A second set of experiment to demonstrate gas exchange and equilibration at the boundary layer between air and water. Pupils observe a high atmospheric CO₂ concentration will produce water acidification.

The following experiments demonstrate the role of plants in mitigating the acidification caused when CO₂ is dissolved in water.

The following experiments demonstrate that high level of atmospheric CO₂ produce ocean acidification. Effects on marine life are also shown.

An experiment designed to illustrate the impact of carbon dioxide on microalgal growth in the aquatic environment.

These experiments explore the effects of water temperature on the solubility of CO2 in water.

In this experiment, pupils compare the effect of increasing atmospheric CO₂ concentrations on seawater and freshwater bodies like lakes and streams.

Pupils learn how to produce CO₂ and they perform simple experiments to find out some of its properties.

Using a carbon dioxide sensor, pupils measure carbon dioxide concentrations in the classroom and explore what factors can influence this.

Examples of demonstration experiments which can be performed in the class room using a carbon dioxide analyser.

A selection experiments to motivate teachers and scientists to find their own experiments or to improve some of the presented ones. Most were collected from the experiment archive of the physics division of the Neufeld Gymnasium in Bern.

An activity with colored balls and climate scenarios, designed to give an impression of the reliability of the statistics of predictions.
