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

Human activity and climate change

Chemistry

Earth's atmosphere (approximate values)

Evolution of Earth's atmosphere

Burning hydrocarbons

Atmospheric pollutants

Acid rain and chemical weathering

Greenhouse gases

Global climate change and the effects

Ozone layer: a story of global success

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.

Atmosphere and changing climate

the release of carbon dioxide into the atmosphere

biggest possible difference between a measurement and the true value

the certainty with which a measurement will be the same when checked

Match the key term with the correct definition.

What relationship does the graph show between the amount of atmospheric carbon dioxide and the year?

the temperature is measured with two different thermometers

the thermometers used are each accurate to plus or minus one degree C

Which options are reasons why there is some uncertainty in a measurement of the average temperature of a science lab?

Wearing a thick jumper outside on a cold day.

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.

Each measurement is repeated to check it is correct.

Put these strategies in order, starting with the one that gives the strongest evidence that a set of results are reliable?

digital thermometer with a range of 0 to 100 degrees C

an alcohol thermometer with a range of -30 to +50 degrees C

a clinical thermometer measuring to the nearest 0.1 degrees C

Which measuring instrument can be used to measure the outdoor temperature in the UK most accurately, throughout the year?

What word or phrase is used to describe a pattern between variables which shows both variables changing at the same time?

turn off electrical appliances when not in use

Which of the following are ways humans can reduce the amount of carbon dioxide emitted because of their actions?

Which of these gases cause the most global warming?
