you can name ionic and molecular compounds the same way - ionic uses charge balance, molecular uses prefixes.
- Thinking all waste can go down the drain - many chemicals need special disposal.

Key ideas
Motion experiments measure distance/position (metre sticks, measuring tapes) and time (stopwatches, motion sensors, tickertape).
Motion technologies (vehicles, elevators, sensors, speed cameras) are designed to produce, measure, or control motion.
Accuracy requires correct units (metres, seconds), consistent zero points, and reading instruments at eye level.
Describing a design means explaining how its parts work together to achieve its function.
Correct terminology (distance, time, speed) makes data unambiguous.
Watch out for
- Thinking a single measurement is enough - repeating reduces random error.
- Thinking evaluating a technology means only listing its good points - it weighs strengths against limits.
- Thinking units are optional - a number without a unit is meaningless in physics.

Key ideas
A paradigm is a shared way of thinking; a paradigm shift is a fundamental change in that thinking.
Short-term stress (a storm, a spill, a heatwave) causes an immediate response the ecosystem may recover from.
Society's view of nature has shifted from 'limitless resource to exploit' toward 'finite system to sustain'.
Long-term change (climate change, sustained pollution, succession) reshapes an ecosystem over time.
Such shifts change laws, industries, and everyday choices (recycling, protected areas, emissions limits).
Watch out for
- Thinking views of the environment have always been the same - they have shifted significantly over time.
- Thinking short-term stress and long-term change are the same - they differ in duration and reversibility.
- Thinking a paradigm shift is just a new opinion - it is a broad change in shared understanding and behaviour.
