Bacteria exists all around us – in the air, in the water, in the soil and in the bodies of other living things. Although when students typically think about bacteria they think of disease, most bacteria are actually helpful. This lesson aims to help students develop an awareness of the vast number of bacteria that exist all around us, understand that bacteria play a vital part in the lives of people and that while some bacteria are harmful, most are useful, and provide students with a visual experience which will help develop their skills in distinguishing minute differences in microscopic life. Kit contains ten identical sets of eight photomicrographs, ten instruction texts, ten student worksheets and a reproducible teacher’s guide. Elementary and middle school grades
