The Science Teacher
Nanoscience development affects almost every discipline of science, engineering, and technology. Not surprisingly, “the science of small” is also finding its way into science classrooms. In general, nano refers to a billionth of a meter—about 1/50,000 the width of a hair follicle. The term nanoparticle usually refers to small materials with a size of between 1 and 100 nanometers (nm). Because nanoparticles are so small, they have
a greater surface-area-to-volume ratio, causing them to be more reactive than larger particles and useful for various applications. Nanoscience is just one of many activities and investigations covered in this issue, which also looks at wildlife cover boards, using socio-scientific issues to teach argumentation, and finding patterns in chemical compounds.
