the average of all the temperatures across the world over a year

the biggest possible difference between a measured value and the true value of the quantity being measured

the certainty with which a measurement or conclusion will remain the same when it is checked

Human activity and climate change

Combined science

In the Industrial chemistry unit, pupils will learn about chemical, industrial, environmental and economic factors of some large-scale chemical processes.

In the Carbon Cycle and Climate Change unit, pupils learned about the carbon cycle, the formation of sedimentary rocks, and the impact of burning fossil fuels.

This unit explores the composition and evolution of Earth’s atmosphere, evidence of climate change, and effects of pollutants like sulphur dioxide. It highlights scientific explanations, ethical considerations, risk evaluation, and the role of peer review in communication.

Which of these actions does not reduce our individual carbon footrprint?

Different groups get the same results using different methods.

Different groups get the same results using the same method.

Averages of repeat measurements are used, ignoring anomalous results.

Averages of repeat measurements are used.
