During the first week students of our school tried to find the causes of climate changes in our city and country. They have been working in groups to prepare the list of cliamte changes causes. The youngest students prepared some graphical posters because of language difficulties. They played some interactive educational games connected with the topic. Students are familiarized with vocabulary connected with the climate topic, like greenhouse gases, acid rain, reneweble energy. Moreover, they can define what the climate change is, and they see teh difference between climate and weather.
During the second week, we made a long list of the effects of climate change in our city and country. Moreover, students checked how increasing the concentration of carbon dioxide and other greenhouse gases in the atmosphere affects the acidification of water. They compared the pH of water with dissolved greenhouse gases and distilled water using acid-base indicators. They have used methyl orange, universal indicator paper, litmus and decoction of red cabbage.
This week some students gathered all causes and effects of global climate change and presented their work in front of class.
The fourth week was a great challenge for us - we were looking for solutions to prevent climate change. The youngest students presented their own ideas in the form of art works.
Our students have also conducted some experiments. First of all, they found a link between the problem of plastics and climate change:
- increasing CO2 emissions during the production of plastic,
- plastic microparticles in the oceans are toxic to phytoplankton, which takes carbon dioxide from the atmosphere.
For these resons they have prepared bioplastic in two different ways, first made of potato starch and glycerin, and the second with the use of milk and vinegar.
Edible water bottles have also been prepared as an idea to reduce plastic consumption.
The last experiment gives the bottle a "second life" as it was used as a self-watering pot. This solution allows us to save the amount of water used.
All activities have been documented with photos.
