 In the 17th century, Robert Hooke marvelled at a flea through his flea-glass. This week, Year 6 students were fascinated by what they could see and draw using microscopes in the high school laboratory. Of course, these instruments were considerably more sophisticated than the magnifying glass used by Hooke. They had multiple lenses, in-built light sources and precise controls to adjust movement and focus. When the specimen was finally brought into sharp view, how beautiful, grotesque or puzzling it often seemed! Look here: the tip of a corn root; a blood smear; the mouth parts of a butterfly; the cells of a fern. -mjp |   |
