In this study, the attitudes of Israeli children aged 6 to 15 years were surveyed regarding their conceptions of plants as living things. It was desired to find out whether children consider plants to be alive, the knowledge differences between the different age groups in the study, how children classify plants according to biological criteria and correlations between the classification according to the concept of living/non-living and the classification according to biological criteria. Both individual interviews and paper-and-pencil questionnaires were used in which children were asked to classify animals, plants and inanimate objects. It was found that: (1) there was a high percentage of incorrect classifications of plants at all ages; and (2) there were no consistent connections between the classification of plants into living/non-living and according to biological criteria. The study proposes that part of the deviance of Israeli children from others in other research studies could be explained by characteristics of the Hebrew language. (CW)
