  4. Just How Small are They? 1 km = 1000 m 1 m = 100 cm 1 cm = 10 mm 1mm = 1000 μm (micrometre) Q1) How many μm in 2 mm? Q2) How many μm in 1 cm?

  5. Assume 1000 micrometres = 1 metre Make 2D scale drawings of each of the objects so you can get an idea of just how small they are.

  6. Assume 1000 micrometres = 1 metre Make 2D scale drawings of each of the objects so you can get an idea of just how small they are.

  7. What have you realised about microbes and their size? How does their small size make them successful?
