       Hi, my name is Christina Baum. I'm a fourteen-year-old German students. I'm writing to tell you

about an experiment we are doing at school with our Science teacher. At the beginning of this school

year, Frau Keller showed us films and we read articles about problems in the environment. One day she

said: "I want to know what you think. Please don't tell me what we should do or must do. Tell me what

each of you will do to protect the environment."

       She asked us to choose a topic, make a weekly plan and tell the class about it. Then we had to do

things to be "green" and write a report about our achievements. Some students said that they thought it

was impossible for a single person to contribute to the protection of the environment. Someone else said

that scientists should work harder to find new ways to produce energy.

       Frau Keller said that it is everyone's job to care for the health of the planet. After the first week everybody in class was excited about the project and wanted to continue to improve their results. Someone

suggested telling the other classes in the school. Now all 768 students at Hermann Stein School are

working on the project. At the end of the year, our class will write a report about what we have achieved.

       Next week I'll think about how not to waste water or make it dirty. I'm planning to try and use less

water every day, and also not use so much of the things that make it dirty. Every time I turn on the tap I

must think about how much water and soap I use.

       To use less water, this is what I'll do:

       —take a shower instead of baths;

       —turn off the tap while brushing my teeth;

       —use less washing-up liquid when washing dishes.
