Our school clinic staff, the nurse Merve, gave us crucial information about cleaning. She told us that we have to be clean in order to be healthy. She mentioned what to do to protect ourselves from diseases and showed us how to wash our hands properly. We all washed our hands together in the class. All of us examined the posters and brochures which our nurse had brought to our class and recalled the tips. We don't want the microbes that make us sick in our bodies!
