GOALS OF THE PROJECT
Increasing students’ consciousness and knowledge about climate change
Fortifying their autonomy and responsability
Enlarging their scientific skills
Reinforcing their cooperative skills
STRATEGY
Peer education: upper secondary school students will teach lower secondary school
pupils how to manage a chemistry lab experiment on climate change; after the lab
experience they will discuss together about it; finally the younger students will write a
scientific report assisted by their peer mentors.
School subjects involved in the project : chemistry, biology, geography, english
METHODOLOGY
step one :
upper secondary school students will write a PPT on laboratory safety and general
rules
lower secondary school students will study with their teacher the subjects involved
in the laboratory
step two :
upper secondary school students will prepare the layout of the report that will be
filled in by younger students once the lab experience is completed
l
lower secondary school students will read newspapers articles and books on
climate change
step three:
U
upper seconday school students will prepare cards on the elements and
compounds involved in the lab experience, they will also train for leading a
discussion on climate change
lo
lower secondary school students will formulate questions to ask their older
peers
products will be exchanged through the blog :
After the first three steps students will meet in the chemistry laboratory
step four :
upper seconday school students will explain the rules of conduct and safety that must be
observed in a chemistry lab, will manage the laboratory, will act as mentor to their younger
peers, will answer questions and evaluate the activity
lower secondary school students will perform the lab experiments and fill in the scientific report
step five :
upper secondary school students will create a leaflet ( both in Italian and in English) to promote
the experience
lower secondary school students will create a power point ( both in Italian and in English) on the
experience
A movie will be shot inside the chemistry laboratory to promote the
experience
A discussion will follow the chemical experience
The chemistry laboratory
Acid rain is rain with a pH lower than that of natural rainfall.
the main substances responsible for acid rain are sulfur and nitrogen oxides. Their presence in the atmosphere is partly
natural. However, human activities have increased their amount in the atmosphere.
We demonstrate in the chemistry laboratory that sulfur oxides are responsible for acid rain
PROCEDURE:
1 Pour 15 ml of water in 2 flasks;
2 add drops of methyl orange in 2 flasks and shake;
3 insert sulfur burned in a flask with the wand and wait for it to finish burning;
4 when the sulfur is exhausted, stopper the flask and shake;
Compare the 2 flasks.
