And here in this picture, there are two kinds of colonies, they are bacterial colony and fungal colony. But if we want to cultivate purebred colony what should we do? Can you imagine? [Students]…… [Teacher] Ok, doctor Koch, in 1872, had found the best way to cultivate the purebred colony. And the process is at first he made medium, the medium is made of agar and nutrients which are needed by bacteria and fungi. Then he inoculated the bacteria and fungi which he wanted on the medium. At last there become many colonies but they are all purebred. Now let’s review the cultivation process of bacteria and fungi. [Teacher]Here if we want to cultivate the purebred colony we should make medium and next is…… [Students]Inoculate!! [Teacher]Good, how about the last part? [Students]Cultivate! [Teacher]Greet, but we know there are many bacteria and fungi living around us so before the process of inoculation we should…… [Students]Sterilize!! [Teacher]Very good we have finished it now your home work please design an experiment about how to cultivate bacteria and fungi which is on our hand Ok? [Students]Ok!! [Teacher]Ok class is over!! Bye-bye! [Students]Good-bye sir.Activity 3NotesWriter by: _Zhang xinyuan_E/11/2007学生材料/教案（院系、姓名）6/6
