Science

In the Climate change and biodiversity unit, they will build on this knowledge to learn about the impact of agriculture and deforestation on biodiversity, and to more thoroughly consider the effects of climate change on biodiversity and food production.

In the unit Climate change and living sustainably, pupils were introduced to the greenhouse effect, global warming and the impact of climate change on weather events. It explored some actions that can be taken to use resources, and to live, in a sustainable way.

In this unit pupils learn about greenhouse gas emissions from transport and industry, and the use of renewable energy resources and changes to transport infrastructure that could reduce emissions.

Which of these can be used to work out temperatures in the years before measurements were taken?

What can be used to measure the amount of carbon dioxide in the atmosphere thousands of years ago?

it would definitely slow down how quickly the carbon dioxide level goes up

it would definitely stop the carbon dioxide level going up

it would definitely reduce the carbon dioxide level

What would reducing carbon dioxide emissions do to the level of carbon dioxide in the atmosphere?

A model of a bath filling with water can represent the amount of greenhouse gases in the atmosphere. Match each part of the model with what it represents.
