Greenhouse effect experiment

Investigating how carbon dioxide affects temperature

In this activity learners will discover the effects of mixing chemicals and the warming effects of the sun. They will undertake a controlled experiment to investigate how gases in the atmosphere affect the heat in an enclosed environment.

This activity could be used as a main lesson activity, to introduce the concept of the earth’s atmosphere, or as part of a series of lessons investigating environmental issues, the effect of global warming and greenhouse gasses.

This is one of a set of resources designed to allow learners to use practical methods to support the delivery of key topics within Design & Technology, Science, Maths and Humanities. This resource, developed with the support of National Grid ESO, in a practical experiment that investigates how the greenhouse gas carbon dioxide affects the temperature is a closed environment. National Grid ESO ensure that Great Britain has the essential energy it needs by ensuring supply meets demand every second of every day.

This activity can be simplified (particularly for less able students) by providing learners with pre-prepared jars and cling film.

This activity is designed to take between 50-60 minutes to complete.

Tools/resources required
4 large empty jars
Cling film
Scissors
Masking tape
Permanent marker
Bicarbonate of soda
White vinegar
Measuring cups and spoons
Elastic bands
Thermometers (non-contact infra-red type preferred; if using a traditional contact type one thermometer will be needed for each jar)
Heat source (radiator with a flat top or a sunny window)

The engineering context
Many human activities result in emissions of greenhouse gases. These can have a significant effect changing the climate and weather conditions that we experience. There is a wide range of possible ways to reduce these emissions. Engineers play a huge role in such areas, developing and implementing processes and materials that produce lower levels of greenhouse gas emissions, such as sustainable methods of power generation. Engineers also have a significant social influence on our behaviours as a society when we consider the future implications of our actions and consumption.

Suggested learning outcomes
By the end of this free resource students will be able to understand that carbon dioxide is a greenhouse gas and be able to make a reaction between 2 materials/chemicals.

All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students’ and your schools’ needs.

The activity sheet includes teacher notes, guidance, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved UK nations; England, Northern Ireland, Scotland and Wales.
