Size Wheel

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA). Learners will be able to understand the difference in sizes and also learn about how small objects look when examined with special imaging technology such as a Scanning Electron Microscope. The activity includes images of: ant, dust mite, hair, virus, chromosome, spider web, penny, red blood cell, DNA, optic fiber, pollen grain, microchip, flagellum, plant cell, and silk threads.
