The week of sustainability begins with commitments on a sheet.

“I am a vegitarian”, scrawled a pupil on it with a felt pen.

It also says: “I have a passive house.” The banner bears the heading “Where am I sustainable?” And hangs in the courtyard of the Integrated Comprehensive School in Nordend.

Another answer is: "I almost never shower!"

This could be a joke or an excuse for sparse grooming.

Perhaps the writer has also misinterpreted the workshop “Clean without cleaning”, which deals with the lotus effect: This ability of plants to clean themselves can be used to keep surfaces clean.

Not so much when showering, but for example with impregnation sprays and special facade paint.

The young people in the room first experiment with two types of leaves.

Niklas put a drop of water on the smooth surface of the nasturtium.

Flour and healing earth serve as dirt.

The drop pearls.

Niklas stares through the microscope's eyepieces.

Does the water behave differently with the lettuce?

"I am not that far yet."

Goal: An environmentally friendly school

Since Tuesday, the IGS has been devoting itself to sustainability for four days with the support of parents and external parties. The subject is also important to the school, says headmistress Susanne Frye. There is the subject “project” in grades nine and ten. The young people can choose between different offers. Luzie and Lilli have chosen EnergIGS. “We are working on becoming an environmentally friendly school,” says Luzie. Paper should be used on both sides, returnable bottles are not allowed in the residual waste, and the rule applies: walk instead of elevator. The school is also collecting funds for a reforestation project in Costa Rica, also with a sponsored run. Teacher Matthias Walter, who also organizes the project week, reports on this. He hopethat in the end everyone can do something with the United Nations Sustainable Development Goals. Another banner on the school building reads: "4 Days - 17 Goals."

In a classroom, a young Indian speaker speaks about schools and Corona in her home country.

As Walter reports, she is doing an internship in Frankfurt and came to the school through contact with parents.

In other groups she reports on climate change in India.

Ida, Frida and Giulietta let it pour and dribble.

To do this, they use two green plastic watering cans.

One says “heavy rain” and the other says “light rain”.

A slope of earth is piled up in a box, which becomes steeper or flatter with wedges under the box.

“We're trying to see how much the rain washes the ground away.” Next to the experimental setup is a piece of coarse woven fabric with a few Playmobil fir trees on it: the vegetation cover.

The girls have already figured out what it's good for.

"This means that the soil is less eroded."
